What Is LinkedIn InMail? How to Write InMails That Get Responses

LinkedIn has more than one billion members across more than 200 countries, yet reaching the right person at the right time remains one of the most persistent challenges in sales, recruiting, and professional outreach. Most of those people are not in your network, and a cold connection request rarely tells enough of a story to earn a reply. That is exactly the gap InMail was designed to fill.

InMail lets you send a private message directly to any LinkedIn member, whether you are connected or not, as long as your account tier supports it. But having the ability to land in someone’s inbox is only the beginning. With response rates under pressure and inboxes growing more crowded, knowing how to write a message that actually earns a reply matters far more than simply having credits to spend.

This guide covers everything you need to know — how InMail works, how the credit system operates, what the data says about response rates, and how to write messages that people genuinely want to answer.

What Is LinkedIn InMail?

LinkedIn InMail is a private messaging feature that allows LinkedIn Premium account holders to send messages to any LinkedIn member, including people outside their first-degree network. Unlike a standard LinkedIn message, which can only be sent to first-degree connections, InMail bypasses the connection requirement entirely.

The word “InMail” is specific to LinkedIn’s product. It is not simply a premium version of the standard message box — it is a distinct communication channel with its own credit system, character limits, analytics, and delivery behaviour. When an InMail arrives in a recipient’s inbox, it is displayed differently from a regular message, and the recipient has the option to reply, decline, or ignore it. This distinction matters because how people respond to an InMail — or choose not to — directly affects whether you get your credit back.

How InMail differs from a regular LinkedIn message

A regular LinkedIn message can be sent to anyone in your first-degree network at no credit cost and with no character restriction. InMail, by contrast, requires a Premium subscription, consumes credits from a monthly allowance, and is governed by both subject line and body character limits. The functional difference is reach: standard messages stay within your existing network, while InMail extends your reach to anyone on the platform.

How InMail differs from a connection request

A connection request comes with an optional note of up to 300 characters and is a request for ongoing access — you are asking someone to let you into their network. An InMail is a standalone message with a subject line and a full message body, and it delivers immediately without waiting for the recipient to accept anything. That immediacy comes at a cost — literally — which is why choosing between a connection request and an InMail is a strategic decision, not an arbitrary one.

Who can send and receive InMails

Any LinkedIn member with a Premium subscription (Career, Business, Sales Navigator, or Recruiter) can send InMails. The number of credits available per month depends on the specific plan. On the receiving end, any LinkedIn member can receive an InMail, with one exception: members who have turned off InMail in their privacy settings will not be reachable this way. Members with Open Profile status, however, can be messaged for free by anyone — no credits required — which is covered in the next section.

3 Types of LinkedIn InMail

Not all InMails work the same way. There are three distinct types, each with a different cost structure, use case, and delivery mechanism. Conflating them is one of the most common sources of confusion for new LinkedIn Premium users.

Free InMail (Open Profiles)

Free InMail is not a product tier — it is a situation. When a LinkedIn member enables “Open Profile” on their account, they are signalling that they are willing to receive messages from anyone on the platform, regardless of connection status. Crucially, sending a message to an Open Profile member costs the sender zero credits.

This is significant for outreach volume. If you are prospecting a large list, identifying Open Profile members first and messaging them without spending credits allows you to reserve your InMail allowance for members who cannot be reached for free.

What is Open Profile status and how to identify it

Open Profile is a setting available to LinkedIn Premium members. When enabled, a gold Open Profile badge appears on the member’s profile. If you visit a profile and see the option to “Message” rather than “Connect” or “InMail,” and if no credit deduction is shown, that person is likely an Open Profile member. Sales Navigator also allows you to filter searches specifically for Open Profile members, making it possible to build entire prospect lists of people you can contact for free.

Paid InMail (Premium accounts)

Paid InMail is the standard credit-based InMail tied to a LinkedIn Premium subscription. Every Premium plan comes with a set number of InMail credits per month. When you send an InMail to a non-connection who does not have Open Profile enabled, one credit is deducted. If the recipient replies, that credit is refunded — this is LinkedIn’s built-in incentive to encourage quality outreach rather than volume spamming.

Paid InMail is the type most sales professionals, recruiters, and job seekers will use day-to-day. It is personal, appears in the recipient’s LinkedIn inbox, and can be sent from either a standard Premium account or specialised tools like Sales Navigator or Recruiter.

Sponsored InMail (Message Ads)

Sponsored InMail — now officially called LinkedIn Message Ads — is an entirely different product. It is not a feature of your personal Premium account; it is a paid advertising format purchased through LinkedIn’s Campaign Manager. Sponsored InMail messages are sent on behalf of a company page or brand, delivered to targeted audience segments, and cannot receive a personal reply the same way organic InMail can.

How Sponsored InMail differs from personal outreach

The difference is fundamental: personal InMail comes from a real individual profile, lands in the inbox alongside other messages, and invites genuine one-to-one conversation. Sponsored InMail is a marketing broadcast — it reaches thousands of people simultaneously, is clearly labelled as “Sponsored,” and is optimised for click-through to a landing page rather than a dialogue. Both have their place, but they serve entirely different goals. If your aim is a personalised conversation with a specific person, Sponsored InMail is not the tool you need.

InMail Credits: How They Work

The InMail credit system is one of the most misunderstood aspects of LinkedIn Premium. People often run out of credits early in the month and do not fully understand why, or they do not realise that credits can be earned back. Here is a complete, consolidated guide to how the system operates.

How many credits you get per subscription tier

LinkedIn allocates InMail credits monthly based on your subscription plan. As of current published information:

• LinkedIn Premium Career: 5 InMail credits per month
• LinkedIn Premium Business: 15 InMail credits per month
• Sales Navigator Core: 50 InMail credits per month
• Sales Navigator Advanced: 50 InMail credits per month
• Recruiter Lite: 30 InMail credits per month
• LinkedIn Recruiter (full): 150 InMail credits per month

These allocations reflect the intended use case of each plan. Career is designed for individual job seekers making selective outreach; Sales Navigator and full Recruiter are built for high-volume professional outreach.

When credits are refunded (replied vs. declined vs. ignored)

This is where most users leave credits on the table. LinkedIn’s refund policy is straightforward:

• If the recipient replies to your InMail within 90 days of you sending it, the credit is refunded to your account. This applies even if the reply is negative.
• If the recipient does not reply within 90 days, the credit is not refunded.
• If the recipient declines the InMail (by clicking the decline option), the credit is also refunded. LinkedIn treats a decline as engagement — the recipient saw and acted on your message.

This policy creates a clear incentive: send InMails that prompt some kind of response, even if it is not the one you hoped for. A rejection that gets you a credit back is more valuable than being ignored.

When credits renew

InMail credits renew on a monthly basis, aligned with your subscription billing date. Unused credits do not carry over indefinitely — LinkedIn allows a maximum rollover, meaning unused credits accumulate only up to a cap (typically around 150 credits for most plans) before they are forfeited. Regularly auditing your credit balance ensures you are not wasting your allowance through inaction.

How to buy additional InMail credits

If you exhaust your monthly allocation before your renewal date, LinkedIn allows you to purchase additional InMail credits. Pricing varies and is subject to change, but the option is typically available through your Premium account settings under “InMail credits.” For most users, a better approach is to audit outreach quality before buying more — if existing InMails are not generating replies, more volume is unlikely to fix the problem.

How to check your remaining credits

To check your InMail credit balance: navigate to your LinkedIn Premium subscription page (accessible via the “Me” dropdown at the top of your LinkedIn feed), then select “Manage Premium account.” Your remaining InMail credits and renewal date are displayed on that page. In Sales Navigator, credit balance information is available under “Settings” and then “InMail credits.”

InMail Character Limits by Subscription

LinkedIn enforces character limits on both the subject line and the body of every InMail. These limits exist across all plan types, though they vary slightly between products.

Subject line character limit

The subject line character limit is consistent across all LinkedIn InMail types: 200 characters. In practice, effective subject lines are considerably shorter — typically between 40 and 80 characters — because longer subject lines are truncated in inbox previews on mobile devices, where a substantial portion of LinkedIn’s users check messages.

Body character limit — Premium, Sales Navigator, Recruiter

• LinkedIn Premium (all tiers): Up to 1,900 characters in the message body
• Sales Navigator: Up to 1,900 characters in the message body
• LinkedIn Recruiter: Up to 1,900 characters in the message body

The body limit is consistent across paid InMail types. While 1,900 characters gives you substantial room, research into outreach messaging consistently shows that shorter messages outperform longer ones. Having the character allowance does not mean you should use it.

Why the limit matters for response rates

Character limits are not just a technical constraint — they are a design signal. LinkedIn built InMail to encourage concise, purposeful communication. Data from LinkedIn’s own research indicates that InMails under 400 characters perform better than longer messages. When you write an InMail that runs close to the 1,900-character ceiling, you are likely overwhelming the reader, burying your call to action, and reducing your chance of a reply. The limit sets a ceiling; your aim should be to stay well below it.

Is InMail Worth It? Benefits and Limitations, Honestly Assessed

InMail is a genuinely useful tool in the right circumstances. It is also genuinely expensive and genuinely limited if used incorrectly. The honest answer to “is InMail worth it?” depends entirely on your use case, your alternative options, and how well you write your messages.

The genuine advantages: direct access, no connection required, professional signal

The core value proposition of InMail is direct, unrestricted access. You can reach a VP at a Fortune 500 company, a top-performing candidate who is not actively job hunting, or a potential partner at a firm you have no existing relationship with. None of that is possible through standard LinkedIn messaging without a prior connection.

InMail also carries a professional signal. Because it requires a Premium subscription and consumes credits, recipients generally understand that the sender has made a deliberate, paid choice to reach out to them specifically. This is different from a cold email, which carries no friction or cost signal, and it is different from a connection request, which feels more casual and less substantive.

The real limitations: cost per send, declining response rates industry-wide, credit caps

The cost per InMail is meaningful. On a LinkedIn Premium Business plan, 15 credits costs the subscription fee — meaning each InMail represents a real per-unit investment. On plans with lower credit allocations, the implicit cost per message is even higher. This cost is difficult to justify if response rates are low.

Response rates for InMail have declined over time as the channel has grown more crowded. LinkedIn’s own data suggests an average InMail response rate around 10 to 25 percent, depending on industry, role, and message quality — significantly lower than it was when InMail was a newer and more novel channel. The credit cap also means you cannot run unlimited campaigns; you are forced to be selective.

When InMail is the right tool — and when it isn’t

InMail is the right tool when:

• The person you need to reach is not in your network and is unlikely to accept a connection request from a stranger
• The stakes of the conversation justify the credit cost (a senior hire, a major prospect, a strategic partnership)
• You have done enough research to write a message personalised enough to earn a response
• You have tried other channels and they have not worked

InMail is the wrong tool when:

• You want to reach a large number of people quickly at low cost — email is better for volume
• Your message is templated and generic — a bad InMail wastes a credit and damages your credibility
• The person has Open Profile enabled — in that case, message them for free

InMail vs. connection request: which to use when

Use a connection request when you have a genuine reason to want an ongoing relationship and when a 300-character note is enough to explain why. Use InMail when you need to make a substantive case, have a specific ask that benefits from a full message, or need to reach someone who is unlikely to accept a blind connection request. InMail is not necessarily better — it is just more room to make your case, at a cost.

InMail vs. cold email: how to decide

Cold email is cheaper at scale and allows more customisation in formatting and length. InMail is better when you cannot find a verified email address, when your prospect is more active on LinkedIn than in their inbox, or when the InMail’s professional context gives you a credibility advantage that a cold email would not. Many effective outreach sequences use both channels, in deliberate order.

What Makes an InMail Get a Response? The Data

Before writing a single word of your message, it helps to understand what LinkedIn’s research and independent outreach studies say about the variables that move response rates.

Average InMail response rate benchmarks

LinkedIn’s internal data, cited in their own marketing communications, reports that InMail has a response rate approximately 3 times higher than standard email. LinkedIn has also published that InMails sent to people with whom you share a group or connection see higher response rates than cold InMails to complete strangers. Independent sales benchmarking research from organisations like TOPO and Outreach has found that personalised InMail response rates typically fall between 10 and 25 percent, with top-performing senders achieving 30 percent or above through strong personalisation and precise targeting.

These benchmarks matter as a baseline — if your response rate is significantly below 10 percent, something structural is wrong with your messages, your targeting, or both.

Factors that most influence open and reply rate

Subject line impact

LinkedIn’s own research has found that InMails with no subject line actually outperform those with subject lines in some contexts — recipients see the first line of the message body instead, which can be more intriguing than a generic subject. However, in most cases, a relevant and specific subject line increases open rates. The key word is “specific” — subject lines that reference something particular about the recipient outperform generic ones significantly.

Message length sweet spot

LinkedIn has published data indicating that shorter InMails generate higher response rates. Their analysis found that InMails of 400 characters or fewer performed better than longer messages. A study by Drift found that sales emails under 200 words generate higher reply rates than longer ones — a finding that generalises well to InMail. The ideal InMail is long enough to make a coherent, personalised case and short enough to be read in under 30 seconds.

Day and time of send

LinkedIn’s data suggests that InMails sent on Tuesdays, Wednesdays, and Thursdays outperform those sent on Mondays and Fridays. Monday inboxes tend to be catch-up overload; Friday inboxes tend to be cleared perfunctorily before the weekend. Mid-week messages land when recipients are more likely to be engaged and responsive. Time of day data suggests that mid-morning (between 9 and 11 a.m. in the recipient’s time zone) tends to produce stronger results than early morning or late afternoon sends.

Sender’s profile completeness

Your InMail is only as credible as your profile. LinkedIn’s research has shown that InMails from senders with complete, professional profiles — including a professional headshot, a detailed summary, recent work history, and recommendations — generate meaningfully higher response rates than those from sparse or incomplete profiles. When a recipient receives your InMail, the first thing many of them do is click through to your profile. If it looks incomplete or untrustworthy, your message is unlikely to get a reply regardless of how well it is written.

What kills response rates (and how to avoid it)

Several patterns consistently destroy InMail performance:

• Pitching in the first message. Leading with a product pitch, a pricing conversation, or a demo request before establishing any context or connection signals low-quality outreach and is the fastest way to be ignored or declined.
• Generic openers. Phrases like “I hope this message finds you well,” “I came across your profile,” or “I wanted to reach out because…” are recognised as templated outreach and reduce perceived personalisation.
• Making the message about yourself. InMails that spend most of their words on your company, your product, or your credentials without connecting to something relevant to the recipient consistently underperform those that lead with the recipient’s world.
• Vague calls to action. Ending with “Let me know if you’d like to chat sometime” gives the recipient nothing specific to respond to. A vague CTA produces a vague response — which usually means no response.

How to Write a LinkedIn InMail Subject Line That Gets Opened

The subject line is the first thing your recipient sees, and it determines whether they open your message or scroll past it. Most InMail subject lines are forgettable because they are written from the sender’s perspective rather than the recipient’s.

The role of the subject line (and why most fail)

A subject line does one job: it needs to make the recipient curious or confident enough to open the message. It is not a headline for your pitch. It is not a summary of what you are asking for. It is a hook — something that makes the reader feel like opening this particular message is worth their limited attention.

Most subject lines fail because they are either too generic (“Quick question”), too presumptuous (“Partnership opportunity”), or too sales-like (“Grow your revenue with X”). Each of these signals to the recipient exactly what kind of message follows, and none of them make the reader feel that what follows is for them specifically.

Subject line formulas that work

Mutual connection or shared context

Referencing something genuinely shared — a mutual connection, a group you are both members of, an event you both attended — immediately establishes common ground and reduces the social distance of a cold message.

Examples:

• “Both in the [Group Name] community”
• “[Mutual connection’s name] thought we should connect”
• “Met briefly at [Event Name] last week”

Specific observation about their work

Referencing something real and specific about the recipient’s work demonstrates that you have done your research and are not blasting a template to hundreds of people. This is the highest-trust subject line type, and it requires genuine preparation.

Examples:

• “Your piece on enterprise sales cycles”
• “Congrats on the [Company] Series B”
• “Noticed your team is expanding into APAC”

Role-relevant question

A question tailored to the recipient’s role or challenge can be effective when it signals that the answer in your message is worth reading. The question should be one the recipient actually cares about — not a rhetorical setup for your pitch.

Examples:

• “How is your team handling the new [industry regulation]?”
• “Is [specific challenge] still the biggest headache in your pipeline?”

Subject lines to avoid

• “Quick question” — overused to the point of being meaningless and widely associated with templated outreach
• “Opportunity for [Company Name]” — framed entirely around your interests, not theirs
• “Following up” — only appropriate for a genuine follow-up, and even then it is weak
• “Touching base” — no information value whatsoever
• Your company name in the subject — leads with brand when it should lead with relevance

Examples: weak vs. strong subject lines (side-by-side)

Weak	Strong
“Quick question”	“Your Q3 hiring push at Acme”
“Opportunity for your team”	“Noticed your team just expanded into fintech”
“Partnership inquiry”	“Both speakers at [Conference] last month”
“Checking in”	“How are you handling the new compliance requirements?”
“I’d love to connect”	“[Mutual contact] suggested I reach out”

The pattern in every strong example: specificity, recipient focus, and genuine context.

How to Write the InMail Body: Structure and Principles

A good subject line gets your message opened. A well-structured message body earns the reply. The body of an InMail needs to do several things at once — establish who you are, explain why you are writing to this person specifically, offer something of value, and make it easy for the reader to respond — all in under 400 characters if possible.

The anatomy of a high-performing InMail

Hook (first line)

The first line of your message body is the most important. In many inbox views, it is visible as a preview without the reader even opening the message. It should not begin with “My name is…” or “I’m reaching out because…” — these are generic openers that immediately signal a template. Instead, the first line should reference something specific and relevant to the recipient.

Good first lines start with them, not you: “Saw your post on the evolving role of AI in clinical trials — a perspective I don’t see often enough.” This immediately signals that the message is personal, not mass-produced.

Context / credibility

After the hook, briefly establish who you are and why you are relevant to the person you are writing to. This does not mean listing your credentials — it means providing enough context for the recipient to understand why this message is coming from you specifically. One to two sentences is sufficient.

Value to them (not you)

This is where most InMails fall apart. The body should articulate something of genuine value to the recipient — a resource, an insight, an introduction, a solution to a problem they are known to face. The value should be connected to something real about them, not a generic statement about what your company does. If you cannot identify what value you are offering the specific person you are writing to, you are not ready to send the InMail.

Soft, specific CTA

End with a single, low-friction call to action. “Would a 15-minute call on Thursday make sense?” is better than “Let me know if you’d like to chat.” A specific ask is easier to act on — and easier to decline, which is also acceptable because a decline gets your credit back.

Length: how short is too short, how long is too long

Based on LinkedIn’s own published performance data, InMails of 400 characters or fewer tend to outperform longer ones. In word count terms, that translates to roughly 60 to 80 words. A message that short forces you to be precise about every sentence. Too short, however — a single sentence with no context — does not give the recipient enough information to evaluate whether to reply.

The practical sweet spot is 60 to 100 words: long enough to be coherent and specific, short enough to be read without effort.

Personalization that goes beyond {{First Name}}

Inserting a first name into a template is not personalisation — it is automation. Real personalisation means referencing something specific to the individual:

• A piece of content they published or shared
• A recent career move or company milestone
• A challenge specific to their industry, role, or company stage
• A shared connection, event, or community
• A specific aspect of their company’s publicly visible work or strategy

Each of these requires research. They cannot be generated in bulk without degrading in quality. The trade-off is intentional: fewer, better InMails consistently outperform more, generic ones.

How to sound human, not like a template

Templates are useful as frameworks, not as finished messages. The difference between a message that reads as genuine and one that reads as a template often comes down to a few specific signals:

• Vary sentence rhythm. Templates tend to have a mechanical cadence — every sentence is roughly the same length. Human writing is uneven.
• Avoid qualifiers. Phrases like “I was hoping to,” “I wanted to reach out to,” and “I thought you might be interested in” are hedging language that dilutes confidence.
• Use their language. If their LinkedIn profile or recent posts use specific terminology, reflect it back in your message. It demonstrates genuine familiarity.
• Do not end with pressure. “I look forward to hearing from you” is a soft demand. A genuine question is warmer and less presumptuous.

InMail Templates for Different Use Cases

Templates are starting points. Every template below should be treated as a structural guide — not a message to copy and paste without modification. The placeholders in brackets represent the research you are expected to do before sending.

Sales prospecting InMail template

Subject: [Specific observation about their company or role]

Hi [First Name],

[One specific observation about their company, a challenge their industry faces, or something from their recent activity on LinkedIn.]

At [Your Company], we’ve helped [similar company type] [specific outcome — e.g., reduce onboarding time by 30%]. Given what you’re building at [Their Company], I thought it might be relevant.

Worth a 15-minute call to explore whether there’s a fit?

[Your Name]

Why this works: The opener is specific, the value claim is concrete, and the ask is low-friction and time-bounded.

Recruiter outreach InMail template

Subject: [Their role or area of expertise] opportunity at [Your Company]

Hi [First Name],

I came across your background in [specific skill or domain] and your work at [Their Current Company] — particularly [specific project or responsibility from their profile or public work].

We’re building out our [team/function] at [Your Company] and the role I’m thinking of could be a strong fit. It’s [brief description — two sentences max].

Would you be open to a 20-minute conversation to hear more, even if you’re not actively looking?

[Your Name]

Why this works: It demonstrates genuine profile review, positions the opportunity without hard-selling it, and explicitly acknowledges they may not be job-hunting — which reduces the pressure of replying.

Partnership or collaboration InMail template

Subject: [Shared audience / overlapping work area]

Hi [First Name],

I’ve been following [Their Company]’s work in [specific area] — [one sentence noting something specific and genuine]. Your approach to [topic] aligns closely with what we’re doing at [Your Company].

We both serve [type of audience or customer], and I think there’s a real collaboration opportunity worth exploring — whether that’s a content partnership, a co-hosted event, or something else.

Open to a conversation?

[Your Name]

Why this works: Partnerships require mutual benefit. This template leads with acknowledgment of their work and frames the ask as exploratory rather than transactional.

Job seeker reaching out to a hiring manager

Subject: [Role title] role — background in [your specific skill or domain]

Hi [First Name],

I noticed [Company Name] is hiring for a [Role Title] on your team. I’ve spent [X years] working on [specific relevant area], most recently [brief achievement relevant to the role].

I’d love to learn more about what success looks like in this role from your perspective — and happy to share more about my background if it seems like a potential fit.

[Your Name]

Why this works: It demonstrates initiative, references a specific role (not a generic interest), and frames the ask as a conversation rather than a plea.

How to adapt any template — avoid copy-paste syndrome

Every template above will degrade in quality the moment it is sent without modification. Before sending any InMail, go through this checklist:

• Does the subject line reference something specific to this person?
• Does the first line demonstrate that you know something real about them?
• Is the value you are offering connected to something specific about their role, company, or situation?
• Is the CTA low-friction and time-specific?
• Does the message read like it was written by a person, not generated from a formula?

If the answer to any of those questions is no, revise before sending.

How to Send an InMail on LinkedIn (Step-by-Step)

Sending an InMail is straightforward, but the exact steps vary depending on which LinkedIn product you are using.

From a profile page

• Navigate to the profile of the person you want to message
• If you are not connected and they are reachable via InMail, you will see a “Message” button (on Premium accounts) or an “InMail” option
• Click the button to open the InMail composer
• Add your subject line (up to 200 characters) in the subject field
• Write your message in the body (up to 1,900 characters)
• Review your message and click “Send”
• One InMail credit is deducted immediately upon sending — you cannot unsend an InMail after it has been delivered

From Sales Navigator

• Conduct a Lead or Account search in Sales Navigator
• Click on a lead’s name to open their Lead page
• Click the “InMail” button at the top of the lead record
• The InMail composer will open with the same subject line and body fields
• Sales Navigator allows you to save and reuse InMail templates directly within the platform — navigate to “Templates” in your settings to manage them
• Send as above; the credit is deducted from your Sales Navigator credit pool, not your standard LinkedIn Premium credits

From Recruiter

• Use Recruiter’s search to find a candidate
• Open the candidate’s profile within Recruiter
• Click “Send InMail” from the candidate’s profile
• Recruiter provides additional fields specific to recruiting contexts, including the ability to tag InMails to a specific project or pipeline
• Recruiter also supports bulk InMail sending to multiple candidates simultaneously, though LinkedIn strongly recommends against copy-paste bulk messages for response rate reasons

Can you schedule InMails?

As of the current version of LinkedIn’s products, LinkedIn does not offer native InMail scheduling from within the standard interface or Sales Navigator. Sending must be done manually in real time, which makes timing — specifically choosing mid-week, mid-morning send windows — a deliberate manual decision rather than an automated one.

After Sending: Tracking and Follow-Up

Sending an InMail is the beginning of a conversation attempt, not the end of your responsibility. What happens after you send — and how you respond to it — matters as much as the message itself.

Can you see if someone read your InMail?

LinkedIn does provide read receipts for InMail, but their availability depends on both parties’ privacy settings. If the recipient has read receipts enabled, you will see a small “Seen” indicator below your message, along with a timestamp. If the recipient has turned off read receipts in their privacy settings, you will not receive this confirmation. The absence of a read receipt does not mean the message was not delivered — it simply means their settings prevent the data from being shared.

What happens when someone declines your InMail

When a recipient clicks “Not interested” or “Decline,” you will receive a notification that your InMail was declined. Critically, LinkedIn refunds your InMail credit when this happens — a decline is treated as a response, and the credit policy rewards any outcome other than complete silence. You cannot send another InMail to the same person immediately after a decline — LinkedIn restricts follow-up outreach to people who have explicitly declined to avoid harassment.

What “awaiting response” means

“Awaiting response” is the status an InMail carries from the moment it is delivered until the recipient either replies or declines. An InMail can sit in “awaiting response” status for up to 90 days. If no action is taken within that window, the credit is forfeited and the InMail expires. “Awaiting response” is not the same as “read” — it simply means the message has been delivered and no explicit response has occurred yet.

Should you follow up — and how?

Following up on an InMail is appropriate, but it requires judgment. A single, well-timed follow-up is generally acceptable. Multiple follow-ups become harassment and will damage your reputation on the platform.

Follow-up timing

If your InMail has been read (visible via read receipt) but not replied to, wait five to seven business days before following up. If read receipts are not visible, waiting seven to ten days is a reasonable baseline. Following up the day after sending signals impatience and reduces the perceived thoughtfulness of your outreach.

Follow-up message example

A follow-up should be brief, should not repeat the original pitch verbatim, and should offer a new angle or simply acknowledge that you understand they are busy:

Hi [First Name], just wanted to resurface my earlier message in case it got buried. Happy to send across [a relevant resource / one-page overview / a few case studies] if that would make the decision easier. No pressure either way.

[Your Name]

This is approximately 45 words. It does not re-pitch. It offers something new (a resource) and explicitly removes pressure — both of which make it easier to respond to.

When to cut your losses and move on

If an InMail receives no reply after your initial message and one follow-up, and if there is no read receipt indicating the message was even opened, the probability of a response drops sharply with additional attempts. At that point, it is worth considering:

• Whether a different channel (email, a connection request, a mutual introduction) might be more effective
• Whether the timing was wrong and a future touch makes sense in three to six months
• Whether this particular person is genuinely a fit for your outreach, or whether your credit is better spent elsewhere

Persistence is a virtue in outreach; harassment is not. Knowing the difference is what separates effective outreach from damaged reputation.

InMail for Lead Generation: Making It Part of a Sequence

InMail works best when it is one deliberately placed touchpoint in a broader outreach strategy, not a standalone channel. Used in isolation, it is limited by credit caps and response rate ceilings. Used as part of a coordinated sequence, it becomes significantly more powerful.

InMail as one touchpoint, not your whole strategy

High-performing sales and recruiting professionals treat InMail as a precision instrument rather than a broadcast medium. Because credits are finite, each InMail should target a prospect who has already been qualified through research. Using InMail to reach the highest-value prospects in a list — while using email, content engagement, or other channels for broader reach — makes the credit investment go further.

InMail + connection request sequences

A common and effective sequence runs as follows:

• Touch 1: Send a personalised connection request with a note. This costs nothing and establishes a signal of interest.
• Touch 2: If the connection request is not accepted within 7 to 10 days, send an InMail to the same prospect. The connection request has primed them to recognise your name; the InMail now delivers the full message.
• Touch 3: If the InMail goes unanswered after a follow-up, consider whether a mutual introduction through a shared connection is feasible.

This sequence maximises the value of each credit by ensuring InMail is not the first cold touch — it is the escalation after a lower-friction approach has already been tried.

InMail + email multi-channel approach

For prospects who are identifiable across both LinkedIn and email, combining InMail with a coordinated email sequence increases overall reply rates. Research from outreach platform studies suggests that multi-channel sequences — where prospects are touched through two or more channels in a coordinated way — outperform single-channel outreach by a significant margin. The channels reinforce each other: a recipient who sees your name in both their email and their LinkedIn inbox perceives you as more serious and more credible than someone who appears in only one place.

How to use Sales Navigator search to target InMails precisely

Sales Navigator’s advanced search filters allow you to identify prospects with extraordinary precision before spending a single credit. Filters worth using include:

• Seniority level — target decision-makers appropriate to your ask
• Function and department — reach specific teams rather than entire companies
• Company size and growth rate — segment by firmographic relevance
• Recent job changes — people who have recently changed roles are often in buying or building mode
• Open Profile filter — identify prospects you can message for free before spending credits on those who require InMail
• Shared experiences — filter for people who attended the same school or worked at the same previous company, enabling stronger personalisation

Using these filters before building your InMail list means every credit is spent on a genuinely qualified prospect — which directly improves response rates and ROI.

How to Get More InMail Credits

Running out of InMail credits before the end of the month is a common frustration for active LinkedIn users. There are four distinct ways to extend your effective InMail reach.

Earn credits back through replies

The single most cost-effective way to increase your usable InMail credits is to improve your response rate. Every reply — including a decline — returns a credit to your account. A sender who gets a 40 percent reply rate effectively stretches 50 credits into the equivalent of roughly 83 contacts over time (as replied credits are recycled). Writing better InMails is not just good outreach practice; it is also a credit efficiency strategy.

Purchase additional credits

LinkedIn allows Premium members to purchase InMail credits beyond their monthly allocation. These are available through the Premium account management interface. Purchased credits have the same refund policy as subscription credits — a reply returns the credit. Before purchasing, it is worth examining whether your existing InMails are performing well enough to justify the additional spend. If your response rate is below 10 percent, more credits will not fix the underlying problem.

Use Open Profiles to send free InMails

As described in Section 2, messaging LinkedIn members who have enabled Open Profile status costs zero credits. Before spending credits on any outreach list, run a check — particularly in Sales Navigator, which has a built-in Open Profile filter — to identify members who can be messaged for free. Depending on your target audience, a meaningful percentage of your prospect list may qualify, effectively extending your credit budget.

When upgrading your plan makes financial sense

Upgrading from LinkedIn Premium Career (5 credits) to Premium Business (15 credits), or from Business to Sales Navigator (50 credits), makes financial sense when:

• You are consistently exhausting your credit allocation before renewal
• The value of conversations being initiated through InMail exceeds the incremental subscription cost
• Your outreach quality is already strong — response rates above 15 to 20 percent — so additional credits will generate proportionally more replies

Upgrading without first improving message quality is a common mistake. The higher credit allocation does not improve performance; better writing does.

Conclusion

LinkedIn InMail is a powerful tool when used with precision and care. It offers something genuinely rare in digital outreach — direct, professional access to virtually any LinkedIn member, with a built-in context that signals intentionality. But that access comes with constraints: limited credits, character limits, declining response rates, and a recipient base that is increasingly sophisticated about what good outreach looks like versus what lazy outreach looks like.

The difference between InMail that works and InMail that wastes credits comes down almost entirely to the quality of the message. Understanding the mechanics — how credits work, when they are refunded, what the character limits allow — is the foundation. But the actual results come from writing subject lines that earn an open, building message bodies that lead with the recipient’s world rather than your own, and making calls to action specific enough to act on. Templates provide structure; research and genuine personalisation provide the substance that turns structure into a reply.

Used as part of a coordinated outreach sequence rather than a standalone channel, and written with the care that a finite credit budget demands, InMail can consistently outperform other cold outreach methods. The senders who get the most from it are not the ones with the most credits — they are the ones who treat every message as if it costs something worth getting right.

Frequently Asked Questions

What is the difference between InMail and a LinkedIn message?

A regular LinkedIn message can only be sent to people in your first-degree network — people who have already connected with you. InMail can be sent to any LinkedIn member regardless of connection status, as long as you have the credits and the recipient’s privacy settings allow it. InMail also has a subject line field, which standard messages do not.

Is LinkedIn InMail worth it?

It depends on your use case and your message quality. For high-value, targeted outreach to people outside your network — senior candidates, key prospects, strategic partners — InMail is often the most direct path available. For volume outreach to a broad audience, email is typically more cost-effective. InMail is worth it when the quality of your messages is high and the targets are genuinely qualified.

Does LinkedIn InMail go to email?

Yes. LinkedIn sends an email notification to the recipient’s registered email address when they receive an InMail, unless the recipient has turned off email notifications in their LinkedIn settings. This means a well-timed InMail may be seen both in the LinkedIn app and in the recipient’s email inbox — effectively a dual-channel touch from a single send.

Do recruiters actually respond to InMail?

Recruiters tend to be more responsive to InMail than many other professional groups because their role involves reviewing candidate outreach. However, response rates vary significantly based on the relevance of the message. A recruiter receiving an InMail from a candidate whose skills closely match an open role they are actively working is far more likely to respond than one receiving a generic message from a candidate whose profile is not aligned with their current mandates.

Is it better to send an InMail or a connection request?

A connection request costs nothing and, if accepted, opens a free messaging channel. For most outreach scenarios, starting with a connection request and reserving InMail for cases where it goes unanswered is the most credit-efficient approach. InMail is the better choice when speed matters, when the message requires more space than a 300-character note allows, or when the prospect is very senior and unlikely to accept an unsolicited connection from a stranger.

What is the average InMail response rate?

LinkedIn’s own research suggests InMail generates approximately 3 times the response rate of a comparable cold email. In absolute terms, independent outreach research places the average InMail response rate between 10 and 25 percent, with personalised, well-targeted InMails from experienced senders reaching 30 percent or above. Response rates vary significantly by industry, seniority of target, and quality of the message.

Can you tell if someone declined your InMail?

Yes. LinkedIn sends a notification when a recipient actively declines your InMail. You will see the status update in your sent InMail history. When a decline occurs, your credit is automatically refunded.

How do I reply when a recruiter sends me an InMail?

If the opportunity is of interest, reply promptly and briefly — confirm your interest, offer your availability for a call, and attach or reference your updated CV or LinkedIn profile. If you are not interested, a polite, brief decline is courteous and also helps the recruiter get their credit back. You might write: “Thank you for reaching out — I’m not actively exploring opportunities right now, but I appreciate you thinking of me.”

Why do I only have 5 InMail credits?

Five credits per month is the allocation for LinkedIn Premium Career — the entry-level Premium tier. Career is designed for job seekers making targeted outreach, not for sales or recruiting at scale. If you need more credits for regular professional outreach, upgrading to Premium Business (15 credits), Sales Navigator (50 credits), or Recruiter Lite (30 credits) provides a proportionally larger monthly allocation.

What does “awaiting response” mean on an InMail?

“Awaiting response” is the status LinkedIn assigns to a sent InMail that has been delivered but not yet replied to or declined by the recipient. This status can remain for up to 90 days. It does not indicate that the message has been read — it simply means the system is waiting for an explicit action. If no action is taken within 90 days, the InMail expires and the credit is not refunded.

Can you send InMails without a Premium account?

You cannot send paid InMail without a Premium subscription. However, you can message any LinkedIn member who has enabled Open Profile status for free, regardless of whether you have a Premium account. This is the only way to send InMail-equivalent messages without a subscription. Standard LinkedIn members can also reach out via connection requests, which are free.

What happens to InMail credits I don’t use?

Unused InMail credits roll over from month to month, but only up to a maximum cap — typically up to 150 credits for most plans. Once you reach the cap, any further unused credits are forfeited and do not accumulate. If you regularly have unused credits at renewal, it is worth either reducing your subscription tier or increasing the quality and quantity of your outreach to put those credits to work.
