What a LinkedIn InMail Is and When to Send One

An InMail is a paid LinkedIn message that reaches a member you are not connected to. It uses one credit from a paid subscription, and a recipient who turned InMail off cannot be reached at all.

An InMail is a paid LinkedIn message that reaches a member you are not connected to. LinkedIn calls InMail "a premium feature" that lets you "directly message another LinkedIn member that you're not connected to," while a free Basic account can only message people it is already connected to, according to LinkedIn Help (opens in a new tab). That single rule explains most of what surprises people about InMail: why a stranger can message them, why it costs a credit, and why some people never receive one.

What an InMail actually is

Two LinkedIn features are easy to confuse. A message is the normal inbox conversation you have with a 1st-degree connection: LinkedIn states you can message your connections or LinkedIn Pages for free (LinkedIn Help (opens in a new tab)). An InMail is a separate, metered way to open a conversation with someone outside your network.

InMail is sold inside several LinkedIn subscriptions rather than on its own. LinkedIn's messaging help lists InMail as offered through paid subscriptions that include Premium, LinkedIn Recruiter and LinkedIn Sales Navigator (LinkedIn Help (opens in a new tab)). The same page also names LinkedIn Campaign Manager in that group, but it describes Campaign Manager as an ad management tool for Sponsored Messaging campaigns, not as a member InMail credit seat, so this article keeps it out of the per-seat credit maths. The credits you spend are tied to the subscription they came from.

One consequence matters before you draft anything: a recipient can refuse InMail entirely. LinkedIn states plainly that "you can't message a member if they've chosen not to receive InMail messages in their message preferences settings" (LinkedIn Help (opens in a new tab)). No credit is spent on someone who has closed that door; the option simply is not offered.

How an InMail reaches someone outside your network

An InMail is not an email and does not require the recipient to know you. When you send one, LinkedIn charges your balance by one credit.

InMail is deliberately short. LinkedIn documents a subject line of up to 200 characters and a body of up to 2000 characters (LinkedIn Help (opens in a new tab)). Treat those as the whole canvas: there is no room for a proposal, and long openers compete badly with the one-line subject that LinkedIn asks you to make "direct, informative" (LinkedIn Help (opens in a new tab)).

Premium credits and Sales Navigator credits are not interchangeable. LinkedIn states that "Premium InMail message credits can't be used to send InMail messages on Sales Navigator or LinkedIn Recruiter" (LinkedIn Help (opens in a new tab)). If your team buys both, the two balances stay separate.

What an InMail costs to send

Each InMail uses one credit, and LinkedIn confirms there is no unlimited tier: "We currently don't offer a subscription plan with unlimited InMail message credits" (LinkedIn Help (opens in a new tab)). A credit can come back, though. In Sales Navigator, LinkedIn grants an InMail credit "for every InMail message that receives a response within 90 days of the date sent," and messages without a response do not return the credit (Sales Navigator Help (opens in a new tab)).

That detail changes how a balance behaves, not the money you owe. A qualifying reply restores the credit, so a replied InMail costs no net credit, while silence does not return it; the subscription fee is payable either way. The full allowance picture, plan by plan, is in how LinkedIn InMail credits work.

When an InMail is the right tool

InMail is built for the first touch on someone outside your network, especially when a connection request is a poor fit. It suits situations like these:

  • You need to reach a specific decision-maker and you have no shared group, coworker or Open Profile route to them.
  • You have something concrete to say that a stranger can judge in a few seconds, such as a specific trigger at their company.
  • You want the recipient to be able to reply without accepting a connection first.

When an InMail is wasted

Reach for something cheaper first when it fits. If the person is a 1st-degree connection, a normal message is free. If they are a Premium member who enabled Open Profile, LinkedIn states you "can message them for free" without spending an InMail (LinkedIn Help (opens in a new tab)). And if a short note attached to a connection request would do the job, that keeps the InMail for a harder target — see InMail versus message for that call.

An InMail is also wasted when the pitch is generic. LinkedIn's own writing guidance, written for Recruiter, says to personalize the message to the person, explain what you want from the conversation, and avoid pasting a job description or a bare link (LinkedIn Help (opens in a new tab)). A message that reads like a template spends a credit and earns nothing.

What the recipient sees

InMail exists so you can privately contact a member outside your network: the sources reviewed here document the sending form and the recipient's option to turn InMail off, but not the exact screen the recipient opens, so treat the recipient-side layout as something LinkedIn controls rather than a fact to rely on. LinkedIn does warn that messages marked as spam can lead to restrictions on a Sales Navigator account (Sales Navigator Help (opens in a new tab)), which is one more reason to keep the first line specific to the person.

If you want to see message wording modelled on a real trigger instead of a template, the InMail examples and templates piece works through a few. If you are comparing outreach tools, Visit Clapa.

The limit to keep in mind

InMail is metered and not unlimited, and it sits inside LinkedIn's broader messaging limits. LinkedIn says it "limits how many messages a member can send in a certain time period" and does not publish the number (LinkedIn Help (opens in a new tab)). Plan a fixed, modest number of InMails per sender per week rather than assuming you can spend every credit on one day.

FAQ

Is an InMail the same as a direct message?

No. A direct message goes to a 1st-degree connection for free; an InMail is a paid feature that reaches a member outside your network (LinkedIn Help (opens in a new tab)).

What does it mean when a LinkedIn message is labelled InMail?

It means the sender reached you outside your network using an InMail credit from a paid LinkedIn subscription, rather than a free message between connections.

Can I send InMail without a paid subscription?

No. LinkedIn states you must upgrade to a Premium-class account to use InMail (LinkedIn Help (opens in a new tab)).

Does sending an InMail always cost a credit?

It uses one credit when it sends. A response within 90 days returns the credit in Sales Navigator; silence does not (Sales Navigator Help (opens in a new tab)).

LinkedIn InMail vs Message: Which Should You Send

Send a free message to a 1st-degree connection and save InMail for people outside your network who have no free route. An InMail costs one credit and needs the recipient to accept InMail, while a connection note is free but limited to three personalized notes a month on a standard account.
