Quick answer
A LinkedIn message framework is the order you put the reason, the question and the ask in, and the right one depends on where the message sits in your sequence. Seven cover most B2B outreach. For connection notes: the signal note and the shared-link note. For the first message after someone accepts: the one-question opener and the content reply. For a follow-up: give-first. For InMail or a senior stranger: HEART. When it's time to ask: problem, offer, ask. Whichever you use, keep notes under 200 characters, ask one question per message and save the pitch until they reply.
What every LinkedIn message has to do
I write LinkedIn messages next to cold email for B2B outbound, and every example below was written for this article, for a made-up prospect. Before the frameworks, three rules all seven follow:
- One reason that only this person would recognise. A message for everyone speaks to no one.
- One question. Two asks make the reader choose, and most people choose neither.
- No pitch before they reply. The note gets them to accept, the first message gets a conversation going and what you sell comes after.
The data backs that split. In Belkins' data on 11.5 million connection requests sent in 2025, a note lifted replies from 5.3% to 8.2% at a small cost to acceptance (27.6% without a note, 25.3% with one). And in Expandi's data on 13.2 million requests, replies to the note itself fell from 3.5% to 2.2% between May 2025 and April 2026. The note opens the door. The message after it starts the conversation.
I haven't found a published test that ranks LinkedIn message frameworks against each other, so pick by situation, not by a leaderboard.
The 7 frameworks at a glance
| Framework | The order | Where it goes | Use it when |
|---|---|---|---|
| 1. Signal note | What they did, who you are, connect | Connection note | They just did something |
| 2. Shared-link note | The real link, why you're writing, connect | Connection note | You share an event, a community or a mutual contact |
| 3. One-question opener | Thanks, one question about them | First message | They accepted a blank request |
| 4. Content reply | Their post, your point, a question | First message | They post about the problem you solve |
| 5. Give-first | Something useful, why it's for them, want it? | Follow-up | No reply to the first message |
| 6. HEART | Hook, empathy, authority, request, thanks | InMail or a first message to a senior stranger | You get one shot and need to say who you are |
| 7. Problem, offer, ask | One problem, one offer, one interest question | The ask | They replied, or it's your third message |
Connection notes: the signal note and the shared-link note
A note is capped at 200 characters, about 30 to 35 words, and free accounts get 3 a month by LinkedIn's newer help page (an older one says 5). So a note carries one reason to connect and nothing else. Most of your list should get a blank request. These two are for the few who need a reason, and I cover who they are in how many connection notes a free LinkedIn account gets.
1. The signal note
The order: what they just did, who you are in one line, an invitation to connect.
"Hi Daniel, saw Northwind just opened an Amsterdam office. I work on payroll setup for companies hiring in a new EU country. Would be good to connect."
Use it when something happened in the last few weeks: a new role, a new office, a funding round, a hiring push or a post about your topic. The best lead is the one who just did something. Watch for stale triggers. A funding round from three months ago isn't news, and congratulating every job change reads like a bot.
2. The shared-link note
The order: the link you really share, why you're writing, connect.
"Hi Ieva, we were both at the Riga SaaS meetup on Thursday. Your question about usage-based pricing was the one I wanted to ask. Glad to connect."
Use it when you share something real: the same event, the same community or a mutual contact who told you to reach out. Watch for borrowed names. Ask the mutual contact before you name them, and if they barely know either of you, it isn't a link.
First messages: the one-question opener and the content reply
The first message after someone accepts starts most conversations, so this is where your effort goes. Send it within a day of acceptance. For when each message goes out, see how to build a LinkedIn outbound sequence.
3. The one-question opener
The order: thanks, one question about their situation, a short line on why you ask.
"Thanks for connecting, Marius. Quick question: now that you're selling into Germany, are your reps writing to prospects in German or in English? I see teams split on this."
Use it when they accepted a blank request, which will be most of your list. The question has to be about them, answerable in one line and something you'd want to know anyway. Watch for fake questions. "Are you struggling with pipeline?" is a pitch with a question mark at the end.
4. The content reply
The order: their post, one point of your own, a question.
"Hi Sofia, your post on cutting the demo form to three fields made me look at ours. One thing I'd watch: fewer fields can mean more bookings from people who aren't a fit. Did you see that after the change?"
Use it when they post about the problem you solve. The post tells you what they care about this month, in their own words. Watch for praise with nothing behind it. "Great post!" starts nothing, and if you haven't read the post, don't mention it.
Follow-ups: give-first
5. Give-first
The order: something useful you made or found for them, one line on why it's for them, "want it?".
"Marius, one more thing: I pulled the 20 German mid-market logistics firms that posted sales roles this month. Might be useful for your reps. Want the list?"
Use it when the first message got no reply and you need a new angle instead of "just following up". The test: would it be useful even if they never buy from you? Watch for gifts that are really about you. A case study of your own product is still a pitch.
InMail and senior strangers: HEART
6. HEART
HEART comes from PhantomBuster: a hook that shows you've done your homework, empathy for their world, one line of authority on why you're worth their time, a small and specific request and thanks. It's the longest framework here, which is why it fits InMail. LinkedIn's help page says you can't send a second InMail to someone until they respond to the first, so that one message has to say who you are and why you're writing.
Subject: "Your first quarter as CRO"
"Hi Kristina, congrats on the CRO role at [Company]. New sales leaders usually spend the first quarter working out which pipeline numbers to trust. We audit pipeline reporting for SaaS teams of 50 to 200 people. Would a short review of your pipeline reports help before your first board meeting? Either way, good luck with the new role."
Use it when the person is senior, unlikely to accept a stranger and worth one of your credits, or when a first message has to introduce you before they'll answer. Watch for the authority line growing into a pitch. One line, then the request. I cover when an InMail is worth a credit in InMail vs connection request vs cold email.
The ask: problem, offer, ask
7. Problem, offer, ask
The order: one problem in their words, what you do about it in one line, one question about interest.
"Marius, straight question: reps writing to German buyers in English often get polite silence. We write and test German sequences with your team in the first month. Is that worth a conversation?"
Use it when they replied to an earlier message, or as your third message when they haven't. After a yes, suggest one specific time, like "Does Tuesday at 10:00 work?", rather than sending a calendar link. Watch for a calendar link in the first ask. It asks a stranger to commit time before they care.
How to pick a framework
Go through these in order and stop at the first yes:
- Did they just do something? Signal note.
- Do you share a real link? Shared-link note.
- Neither? Blank request, then the one-question opener, or a content reply if they post about your topic.
- No reply to the first message? Give-first.
- Senior, won't accept a stranger and worth a credit? HEART, as an InMail.
- They replied, or it's your third message? Problem, offer, ask.
All seven break the same way: a detail that isn't true, isn't recent or isn't about this person. A mutual contact who barely knows you, a trigger from last quarter, a post you didn't read. The structure is the easy part. If you write email too, the same idea runs through my cold email copywriting frameworks.
Check before you send. Could this message go to anyone else on your list with only the name changed? If yes, it reads like a template, because it is one. Find the one detail that makes it theirs, or send a blank request and save your words for the first message.
Key takeaways
- A LinkedIn message framework is the order of the reason, the question and the ask. No published test ranks them, so pick by situation and by where the message sits.
- Connection notes: the signal note or the shared-link note, under 200 characters, one reason to connect. Most people get a blank request.
- First messages: one question about them, or a reply to their post. No pitch.
- Follow-ups give something useful. HEART fits InMail. Problem, offer, ask is for when it's time to ask, with one interest question and no calendar link.
- Every framework fails the same way: a detail that isn't true, isn't recent or isn't about this person.
FAQ
What is the best LinkedIn message framework?
None wins everywhere, and I haven't found a published test that ranks them. Use the one-question opener for most first messages, the signal note when someone just did something and HEART for InMail.
What should my first LinkedIn message say after someone accepts?
Thank them and ask one question about their situation, with no pitch. Send it within a day, while they still remember clicking accept.
How long should a LinkedIn outreach message be?
A connection note is capped at 200 characters, about 30 to 35 words. Keep the first message to two or three sentences with one question, because most people read it on a phone.
What is the HEART framework for LinkedIn?
A five-part structure from PhantomBuster: hook, empathy, authority, request and thanks. It's longer than the others, so use it for InMail or a first message to a senior person who doesn't know you.
Should I use AI to write LinkedIn messages?
It barely moves the numbers either way. In Expandi's 2025 data analysed by Belkins, campaigns using an AI prompt got 7.3% replies against 7.0% without. Use it for the structure if you like, but check that every detail is true for that person.
