Start with the number
Most people optimise the message and never measure the acceptance rate. That’s backwards, because acceptance rate tells you which problem you actually have.
- Under 25 percent: your targeting is wrong. Stop editing the note.
- 25 to 35 percent: targeting is roughly right, the note is generic.
- 35 to 50 percent: working. Move your attention to what happens after the accept.
- Over 60 percent: you’re mostly messaging warm contacts. Fine, but it won’t scale.
Acceptance rate also matters for account health. A pile of ignored invitations is one of the signals LinkedIn uses to decide an account is spamming, so this number protects you as well as your pipeline. More on that in the limits guide.
The structure that works
Four parts, in this order, in under 300 characters.
1. Their name. Once, at the start. Not three times.
2. One specific reference. This is the whole message really. Something that could only apply to them: a post they wrote, a role they just started, a job they’re hiring for, a company they both worked at, a mutual connection by name. If you can’t find one, they shouldn’t be on your list.
3. Why you, in half a sentence. Not what you sell. Why you’re a plausible person for them to know. “I ran SDR teams for a decade” is a reason. “I help companies scale revenue” is not.
4. Nothing. No ask, no link, no calendar, no “would love to hop on a call”. The ask comes after they accept.
A worked example
Weak:
Hi Sarah, I’d love to connect and share how we help B2B companies like yours book more meetings. Let me know if you’re open to a quick chat!
Strong:
Hi Sarah, your post about killing your team’s cold call quota was the most sensible thing I read this week. I ran SDR teams at Salesforce and made the opposite mistake for years. Would be good to be connected.
Same length. The second one could only have been written to Sarah.
Twelve openers to avoid
“I’d love to connect.” “I came across your profile.” “I help companies like yours.” “Quick question.” “Hope this finds you well.” “I noticed you’re the {title} at {company}.” “We’ve never met, but.” “I’ll keep this brief” followed by four paragraphs. “Are you the right person to speak to about.” “Congratulations on your new role!” with no other content. Anything with an emoji. Anything with your calendar link.
Most of these fail for the same reason: they’d read identically to a thousand other people.
Where to find the specific reference
In rough order of how well they perform: a recent post or comment they wrote, a role change in the last 90 days, a job ad from their company, a shared employer or school, a named mutual connection, a company announcement, a shared group. Their headline is the weakest option and the one most people use.
Doing this at scale
The tension is obvious: specificity is what works, and specificity doesn’t scale by hand. Forty really researched requests a day is a full-time job.
This is the gap Prospectio’s ICP filter closes. It reads each profile, checks the person fits your ICP at all, picks the strongest available reference, and writes the note in the structure above. Poor-fit prospects get skipped rather than sent a worse message. Then a voice note after they accept, which is where the reply rate comes from.
After the accept
Don’t pitch in the first message. The accept is permission to start a conversation, not permission to sell. Wait a day, send something short and human, and make the first ask small.
