Short answer
A good LinkedIn InMail has a short, specific subject line and a body of about 100 words: why you're writing to this person now, who you are in one line, one useful idea, and a question they can answer in a sentence. LinkedIn allows up to 1,900 characters in Sales Navigator and Recruiter, but shorter messages get answered, and every InMail answered within 90 days returns your credit.
- Sales Navigator and Recruiter allow a 200-character subject and a 1,900-character body; LinkedIn's own sales blog suggests about 500 characters.
- Sales Navigator gives 50 InMail credits a month; Premium Career gives 5 and Premium Business 15.
- A response within 90 days returns the credit, and on Premium and Recruiter a decline counts too, so make no an easy answer.
- Open with a reason you're writing to this person now, not with your title or company history.
- Recruiter seats with a response rate under 13% over 14 days get a warning from LinkedIn.

This page is for sellers, recruiters, founders and job seekers who send LinkedIn InMail: the paid message that reaches someone you aren't connected to. It covers the limits and credit rules from LinkedIn's own help pages, what a good InMail looks like, nine templates by situation and a worked example with the credit arithmetic. If you're writing a connection request instead, the LinkedIn connection message examples cover the 200-character note.
InMail, connection note or email?
Pick the channel before you write. Each one has different limits and a different job.
| Channel | Who you can reach | Length | Cost | Best for |
|---|---|---|---|---|
| InMail | Any member, without connecting | 200-character subject, 1,900-character body (Sales Navigator, Recruiter) | One credit, returned if they respond within 90 days | A senior person you can't easily connect with, when you have a specific reason |
| Connection request note | Anyone you invite | 200 characters | Free, but free accounts get only a few notes a month | Starting a relationship you'll build over weeks |
| Message to an Open Profile member | Premium members who turned on Open Profile | Same as a message | No credit | Anyone whose profile shows the Open Profile option |
| Anyone with a known address | No practical limit | Free to send | A longer case, attachments, or a follow-up after a call |
InMail reaches someone without a connection, but it costs a credit, so spend it where you have a specific reason to write.
The limits and credit rules, from LinkedIn's help pages
LinkedIn's help pages don't all agree, so plan around the stricter number.
| Rule | What LinkedIn says | What it means for you |
|---|---|---|
| Subject line | Up to 200 characters; "required" in Sales Navigator | Always write one, and keep it short enough to read on a phone |
| Body | Up to 1,900 characters (Sales Navigator and Recruiter help); the general InMail FAQ says 2,000 | Write well under 1,900. LinkedIn's sales blog suggests a maximum of 500 characters, about 100 words |
| Premium credits | Premium Career: 5 a month, up to 15 held. Premium Business: 15 a month, up to 45 held | Credits renew on the first day of your billing cycle and drop to zero if you cancel |
| Sales Navigator credits | 50 a month, up to 150 held; unused credits carry over and "must be used within 90 days" | Renewed on the first of each month (UTC) |
| Recruiter credits | Set by your contract and your admin's limits | Ask your admin for the monthly number |
| Credit back | Premium and Recruiter: a credit returns if the InMail is accepted, declined or replied to within 90 days. Sales Navigator: if it "receives a response within 90 days" | A pending message earns nothing back; a polite no does |
| Recruiter response rate | Under 13% over 14 days brings a warning; a repeat breach may mean an "InMail Improvement Period" | Recruiters especially can't afford mass, untargeted InMail |
| Reminder | Sales Navigator sends the recipient an automatic reminder within three days | Don't follow up before day four |
The credit-back rule matters most. A message that gets a reply, an acceptance or (on Premium and Recruiter) a decline costs you nothing, so the templates below end with a question that's easy to answer either way.
What makes an InMail get answered
Every template on this page has the same five parts:
- A subject that names their situation. "Power for the new Reno site" beats "Quick question" or "Partnership opportunity". It tells them the message is about them before they open it.
- Why you're writing to them now. One specific, checked fact from their profile or their company: a new role, a new site, a post, a hire. This is the line that separates an InMail from a mass message.
- Who you are, in one line. Your company and what it does for people like them. No title, no history, no client list.
- One useful idea or offer. A resource, an estimate, an observation. Something they'd value even if they never buy.
- A question they can answer in a sentence. Including "no". Give them an easy way out, because a decline still returns your credit and tells you something.
LinkedIn's Recruiter help page on effective InMail says "simpler and more direct" messages get more responses, and tells recruiters not to paste a job description or job post link. The same logic applies to sales: don't paste your brochure.
LinkedIn InMail templates by situation
Fill in the brackets and cut anything that doesn't serve the five parts. Each body stays under 500 characters filled in.
Subject: [the event, e.g. The new Reno site] Hi [first name], I saw [company] [the event, e.g. broke ground on a site in Reno] in [month]. When [type of company] does that, [role]s usually end up dealing with [the problem it creates]. I'm with [your company]. We help [type of company] with [outcome]. [Offer, e.g. I can send a one-page estimate for the new site.] Is [area] on your list right now, or already settled? [Your name]
Subject: Your first months at [company] Hi [first name], congratulations on the move to [company]. New [role]s often spend their first quarter deciding what to keep and what to change in [area]. If [problem] is on that list, I may have something useful: [resource or idea]. I'm at [your company], where we [what you do for people in their role]. Would it help if I sent it over, or is [area] not a priority yet?
Subject: [number] [role] openings at [company] Hi [first name], I noticed [company] is hiring [number] [role]s. Teams usually do that when [what it suggests, e.g. order volume has outgrown the current process]. At [your company], we help [type of company] [handle that growth / get new hires productive faster]. How are you planning to [the challenge] while the new team ramps up?
Subject: Your post on [topic] Hi [first name], Your post on [topic] made a point I don't see often: [the specific point, in a few words]. I work on the same problem from the [your side] side at [your company]. One thing we've seen is [a short, relevant observation]. Is that matching what you see at [company], or is it different for [their type of business]?
Subject: [Mutual contact] suggested I write Hi [first name], [Mutual contact] suggested I get in touch. We were talking about [topic], and [she/he/they] said you look after [area] at [company]. I'm with [your company]; we help [type of company] with [outcome]. [Mutual contact] thought [specific reason] might be relevant. Would a short call next week be useful, or is there someone better placed?
Subject: A question about [area] at [company] Hi [first name], A question I've been asking [role]s at [type of company]: [specific question, e.g. how do you compare print costs across your 40 branches?] Most tell me [common answer], which usually means [consequence]. I'm with [your company], and we [what you do]. Is that true for [company] too? If not, a one-word "no" is fine and I won't follow up.
Subject: Re: [original subject] Hi [first name], One more note, then I'll leave it. Since my last message, [something new: a relevant result, news at their company, a resource]. If [area] isn't a priority, no reply needed. If it is, [small, specific offer].
Subject: Your [specific work] at [current company] Hi [first name], Your [specific project or experience, e.g. rollout of the warehouse system across six sites] is the kind of work our [team] is doing next. I'm recruiting a [role] at [company] in [location or remote]. The short version: [one line on scope and why it's interesting]. Would you be open to a 15-minute call to hear more? If now isn't the time, I'd value knowing what would make a move worth it for you.
Subject: [Role] opening and my [relevant experience] Hi [first name], I applied for the [role] on your team and wanted to add one thing the application doesn't show: [specific result, e.g. I cut monthly reporting time from three days to one at my last company]. I'd value 15 minutes to learn what matters most in the role. Would that be possible in the next couple of weeks?
Worked example: one InMail and the credit arithmetic
Illustrative example. The companies, people and figures are fictional, to show the method.
The seller: Sam, a business development rep at Brightfield Solar Builders (brightfield.example), a solar EPC firm that designs and builds rooftop solar for commercial buildings. Sam has Sales Navigator: 50 credits a month.
The account: Kessler Cold Storage (kesslercold.example), which broke ground on a refrigerated warehouse in Reno in September. The person: Dana, the Director of Facilities, who isn't connected to anyone on Sam's team.
The first draft (130 words, 864 characters), opening and close:
Hi Dana, I hope this message finds you well! My name is Sam and I'm a Senior Business Development Representative at Brightfield Solar Builders, a leading full-service commercial solar EPC with over 15 years of experience... [three sentences of services and client types] ...I would love to set up a 30-minute call next week to walk you through our capabilities.
The rewrite (82 words, 481 characters), subject "Power for the new Reno site":
Hi Dana,
I saw Kessler Cold Storage broke ground on its Reno site in September. Cold storage runs compressors around the clock, so I'd guess power is one of the bigger costs you're planning for.
I'm with Brightfield Solar Builders. We design and build rooftop solar for warehouses and cold storage.
I can send a one-page estimate of what the new roof could produce. Is energy on your list for Reno, or already settled? Either answer helps.
Sam Ortiz, Brightfield Solar Builders
| First draft | Rewrite | |
|---|---|---|
| Opens with | Sam's name and title | Dana's new site |
| Reason for writing now | None | The September groundbreaking |
| About Brightfield | Four sentences | One sentence |
| The ask | A 30-minute call | A yes-or-no question and a free estimate |
| Easy to decline | No | Yes ("either answer helps") |
The credit arithmetic. Because a response returns the credit, the share of InMails that get answered decides how many you can really send. With 50 credits a month and every response landing within the 90-day window:
| Response rate (illustrative) | Credits returned per 50 sent | InMails 50 credits can fund (50 ÷ (1 − rate)) |
|---|---|---|
| 10% | 5 | about 55 |
| 20% | 10 | about 62 |
| 30% | 15 | about 71 |
At a 30% response rate, the same seat sends about 16 more InMails a month than at 10%. On Premium Business, where a decline also returns the credit, a print management company's account manager with 15 credits and 40% of recipients accepting or declining could fund 25 InMails a month (15 ÷ 0.6).
The research behind the second line is the slow part when the list runs to 50 accounts. Bebop researches each account and writes a playbook with who to talk to, what's happening at the company and the angle to open with, so each InMail starts from a real reason. Check the facts it gives you before you send.
Measuring your InMail
Track two numbers per template over at least 30 sends before you judge it: the response rate (replies, acceptances and declines divided by InMails sent), which sets your credit cost, and the positive reply rate (replies that agree to talk or ask for more), which sets your pipeline. A low response rate points at the subject and first line; a low positive rate with a healthy response rate points at the offer. On Recruiter, LinkedIn's 13% warning level over 14 days is a floor, not a target. For wider LinkedIn figures traced to their sources, see the LinkedIn statistics.
Mistakes to avoid
- Writing to the limit. 1,900 characters is the ceiling, not the goal. A wall of text on a phone screen gets archived.
- Leading with yourself. Your name and title are already next to the message. The first line should be about them.
- A big ask. A 30-minute call is a lot to ask a stranger. Ask a question, or offer something small.
- Claiming a referral you don't have. Name a mutual connection only if they agreed to it.
- Automation. LinkedIn's User Agreement bans "bots or other unauthorized automated methods" for sending messages. Write and send InMail yourself.
- Following up too soon. Sales Navigator already reminds the recipient within three days. Wait a week, send one follow-up with something new, and stop.
Checklist before you send
- The subject line names their situation, not your product.
- The first sentence gives a specific, checked reason you're writing to them now.
- Your company gets one sentence.
- The body is under 500 characters, about 100 words.
- There's one offer or idea they'd value even if they never buy.
- It ends with a question they can answer in a sentence, including "no".
- Any mutual connection you name has agreed to it.
- You've checked whether they have an Open Profile, which you can message without a credit.
Next step: InMail is one channel in a LinkedIn plan. The LinkedIn lead generation guide shows how to combine profile, connection requests, InMail and follow-up into a weekly routine.

Questions people ask
What is a LinkedIn InMail?
InMail is LinkedIn's paid message for contacting a member you aren't connected to. It's included with Premium, Sales Navigator and Recruiter plans as a monthly allowance of credits: one credit per message. LinkedIn returns the credit when the recipient responds within 90 days. Messages to Premium members who have turned on Open Profile don't use a credit at all.
How long should a LinkedIn InMail be?
About 100 words, or roughly 500 characters, which is what LinkedIn's own sales blog recommends as a maximum. The technical limit is a 200-character subject and a 1,900-character body in Sales Navigator and Recruiter, but long messages are hard to read on a phone. Use the space for one reason you're writing, one line about you, one idea and one question.
How many InMails can I send per month?
It depends on your plan. LinkedIn's help pages list 5 credits a month for Premium Career (up to 15 held), 15 for Premium Business (up to 45) and 50 for Sales Navigator (up to 150). Recruiter allowances depend on your contract. Because responses return credits, a well-targeted seat can send more InMails than its allowance over a month.
Do you get InMail credits back?
Yes, when the recipient responds within 90 days of the send date. For Premium and Recruiter, LinkedIn counts an acceptance, a decline or a reply; Sales Navigator's help page says a credit returns for every InMail that receives a response within 90 days. Messages left pending earn nothing back, so end every InMail with a question that's easy to answer, even with no.
Is InMail better than a connection request?
They do different jobs. A connection request is free and starts a relationship, but its note is capped at 200 characters and the person must accept before you can message them. InMail reaches anyone straight away with room for a fuller message, but it costs a credit. Use InMail for senior people where you have a specific, timely reason to write.
Can I send InMail for free?
Sometimes. Premium members can turn on Open Profile, which LinkedIn says lets anyone message them for free without using InMail. Members on free accounts can send only a limited number of these messages each month. Otherwise, InMail needs a paid plan with credits: Premium, Sales Navigator or Recruiter. A credit you spend comes back if the recipient responds within 90 days.
