LinkedIn InMail: How It Works, Credits, Templates, and Best Practices

LinkedIn InMail lets you message anyone on the platform — even people you're not connected to. It's the primary outreach tool for recruiters, sales professionals, and anyone who needs to start conversations with people outside their network. But InMail credits aren't free, and most messages get ignored because they read like templates.

Here's how LinkedIn InMail works in 2026, how many credits you get, what a good InMail looks like, and when you should use alternatives instead.

What Is LinkedIn InMail?

InMail is LinkedIn's premium messaging feature that lets you send direct messages to any LinkedIn member, regardless of whether you're connected. Unlike regular LinkedIn messages (which require a 1st-degree connection), InMail bypasses the connection requirement entirely.

Key facts:

• Requires a premium LinkedIn subscription — InMail credits are not available on free accounts
• Each message costs one credit from your monthly allocation
• Credits are refunded if the recipient responds within 90 days
• Messages land in the recipient's LinkedIn inbox and generate an email notification
• Character limit: 200 characters for the subject line, 1,900 characters for the body

InMail messages are visually labeled as "InMail" in the recipient's inbox, so they know you're not a direct connection. This makes your first impression critical — the message needs to earn attention immediately.

How Many InMail Credits Do You Get?

Your monthly credit allocation depends on your LinkedIn subscription:

| Plan | Monthly InMail Credits | Price | |---|---|---| | Premium Career | 5 credits | ~$30/month | | Premium Business | 15 credits | ~$60/month | | Sales Navigator Core | 50 credits | ~$100/month | | Sales Navigator Advanced | 50 credits | ~$150/month | | Recruiter Lite | 30 credits | ~$170/month | | Recruiter Corporate | 150 credits | Custom pricing |

Credit Rollover Rules

• Unused credits roll over to the next month for up to 90 days
• Maximum accumulation is capped at 3x your monthly allotment (e.g., Sales Navigator users can accumulate up to 150 credits)
• Credits reset if you downgrade or cancel your subscription
• Refunded credits (from recipient responses) don't count toward the accumulation cap

Buying Additional Credits

You can purchase extra InMail credits at approximately $10 per credit. At that price, every InMail needs to count — which is why writing compelling messages matters more than volume.

How to Write an InMail That Gets Responses

The average InMail response rate is around 10–25%, but well-crafted messages can hit 40%+. Here's the difference between InMails that get responses and ones that get deleted.

Subject Line: Your Make-or-Break Moment

The subject line determines whether your InMail gets opened. Keep it under 10 words, specific, and personalized.

Good subject lines:

• "Quick question about your content strategy at [Company]"
• "Saw your talk on B2B growth — one idea"
• "[Mutual connection] suggested I reach out"

Bad subject lines:

• "Exciting opportunity!"
• "Let's connect"
• "I'd love to pick your brain"

Message Structure: The RABT Framework

The most effective InMail structure follows the RABT formula:

1. Reason — Why you're reaching out right now (reference something specific: a post they wrote, a role change, a company milestone)
2. Ask — Your specific, low-commitment request (a 15-minute call, a quick question, feedback on an idea)
3. Backup — Show you understand their world (mention a challenge they likely face, reference industry context)
4. Tease — Hint at the value you bring without a full pitch (a relevant insight, a result you achieved for a similar company)

Length: Shorter Wins

Data consistently shows that InMails under 400 characters outperform longer messages. Recipients are scanning, not reading essays. Get to the point in 3-4 sentences:

1. One sentence of personalized context
2. One sentence explaining why you're reaching out
3. One sentence with your specific ask
4. One sentence of social proof or value tease (optional)

Example InMail Templates

For Sales Outreach:

Hi [Name], I noticed [Company] just expanded into [market/region] — congrats on the growth. We helped [similar company] cut their outreach time by 40% during a similar expansion. Would a 15-minute call next week make sense to see if we could help?

For Networking:

Hi [Name], your post about [specific topic] really resonated — especially the point about [specific detail]. I'm working on something similar at [Company] and would love to swap notes. Open to a quick chat?

For Recruiting:

Hi [Name], I'm hiring a [role] at [Company] and your background in [specific skill] stood out. We're a [brief company description] and the role involves [one compelling detail]. Worth a conversation?

When to Use InMail vs. Alternatives

InMail isn't always the best option. Here's when to use it and when to choose something else:

Use InMail When:

• You can't connect directly — they're a 3rd-degree connection or out of network
• You need a professional context — LinkedIn InMail carries more credibility than cold email for B2B outreach
• Timing matters — InMails generate immediate email notifications, making them good for time-sensitive outreach
• You have a personalized, specific reason to reach out

Use Alternatives When:

• You can send a connection request instead — a well-written connection request message (300 characters) is free and often just as effective
• You have their email — a direct email avoids the "InMail" label and LinkedIn's interface
• You're reaching out to many people — InMail credits are too expensive for high-volume outreach
• They have "Open Profile" — Premium members with Open Profile enabled can receive free messages from anyone

The Connection Request Alternative

Before spending an InMail credit, check if a connection request with a note would work. Connection requests are free, and the 300-character note limit forces you to be concise. Many professionals accept well-written connection requests — especially if you reference shared interests, mutual connections, or their content.

The downside: connection requests can be ignored or declined with no notification, and you only get a limited number per week. InMail guarantees delivery to their inbox.

InMail Best Practices

1. Research Before You Write

Spend 2-3 minutes reviewing the recipient's profile, recent posts, and activity before writing. Reference something specific in your message — this is the single biggest factor in response rates. Generic InMails get generic results (silence).

2. Send at the Right Time

InMails sent on Tuesday through Thursday mornings get the highest response rates, mirroring the broader best times to post on LinkedIn. Avoid Friday afternoons and weekends.

3. Follow Up (Once)

If you don't get a response, send one follow-up after 5-7 business days. Keep it short: "Just bumping this up — let me know if the timing doesn't work and I'll check back later." More than one follow-up via InMail crosses into pushy territory.

4. Track Your Response Rates

LinkedIn provides InMail analytics showing your acceptance rate, response rate, and how you compare to benchmarks. Use this data to iterate on your messaging — if your response rate is below 15%, your messages need work.

5. Maximize Credit Efficiency

Since responded InMails refund your credit, focus on quality over quantity. Five well-researched, personalized InMails will generate more responses (and more refunded credits) than 20 generic blasts.

InMail vs. Sponsored InMail (Message Ads)

Don't confuse regular InMail with LinkedIn Message Ads (formerly Sponsored InMail). They're different products:

| Feature | Regular InMail | Message Ads | |---|---|---| | Sent from | Your personal profile | Your company page | | Targeting | You choose individual recipients | LinkedIn's ad targeting (job title, industry, etc.) | | Volume | Limited by credits | Limited by budget | | Cost | Part of premium subscription | Pay per send (~$0.50-$1.00 each) | | Personal feel | High (1-to-1 message) | Low (clearly an ad) | | Best for | Sales outreach, recruiting, networking | Lead generation campaigns, event promotion |

For one-to-one outreach, regular InMail wins. For reaching hundreds or thousands of targeted professionals, Message Ads are more scalable.

Key Takeaways

• LinkedIn InMail lets you message anyone on the platform, but requires a premium subscription (5–150 credits/month depending on plan)
• Credits are refunded when recipients respond within 90 days — quality messages literally pay for themselves
• Keep InMails under 400 characters with a personalized subject line and specific ask
• Use the RABT framework: Reason, Ask, Backup, Tease
• Before spending a credit, check if a free connection request with a note would work instead
• Track your response rates and iterate — aim for 25%+ to make the credit investment worthwhile
• Pair InMail outreach with strong personal branding — recipients will check your profile before responding
