LinkedIn InMail credits: how many you get, when they renew, and what they cost

InMail is a rationed channel, and the rationing rules are scattered across three LinkedIn help pages. Here is the whole mechanics picture in one place - monthly allotments per plan, renewal timing, accumulation caps, the credit-back rule, and the surprises that catch paying users. All facts from LinkedIn’s own help pages, checked November 1, 2026.

The monthly allotment, per plan

• Premium Career: 5 credits a month, accumulating to a maximum of 15.
• Premium Business: 15 a month, maximum 45.
• Premium All-in-One: 30 a month, maximum 90.
• Sales Navigator (Core, Advanced and Advanced Plus alike): 50 a month, maximum 150.
• Recruiter Lite: 30 a month, maximum 120. LinkedIn Hiring Pro: 5 per job posting, from a separate pool that does not touch your regular credits.

The FAQ also sets the format: an optional 200-character subject line and a 2,000-character body.

No plan offers unlimited InMail, and on Sales Navigator you cannot buy extra credits - the help page says so outright. When the credits run out, the month is over for cold InMail.

When credits renew

For Premium plans, the new allotment lands on the first day of your billing cycle - the anniversary of your sign-up date, which you can see on your My Premium page. Sales Navigator is different: credits renew on the first day of every calendar month, in UTC, whatever your billing date is. If they have not renewed by the second day, LinkedIn says to contact support.

Two renewal rules matter more than the date. Credits expire after 90 days, so hoarding has a ceiling set by the accumulation caps above. And every InMail that gets an answer within 90 days - an accept, a decline, even a one-tap Quick Reply - is credited back. A pending message is neither, so a credit spent on someone who never responds is simply gone. The mechanics reward messages worth answering; what real senders report on response rates shows how steep that bar is.

The rules that surprise paying users

Five is really five. A recurring InMail theme on Reddit is disbelief: in an April 2025 thread, a job seeker who bought Premium expecting open messaging discovered a 5-credit month, and a recruiter commenting later called discovering the same limit on their own account a ripoff. Premium is a bundle in which InMail is a small line item - we broke down what the plan actually buys for outreach - and the credit counter in the compose window is the only warning you get.

One conversation per person until they answer - on Premium. On Premium, you cannot send a second InMail to the same member until they respond to the first. Sales Navigator explicitly permits a second InMail to the same person before a reply, at the cost of another credit. On both, LinkedIn sends the recipient an automatic reminder within three days. On Premium, there is no follow-up ladder inside InMail.

Your balance can outlive your ability to send. One Sales Navigator trial user reported a 65-credit balance and a hard stop after 35 sends in a month. LinkedIn’s public pages describe no separate monthly send cap, so treat that report as unexplained rather than as a hidden rule - but if it happens to you on a trial, the balance number is not the binding constraint, and support is the route.

Leaving costs you the balance. Cancel a Premium subscription and the InMail balance zeroes immediately. Credits are not transferable between products either: Premium credits do not work in Sales Navigator or Recruiter, and moving between plans does not carry them over.

Free routes bypass the meter entirely. Messages to first-degree connections, fellow group members and Open Profile members cost no credits at all. The full map is in how to message someone on LinkedIn without Premium - for most founders, those routes carry the volume and the 50-credit plans are for the exceptions.

What we would do

Spend credits only where the free routes cannot reach, and write every InMail as if it has to earn its credit back - because mechanically, it does. If you find yourself rationing 5 or 15 credits a month, the answer is rarely a bigger plan; it is a better target list and a note worth accepting. Dollar Outreach is built for that side of the line: you paste profile URLs, it queues the invitation note and follow-ups under fixed daily caps, and you read and send every message yourself. No credits involved, because the routes it uses are free.

Limits

• The 35-send trial ceiling is a single self-reported account with no published rule behind it.
• User reactions are from public Reddit threads, self-reported.
