LinkedIn InMail generator

An InMail is a message to someone outside your network, and your account gives you a limited number of them, so each one should deserve the send. From who they are, what you are asking for, and why you are credible, this writes a subject line that says what the message is about and a body short enough to be read to the end.

Fill in what you have. More context, better output.

Example run

A subject and message that respect the reader

Subject under 60 characters, message under 120 words, why-them in the first sentence, and an easy out in the last line. That is what gets InMails answered.

Your two senior backend roles

You have posted twice about senior backend hiring, so I will keep this short. I run a technical recruiting firm. Thirty of our last forty placements were senior backend engineers at healthcare companies, which is why your posts stood out. If the two roles are still open, I would like 20 minutes to explain how our contract-to-hire model works and whether it fits your team. If hiring is already covered, ignore this and good luck with the search.

Why it matters

InMail goes straight to the people who decide.

InMail lands without an introduction, so all the credibility has to live in the message itself and in the profile behind it. Short and specific is what survives that bar.

Beyond the demo

This page writes from a form. The product writes from you.

The generator above works with whatever fits in a few fields. Connect LinkedIn to Depost AI, the AI content team B2B founders and teams run on LinkedIn, and the same kind of draft starts from your analytics, your voice, and the buyers you are actually trying to reach.

Drafts that start from your analytics

The agents read your posting history first: the hooks that earned the click, the pillars your audience answers, the rhythm of what worked. The draft sounds like you because it learned from you, not from a form.

A reply ready for every person who matters

Build custom lists of the people you want to stay visible to. Their new posts arrive in one feed with a comment drafted in your voice under each. You edit or approve every one before it goes anywhere.

From draft to published, without the paste

Finished drafts go to the queue and publish through LinkedIn’s official API, with the first comment written alongside. Connection notes and follow-ups are drafted with the context already in place. Nothing goes out until you approve it.

Connect LinkedIn and you have a strategy, your pillars, and your first post ideas in about fifteen minutes.

Why them, in the first sentence

Every recipient of a cold message runs the same check before reading past line one: is this actually for me, or am I a row in a spreadsheet? The first sentence has to settle it, which is why the generator opens with why them specifically, built from whatever you put in the recipient field. "You have posted twice about hiring senior backend people" survives the check. "I came across your profile" does not, because it is what the spreadsheet says too.

This is also why the credibility field is required. The recipient's second question is "who is this person to ask", and one concrete sentence ("30 of our last 40 placements were senior backend roles in healthcare") answers it without the résumé. Credibility stated as fact reads fine; credibility stated as enthusiasm reads as a pitch deck.

One ask, stated plainly

The middle of the message is one sentence: the ask. Twenty minutes, an intro, a look at a role, an answer to a specific question. Two asks halve each other, and a vague ask ("would love to connect and explore synergies") transfers the work of figuring out what you want onto the person you are asking a favour of. Decide before you generate; the purpose field is the decision.

Then send it and stop. One follow-up a week later is persistence; more is a pattern the recipient has seen from every tool-armed seller this quarter. The scarcity of InMails is on your side here, since it makes restraint the default.

Questions

What is an InMail on LinkedIn?
A message to someone you are not connected to, available on Premium, Sales Navigator, and Recruiter accounts, which allot a limited number per month. The scarcity is the useful constraint: each InMail costs you something, so it forces the question a free message never does, which is whether you can justify this person's attention.
How long should an InMail be?
Short enough to be read to the end on a phone: this generator writes 60 to 120 words. The body field allows 2,000 characters, and using them all is the classic mistake, because a long message from a stranger reads as work. Why them, the ask in one sentence, an easy out. Anything more belongs in the call you are asking for.
What makes a good InMail subject line?
Under 60 characters, and it says what the message is about without bait. The subject line of an InMail competes with email subject lines, and the recipient applies the same filter: "Quick question" and "Opportunity" get deleted on sight, while "Your two open senior backend roles" gets opened by exactly the person it is for. LinkedIn caps the field at 200 characters; you should stay far under it.
Why does the message include an easy out?
Because pressure reads as desperation, and an explicit "if this is not relevant, ignore me" reads as confidence. It costs you nothing when the answer would have been no anyway, and it noticeably raises the quality of the yeses, because the person replying chose to. The generator writes that energy without the cliché phrasing.
Is this InMail generator free, and is my input stored?
Free, no account, with a daily cap so it stays available. The three fields are sent once to generate the subject and message, and are not stored.
How do I raise the odds before sending anything?
Be a name they have seen. An InMail from a stranger competes with every other cold message; an InMail from someone who left two sharp comments on their posts this month is a follow-up. Depost AI keeps you visible to chosen people with lists and replies drafted in your voice, which is the slow, compounding way to make cold outreach warm.
