A LinkedIn InMail can have up to 200 characters in its subject line and up to 1,900 characters in its body (InMail character limits, retrieved 24 October 2026). LinkedIn Help doesn't state a limit for ordinary messages between connections.

InMail is a LinkedIn message you send to someone you aren't connected to, using credits from a paid plan such as Premium or Sales Navigator. Bokka is an AI-first CRM for your LinkedIn inbox.

The limits at a glance

Part	Limit	Source
InMail subject line	200 characters	LinkedIn Help
InMail body	1,900 characters	LinkedIn Help
Message to a connection	Not published by LinkedIn Help	—

Some older LinkedIn pages mention 2,000 characters for the InMail body; the current help page says 1,900, so plan for 1,900.

Other InMail rules worth knowing

No read receipts for the sender. LinkedIn says read receipts and typing indicators don't appear to people who send InMail (read receipts, retrieved 24 October 2026).
You can't delete a sent InMail. You can edit one only before it's accepted or within 60 minutes of sending (edit or delete a sent message, retrieved 24 October 2026). See can you unsend a LinkedIn message.
Replies go where you sent from. Replies to InMail sent from Sales Navigator land in the Sales Navigator inbox, not your LinkedIn inbox (LinkedIn Help: Sales Navigator or LinkedIn inbox, retrieved 24 October 2026). See Sales Navigator and LinkedIn messages in one place.

How long should an InMail be?

The limit is a ceiling, not a target. Someone who doesn't know you decides from the subject and the first line whether to read on, often on a phone. A useful shape:

Subject: what it's about in a few words, not a teaser.
First line: why you're writing to them in particular.
One or two lines: what you're offering or asking.
One question that's easy to answer.

If you send similar InMails often, save the shape as a snippet. In Bokka, snippets fill in the person's first name and company for you and won't send until every gap is filled; on Pro, AI can draft a reply in your voice and make it shorter. See Snippets and Write with AI.
