15 LinkedIn InMails worth spending a credit on.

InMail costs credits, so every one should earn a reply. These are short, specific and built around one reason to write now, with subject lines that look like a person wrote them.

The short answer

A LinkedIn InMail that gets a reply is short (three to five sentences), opens with the specific reason you're writing to this person now, names one problem they likely have, offers one piece of proof, and ends with an easy question. The subject line should name the topic plainly. Save InMail for people a connection request won't reach.

  • Use it when a request won't do. Senior people, time-sensitive reasons, or someone who ignored a well-chosen request.
  • Lead with why them, why now. A trigger, a post, a shared contact. Put it in the first sentence.
  • Three to five sentences. InMail is read on phones too.
  • One easy question. "Worth a look?" or "Is this on your list this quarter?"
  • Check for Open Profile first. Some members can be messaged without spending a credit.

InMail or a connection request?

For most outreach, a free connection request with a short note is the better first move. Our guide to InMail vs connection requests explains when each wins, and the 30 connection request templates cover the free option.

Questions

How do I write a good LinkedIn InMail?

Keep it to three to five sentences: why you're writing to them now, the problem they likely have, one piece of proof, and one easy question. Use a plain subject line that names the topic.

Is InMail better than a connection request?

Not usually. A connection request is free and opens an ongoing relationship. InMail is worth a credit for senior or hard-to-reach people and time-sensitive reasons.

Do I get InMail credits back?

LinkedIn returns the credit when your InMail gets a reply within its stated window, so well-targeted InMails cost less than they seem.

Can I message someone on LinkedIn without InMail?

Yes, if they're a connection, or if they've turned on Open Profile, which lets anyone message them without a credit.

Can Siela send InMails for me?

No. Siela's AI SDR reaches people with connection requests and messages from your own LinkedIn account, which needs no Premium or InMail credits. Use these templates when you send InMail yourself.
