How does this LinkedIn message generator work?
The generator assembles a message from what you actually know about the prospect: their first name, their role, a signal you noticed and the topic you can help with. It uses no artificial intelligence and invents nothing. If a field is empty, the matching sentence disappears instead of being replaced by filler.
You pick an approach and a way to close, then copy the text. The counter tells you whether you stay under 200 characters, the length with the best reply rate in the study. Always reread the message before sending it: it is a starting point, not a final draft.
What makes a good first message on LinkedIn?
- Talk about the person before talking about yourself. The opener uses a verifiable fact: a recent post, a new role, a hire. Never a generic compliment.
- Ask one question about their situation. A two-option question, like “in-house or with an outside partner?”, takes minimal effort to answer.
- Do not pitch your offer. The person did not ask for anything. The first message opens a conversation; the offer comes once they have described a need.
- Keep it short. On a phone, 200 characters is about three lines.
- Never invent common ground. Do not claim you met at a trade show or spoke with a colleague if it is not true.
These are the rules MimikFlow applies to every first message it writes for its users.
Which approach should you choose for your message?
| Approach | When to use it | What you need |
|---|---|---|
| Observation | The prospect posted or shared something recent | A precise, dated signal |
| Direct question | No signal, but you know their job well | Their role and your topic |
| Congratulations | New role, funding round, hiring | A real, recent event |
| Proof | You have a real, comparable customer case | A result you can prove |
A signal helps, but less than people think. In our 2026 study (in French), a job change, a funding round or a hiring announcement lifts the reply rate to 40.9%, against 37.1% without news. Message length and prospect source weigh more.
The proof approach only uses the case you write yourself. Without a real case, the generator removes the sentence instead of making one up. A made-up number in a first message takes one search to check and ends the conversation.
Should you ask for a call in the first message?
The generator offers three ways to close. A question about the prospect's situation is the one we recommend: it takes little effort and opens the conversation. Offering a resource works when you have something genuinely useful to send. Asking for a 15-minute chat is the most direct option: it asks a lot from someone who does not know you yet, so keep it for prospects who are already warm.
On the number of questions, the study is clear: among strangers, a message with no question gets 34.7% replies, one question 35.7% and two questions 34.8%. One well-chosen question is enough. Punctuation does not rescue a message that is too long.
What does a strong first message look like?
Example: observation and question
Hi Claire, I saw your post about onboarding new sales reps. As a sales director, do you handle sales team training in-house or with an outside partner?
This message stays under 200 characters. It cites a fact Claire will recognize, asks a question she can answer in a few words and says nothing about the offer. If she answers “in-house”, the conversation can move on to how her team is organized.
Counter-example
Hi Claire, I am the founder of a training firm that has supported sales teams for ten years. We have developed a unique method that improves the performance of your reps. Would you be available for a 30-minute call this week so I can present our approach?
The counter-example talks about the sender before the person, pitches the offer, asks a stranger for 30 minutes and runs past 250 characters. In the study, first messages of 200 to 299 characters get 39.1% replies, and 300 to 399 characters 35.8%, against 50.5% under 200.
What should you do if the prospect does not reply?
Follow up. In our 2026 study, the first message only brings in 53.6% of replies. The first follow-up adds 21.9 points, the second 9.2 points, and three follow-ups cover 90.2% of all observed replies. Many prospects simply missed your message or meant to answer later.
A good follow-up is not a copy of the first message with “just circling back”. It stays short, starts again from the prospect's situation and asks a new question. Space follow-ups a few days apart and stop as soon as the person says no: an explicit refusal ends the sequence.
How do you personalize a message without spending an hour on it?
Look for one fact per prospect, not a full file. Their latest post, their job title or a hiring announcement from their company is enough. Check the date: a year-old post presented as recent has the opposite effect. Also check that the post is really theirs and not a share, and quote it in your own words rather than copying it.
If you add a note to your invitation, use the LinkedIn connection note examples and check its length: LinkedIn caps it at 200 characters.
Past a few dozen messages a week, this work becomes hard to keep up by hand. MimikFlow reads each prospect's profile and recent posts, writes a short first message following these rules and sends it once the invitation is accepted.
Frequently asked questions
How long should a LinkedIn first message be?
Under 200 characters, about three lines on a phone. In our 2026 study, those messages got a 50.5% reply rate. With cold prospects, they led to a meeting in 8.0% of cases, against 1.9% above 500 characters.
Should the first message be formal or casual?
Match the person. A relaxed tone works with freelancers, independents and early-stage founders. A more formal tone is safer with executives at large companies and in traditional industries.
Does the generator use artificial intelligence?
No. It assembles your message from fixed templates and what you type. Nothing is sent to a server.
Can I mention my offer in the first message?
Better to wait. The prospect did not ask for anything, and a pitch turns the message into an ad. Ask about their situation first; the offer comes once they have described a need.
What time should I send the first message?
Time matters little: in the study, reply rates stay between 35.1% and 40.9% from 8 am to 5 pm. What matters is not letting a warm prospect cool down, for example someone who just reacted to your post.
