LinkedIn InMail is a premium feature that lets you directly message anyone on the platform, even if you aren't connected. It's a direct line to a prospect's inbox, allowing you to bypass connection requests.
This makes InMail an essential tool for B2B sales, recruiting, and high-level networking. It’s designed for targeted, high-impact outreach, not for mass messaging.
Your VIP Pass to a Prospect's Inbox
Sending a connection request is like waiting in line at an event, hoping to get in. InMail is your VIP pass—it lets you walk right past the velvet rope to start a conversation with your ideal prospect.
A standard LinkedIn message is free but limited to your 1st-degree connections. InMail removes that barrier, giving you direct access to 2nd and 3rd-degree connections. For building new business relationships, this is a game-changer.
Why InMail Is a Strategic Tool
InMail signals importance. Recipients know it's a limited, paid resource, so they understand you've invested to contact them. This makes your message feel more significant and stand out from inbox noise.
This dynamic drives superior results. InMail response rates typically land between 10-25%, far outpacing the 1-5% average for cold email. Each InMail credit is a valuable asset for strategic outreach.
Best Practice: An InMail isn't just a message; it's a strategic move. It tells the recipient, "I specifically chose to use a limited credit to contact you," which immediately commands more attention.
Mastering InMail is a cornerstone of effective B2B lead generation on LinkedIn. The goal is not to spam but to craft thoughtful, relevant messages for high-value contacts who can genuinely impact your business. Used correctly, it’s one of the most effective ways to start conversations that lead to sales and partnerships.
How InMail Credits and Limits Work
LinkedIn InMail operates on a credit system tied to premium subscriptions like Sales Navigator. This system is designed to promote high-quality, relevant messages over spam.
Each month, your account receives a set number of InMail credits. For example, a Sales Navigator Core plan provides 50 credits per month. This scarcity forces you to be strategic about who you contact and why.
The purpose is to send a direct, targeted message that cuts through the noise.
As shown, InMail lets you bypass the need for a mutual connection, giving you a direct line to your target prospect.
Best Practice: Leverage the Credit Refund System
LinkedIn refunds your InMail credit if you receive a response within 90 days. Any reply—"yes," "no," or "not now"—gets you your credit back.
This system directly rewards effective outreach. If your message is compelling enough to start a conversation, you aren't penalized. You get to keep your credit and use it again, creating a positive feedback loop for high-quality messaging.
This feature separates professional outreach from simple message blasting. It’s not just about sending; it's about connecting.
How Unused Credits Work
Unused credits roll over to the next month, but there's a cap. For a plan with 50 monthly credits, you can accumulate a maximum of 150 credits. This encourages consistent use of the tool.
The single biggest advantage of InMail is its 100% deliverability rate. While cold emails risk getting caught in spam filters or bouncing, an InMail is guaranteed to arrive in your prospect's main LinkedIn inbox. Every time.
This reliability is critical for B2B sales. When you combine perfect delivery with a 10-25% response rate (compared to email's 1-5%), it’s clear why InMail is such a powerful channel. For more data, see the research on InMail performance benchmarks on salesso.com.
Understanding these mechanics is the first step toward building an outreach strategy where every message makes an impact.
Choosing Your Outreach Channel: InMail vs. Email
When conducting B2B outreach, the question isn't whether to use InMail or email. The most effective professionals build a multi-channel strategy where each tool serves a specific purpose.
Think of it like a toolbox: InMail is your precision instrument for high-value targets, while email is your versatile wrench for broader, scalable campaigns. The goal is to move beyond a one-size-fits-all approach and build a process that gets responses.
A Head-To-Head Comparison
To understand where each channel excels, let's compare them side-by-side. InMail, connection requests, and cold email each have unique strategic advantages.
Outreach Channel Comparison: InMail vs Connection Request vs Email
Feature | LinkedIn InMail | Connection Request | Cold Email |
Primary Goal | Direct, high-impact messaging to key decision-makers. | Building your professional network and warming up future leads. | Scalable outreach for lead generation and nurturing. |
Deliverability | Guaranteed delivery to the prospect's LinkedIn inbox. | High, but contingent on the person accepting the request. | Varies widely; can be blocked by spam filters. |
Message Length | Up to 1,900 characters for the body and 200 for the subject. | Limited to a short 300-character note. | Virtually unlimited, but shorter is almost always better. |
Perceived Value | High. The recipient knows you used a paid credit to contact them. | Moderate. It's a networking gesture, not a direct sales pitch. | Low. Often seen as spammy unless highly personalized. |
Best For | C-suite execs, Tier 1 accounts, and hard-to-reach prospects. | Industry peers, potential partners, and Tier 2/3 prospects. | Reaching large, well-defined audience segments. |
Reply Rate | Typically 10-25%. | Varies; the focus is on the connection, not the reply. | Averages a much lower 1-5%. |
As the table shows, there’s a clear time and place for each tool. Using the right one for the job is what makes an outreach campaign effective.
Why Context Matters
When targeting a C-suite executive who receives hundreds of emails daily, a generic message from one of those cold email templates is easily ignored. It becomes part of the noise.
This is where InMail excels. It cuts through the clutter because recipients know InMail credits are a limited, paid resource. This fact alone gives your message an inherent weight and signals that you’ve specifically invested in getting their attention.
The data supports this: LinkedIn InMail consistently achieves reply rates between 10-25%, crushing the typical 1-5% reply rate for cold email. A coordinated strategy combining email, InMail, and phone calls can boost overall effectiveness by 287%.
An Actionable Framework for Deciding
Here’s a simple framework to help you choose the right channel:
Use InMail for High-Value Targets. For key decision-makers on major deals, InMail's guaranteed deliverability and high perceived value make it the best choice for account-based sales.
Use Email for Scaled Campaigns. To reach a broader but well-defined audience, email is more efficient and cost-effective for nurturing a large pool of leads over time.
Use Connection Requests for Networking. This is a long-term play for building relationships with peers, partners, or future prospects you want to keep on your radar.

How to Write InMail Messages That Get Replies
Knowing InMail's mechanics is one thing; getting a reply is another. In a world of automated outreach, a thoughtful, human message stands out.
The goal is to start a conversation, not to force a sales pitch. This requires genuine personalization, respect for the recipient's time, and a clear, easy-to-answer question. A generic InMail is like a billboard—easily ignored. A personalized message is like a handwritten note—it’s compelling and hard to disregard.
Best Practices for High-Converting InMails
Effective InMails are concise messages that respect the recipient's time and spark curiosity. Each part of the message has a specific job.
Write a Short, Compelling Subject Line. Make your first impression count. Keep it brief and specific. Replace "Quick Question" with "Loved your post on AI in sales" or "Question about [Company]'s recent funding."
Use a Hyper-Personalized Opening. The first sentence is critical. Prove you've done your research. Reference a recent article, podcast appearance, or mutual connection to show you aren't sending a generic template.
Provide a Clear Value Prop (From Their Perspective). Don't talk about what your company does. Frame your solution in the context of a challenge or goal relevant to them.
Include a Low-Friction Call-to-Action (CTA). Avoid big asks like "schedule a 30-minute demo." Instead, use an interest-based question like, "Open to learning how we helped [Similar Company] solve this?" This makes it easy for them to say "yes" and start a conversation.
Actionable Tip: Research shows InMails under 400 characters have a 22% higher response rate. Brevity is a strategic advantage that demonstrates you value your prospect’s time.
Putting It All Together: An Actionable Example
Here’s a side-by-side comparison illustrating how small changes can transform your message's impact.
Do This (Effective Example) | Not That (Ineffective Example) |
Subject: Congrats on the Series A funding! | Subject: Intro: DexyAI |
Body: "Hi [Name], saw the great news about your recent funding round. The work your team is doing in the fintech space is impressive. We helped [Similar Company] scale their outbound by 3x after their Series A. Open to seeing how we did it?" | Body: "Hi, my name is Alex from DexyAI. We are a leading AI-powered outbound platform. I'd love to schedule a 30-minute demo to show you how our solution can revolutionize your sales process. Are you free Tuesday or Thursday?" |
The effective example is short, personalized, and ends with a simple question. It focuses on the recipient's success and offers value with a low-pressure ask. That’s the blueprint for turning cold outreach into warm conversations. For more strategies, check out other articles on our blog.
Proven InMail Templates You Can Use Today
Theory is useful, but actionable templates provide a starting point. Here are a few proven frameworks you can adapt for your own outreach.
Remember, these are not rigid scripts. The best results come from injecting your own research and personality into these structures.
The Common Ground Template
This template establishes an immediate human connection by referencing a shared experience or group, which instantly lowers a prospect's guard.
Subject: From a fellow [University/Group Name] member
Body: Hi [Name], I noticed we’re both part of the [Group Name] on LinkedIn and was impressed by your recent post on [Topic]. Your point about [Specific Insight] really resonated. At [Your Company], we're working on a similar challenge for companies like yours. Open to a quick chat about how we're approaching it?
The Company Announcement Template
Timing is critical. Reaching out after a major company announcement (funding, product launch, award) shows you've done your research and your message is timely.
Subject: Congrats on the [Announcement]!
Body: Hi [Name], I saw the news about [Company]'s recent [Funding Round/Product Launch]—congratulations. Scaling after a milestone like that often brings new challenges around [Relevant Pain Point]. We helped [Similar Company] navigate this phase and boost their [Specific Metric] by [Percentage]. Open to hearing how?
This template positions your solution as a relevant answer to a problem they are likely facing right now.
Best Practice: LinkedIn InMail is a top tool for sales development. Research shows 46.3% of SDR teams name it their second-most effective activity after prospect research. With 10-25% response rates, InMail turns cold outreach into conversations 2.6-5x faster than email’s 1-5%. You can explore these results by reviewing the State of Sales Development report.
The Concise Value Prop Template
When you can't find a shared connection or a recent trigger event, a direct, no-fluff value proposition is your best bet. This template is concise and respects their time.
Subject: Idea for improving [Their Business Area]
Body: Hi [Name], I’ve been following [Their Company] and was thinking about the challenges of [Specific Business Problem]. We help VPs of Sales like you solve this by [Your One-Sentence Solution], which led to a [Key Stat/Result] for [Client Name]. Is this on your radar right now?
The power of this template is its brevity. It is short, direct, and focused on a specific, high-impact result you can deliver.
Common InMail Mistakes That Kill Response Rates
Even a well-targeted InMail campaign can fail due to common mistakes. Understanding what causes a prospect to ignore your message is as important as knowing what to write.
The first mistake happens before you even send a message: having a weak or unprofessional LinkedIn profile. When a prospect gets your InMail, the first thing they do is click on your profile. If it’s outdated or fails to clearly articulate your value, you lose credibility instantly—and the chance of a reply.
Actionable Tip: Avoid Self-Centered Messaging
Another critical error is making the message all about you. Prospects don’t care about your company’s features; they care about what’s in it for them. Messages that overuse "I" and "we" come across as a sales pitch. Instead, focus on a problem you know they face.
Here are the top mistakes that will get your InMail archived:
Writing a Novel: Long paragraphs are overwhelming. Research shows that InMails under 400 characters get a 22% higher response rate. Keep your message short and scannable.
Using a Pushy Call-to-Action (CTA): Asking for a 30-minute demo in a first message is too aggressive. Start with a low-effort question to begin the conversation.
Sending a Generic Template: Recipients can spot a copy-paste message easily. Without genuine personalization—a reference to their work, a shared post, or a mutual connection—your InMail becomes more noise.
Best Practice: Effective outreach feels less like a sales pitch and more like the start of a conversation. Your goal isn't to close a deal in one message; it's to earn the right to a second interaction.
By avoiding these common traps, you shift from being just another cold pitch to a relevant professional. This change alone can significantly increase your response rates.
Your InMail Questions, Answered
Here are answers to the most common questions about using LinkedIn InMail for B2B outreach.
Is InMail Better Than Cold Email?
For high-value targets, yes. InMail offers 100% deliverability to a prospect's primary LinkedIn inbox. Its 10-25% response rate far exceeds the 1-5% average for cold email. While email is better for high-volume campaigns, InMail is the precision tool for account-based selling when you must reach a specific decision-maker.
What Happens When I Run Out of InMail Credits?
You must wait for your monthly billing cycle to reset. However, LinkedIn rewards effective outreach: if you get a response within 90 days, your credit is refunded. To stretch your credits, you can send free messages to "Open Profile" members or people in shared LinkedIn Groups.
Can I Automate Sending InMails?
LinkedIn's terms of service strictly forbid using most third-party automation tools for sending InMails. Violating these terms can lead to account suspension. LinkedIn wants to maintain the platform's focus on genuine, one-to-one conversations.
The best practice is not to use illicit bots but to leverage compliant tools that enhance manual outreach. AI-powered personalization can help you write better copy, and workflow systems can improve your efficiency without risking your account.
