In short: Keep it short, specific, and about the role — not about you needing a job. A connection note gives you 200 characters on a free LinkedIn account (300 with Premium), so it can hold exactly one sentence of relevance and one offer. The first real message should stay under about 400 characters, because short, personalized messages get answered noticeably more often than long ones. Follow up once.
Recruiters at busy companies work through hundreds of messages a day. Everything below is written for that reality: they are not being rude, they are triaging.
The three situations (they need different messages)
- You applied and want it noticed. Reference the requisition, give one proof point, offer something concrete.
- A recruiter contacted you. Answer fast, state your situation plainly, and ask the two questions that decide whether it is worth a call.
- Nobody has contacted you and there is no posting. This is networking, not applying. Ask for information, not a job.
The connection note: 200 characters, one idea
A connection request on a free account allows a note of 200 characters; LinkedIn Premium and Sales Navigator allow 300. Free accounts are also limited to a small number of personalized notes per month, so spend them where they matter. The practical sweet spot is 120–180 characters — the whole note visible without a click.
Structure: who you are for this role → the one thing that matches → a light offer.
Hi Maya — I’m applying for the Senior PM role on your team. Three years owning a 400-SKU demand forecast, which looks like the core of the job. Happy to send specifics.
That is 168 characters. What it deliberately leaves out: your life story, “I’d love to pick your brain”, and the phrase “I know you’re busy”.
The first message: under 400 characters
Once you are connected — or if you can message directly — the first real message still stays tight. Messages under roughly 400 characters get meaningfully more replies than longer ones, and personalized ones outperform templated ones by a wide margin. Most replies that do come arrive within a day, so send and then leave it alone.
Hi Maya, thanks for connecting. I applied for the Senior PM opening yesterday (req 4182). Closest proof point: I rebuilt a 400-SKU demand forecast and cut stockouts from 9% to 3% in two quarters. If it’s useful I can send a one-page take on the first 90 days. Either way, good luck with the search.
298 characters. Four moves: context, the requisition, one number, one offer. No attachment on the first message — offer it, send it when they say yes.
When a recruiter contacts you first
This is the easiest message to get right and the most commonly fumbled. Reply even if the answer is no; recruiters keep notes, and a clean “not now, here’s what would change that” is worth more than silence.
Thanks for reaching out, Maya — yes, interested. Short version: 6 years in PM, the last 3 on supply-chain forecasting, currently at a 400-SKU retailer. Two questions before we talk: is the range still 150-170k, and is the team remote-first? Happy to take a call Thu or Fri.
273 characters, and it does four useful things: confirms interest, positions you in one line, asks about compensation early (in many U.S. states the range must be published anyway), and offers concrete times.
If you are not interested: say so in two lines, say what would interest you, and offer a referral if you have one. That is how you stay in the file for the next role.
Cold outreach with no posting
Different goal: you want information, not a decision. Ask something that costs them under a minute to answer.
- Good: “Is the platform team still hiring into the forecasting side this quarter, or is that on hold?”
- Bad: “Can I send you my resume?” — that asks them to do the work of finding you a fit.
Expect a low reply rate. Cold outreach is a numbers game with a small denominator, which is why it should never be your main channel.
Following up: once
One follow-up, five to seven business days later, in the same thread. Add something rather than repeating yourself: a link to relevant work, a short note on why the role still fits.
Hi Maya — following up once on the Senior PM role. Still very interested, and happy to answer anything. If the search has moved on, no problem at all — knowing either way helps.
177 characters. After that, stop. If they reply months later, that is normal; pipelines reopen.
Mistakes that get you muted
- The wall of text. If it needs scrolling on a phone, it will not be read now — and “now” is the only slot you get.
- No role, no requisition. “Any openings?” makes them do the search.
- The guilt opener. “I’ve applied 40 times and heard nothing” is true and understandable, and it still reads as pressure.
- Volume. Invitation limits exist, and blasting identical notes gets your account flagged long before it gets you a job.
- Attachments on first contact. Offer, then send.
Where JACVault fits in this
Honestly: not in your LinkedIn messages. Writing and sending outreach is not something we ship today — an outreach suite is on our roadmap, and it is not on this site as a feature until it exists.
What we do is the part your message points at: the tailored resume and cover letter for that specific posting, plus a tracker that keeps the requisition, your notes and the next step on one card — so the follow-up above takes ten seconds to write correctly.
