What Is LinkedIn InMail? (And When It's Worth Using)

What is LinkedIn InMail?

LinkedIn InMail is a paid direct message that reaches anyone on LinkedIn, even if you're not connected to them and don't share a mutual connection. It's the workaround for LinkedIn's normal rule that free messaging is limited to 1st-degree connections. InMail comes with a paid plan (Premium, Sales Navigator, or Recruiter), each allotting a set number of credits per billing cycle, and it isn't unlimited on any plan.

How InMail credits work

You get a set number of InMail credits at the start of each billing cycle, based on which paid plan you're on. Credits accumulate if unused, up to a plan-specific cap, and they don't expire on their own. The part most people don't expect: you get a credit back automatically if the recipient responds within 90 days of you sending it. A well-targeted InMail that gets a reply effectively costs you nothing.

Premium InMail credits, Sales Navigator InMail credits, and Recruiter InMail credits are separate pools; a credit from one plan can't be used to send a message through another.

InMail vs a connection request: what's the difference?

When InMail is worth using

InMail earns its cost when a connection request would be too slow or too easy to ignore: reaching a hiring manager before a role closes, following up with a prospect who hasn't accepted your connection request, or contacting someone whose 2nd or 3rd-degree distance makes a request unlikely to get noticed. It's a weaker choice when you have time on your side, since a well-written connection request costs nothing and often converts just as well for anyone not in a hurry.

Where InMail shows up in practice

• A recruiter reaching a candidate who isn't a connection, before a role fills
• A sales rep following up on a stalled connection request with a direct pitch
• A founder reaching a specific investor or advisor outside their existing network
• Any outreach where a fast response matters more than building the relationship first

What this means for you

Treat InMail credits as a scarce resource, not a first move. Try a connection request or a warm introduction first when you have time; save InMail for the specific people worth the credit, and write it to actually earn a reply, since a reply within 90 days gets your credit refunded and a non-reply doesn't. If your outreach strategy leans more on content than cold messaging, what makes LinkedIn posts go viral covers the alternative path: getting the right people to come to you instead of messaging them first.

FAQ

How many InMail credits do I get per month?

The number depends on your specific paid plan (Premium, Sales Navigator, or Recruiter) and tier within that plan. Check your account's My Premium or Sales Navigator settings page for your current allotment, since it varies by plan and can change.

Do InMail credits roll over if I don't use them?

Yes, unused InMail credits accumulate month to month up to a plan-specific limit, and they don't expire on their own the way some other subscription perks do.

Do I get my InMail credit back if someone doesn't respond?

No, only if they do respond, within 90 days of you sending the message. A message that goes unanswered past that window keeps the credit spent.

Can I send InMail for free without a paid plan?

Generally no. InMail is a paid-plan feature. The free alternative is a connection request or a message to an existing 1st-degree connection, which doesn't require a credit.

Is InMail better than a regular connection request?

Neither is universally better; it depends on urgency. InMail delivers immediately and reaches anyone regardless of connection degree, which matters when speed counts. A connection request is free and often converts just as well when you're not in a hurry.
