LinkedIn connection request messages: limits, when to skip the note, and 30 examples

Most advice about connection notes assumes a note always helps. Ours didn't. We sell B2B software development services, mostly to founders and C level people, and LinkedIn invites are where a lot of those relationships start. So we've sent a lot of them, with notes and without, and we counted.

This guide covers the hard limits first, then what our numbers say about writing a note at all, then the notes people have learned to ignore. The 30 examples at the end weren't written by hand. They came straight out of the connection note writer in Fezerli, unedited, so you can see what a template free note looks like when it's built from one line of someone's headline.

How long can a LinkedIn connection request message be?

Here's what LinkedIn documents and what it leaves vague. Where help pages contradict each other, the table says so instead of picking one.

What happens when a free account runs out of notes? You can still send the invite, just without a message, and LinkedIn offers Premium in the box where the note would go. The allowance resets each month. Notice what that means in practice: on a free account, sending personalized invites in bulk simply isn't possible. Mass notes are a Premium thing.

Two more limits matter more than the character count. Invites that people ignore or mark as “I don't know this person” count against you, and a big pile of pending invites looks like spam. If you withdraw an invite, LinkedIn won't let you invite the same person again for up to three weeks. We've covered how those patterns lead to restrictions in why LinkedIn accounts get restricted.

Should you add a note to a LinkedIn invite? What 29,504 invites told us

We looked at every invite our team and clients sent from about 50 LinkedIn accounts over the last year: 29,504 in total, almost all to decision makers at B2B companies. On average, invites without a note were accepted about 2.3% more often than invites with one.

Why would a blank invite do better? We think it's because a note changes how the invite is read. A blank invite gets judged on your photo, your headline and who you know in common. A note gets judged as a message, and most notes read like the first step of a pitch. People who get a dozen of those a week have learned to decline anything that smells like one.

But the average hides the interesting part. In campaigns where the note offered something concrete, most of all meeting in person (“I'm in Milan on the 12th and 13th, coffee near your office?”), acceptance reached 48% in some of them. That's 2.5 to 3.4 times what we normally see with the same kind of buyer. Same accounts, same audience. The only thing that changed was a real reason to say yes.

Is that true for every audience? Probably not. Recruiters, students and people building a network in a new city may see the opposite. Our numbers come from selling services to busy executives, and that's the audience they describe. Test it on your own: send 100 invites with a note and 100 without to the same kind of person, and compare after three weeks.

Which connection request messages scream bot or sales?

These notes have been sent so many times that people recognize them from the first five words. Each one tells the reader either “this came from a tool” or “a pitch is coming next”. Usually both.

We learned this one the hard way. The first version of our own note writer leaned on exactly these patterns. Given 24 different people, it wrote almost the same sentence 20 times:

Both introduce the sender, whose name and headline already sit right next to the note. Both restate the other person's headline as if it were an insight. And “stood out” plus “I'd value connecting” are on everyone's list of AI tells. The rewrite banned all of it: no introducing yourself, no restated headline, no invented reason, no “fellow”, “keen to connect”, “came across your profile”, “caught my eye”, “impressive”, “journey” or “synergies”. It also gives every note a different shape and a different closing line, so 24 notes don't sound like one.

30 LinkedIn connection request message examples

Every note below came out of Fezerli's note writer unedited. The sender is a partnerships person at a software development company, the recipients are made up people with realistic headlines, and the writer saw only the name, the headline and, for the last group, one line of extra context. Steal the shape, not the words. If the same note goes to 50 people, it becomes the template everyone learned to ignore.

The plain note (4 examples)

Greeting plus a short ask. It's polite and harmless, and if this is all you'd write, our data says you can leave the note empty and lose nothing.

Light curiosity about their field (6 examples)

One line that shows you know what they work on, without restating their job title. It's about the field, not about them, so it can't come across as flattery.

“Would be interesting to hear” (6 examples)

Names one specific thing from their world you'd like to hear about. The more specific the detail, like a number from their headline, the less it reads as a template.

One easy question (5 examples)

A question they could answer in a sentence if they wanted to. It's also a ready made first message after they accept.

Keeping up with what they build (2 examples)

Works for founders and product people who post about what they ship. Use it only if you'd actually read those posts.

Shared ground (1 example)

Only when your headlines really do overlap. If they don't, the writer falls back to the plain note instead of inventing a link.

Notes with a concrete reason (6 examples)

This is the group that moved our numbers. Each one got a single line of real context, like the trip, the event or the mutual contact, and the writer built the note around it. These are the only notes we'd send to a busy executive.

Did you notice what none of them do? None says who the sender is, what the company sells, or asks for a call. The 48% campaigns didn't pitch in the note either. They offered the meeting and let the profile do the rest.

How to write a connection note that gets accepted

1. Decide if it needs a note at all. No concrete reason? Send it blank. On average that did better for us.
2. Start with their first name and nothing else. No “Hope you're doing well”.
3. Say one true, specific thing. An event, a mutual person, a post they wrote, a place you'll both be. Not a compliment.
4. Don't introduce yourself. Your name, photo and headline are right next to the note.
5. Don't pitch. Nothing about what you sell, no discounts, no “quick call”. That comes later, if at all.
6. Keep it under 200 characters, even on Premium. A note that fits a free account reads like a person typed it.
7. Never send the same note twice in a row. Identical invites to strangers are a classic spam signal, and people compare notes more than you'd think.

What about after they accept? Don't send the pitch in the next minute. Reply to whatever you mentioned in the note, or wait until they post something and comment on it first. The invite opened a door, and a sales message straight after it is the fastest way to have it closed again.
