LinkedIn InMail Credits: How They Roll Over and Expire

A Sales Navigator seat comes with 50 InMail credits a month, and the first instinct of everyone who buys one is to work out how to get more. The honest answer is that on Premium and Sales Navigator you cannot buy any, at any price, and LinkedIn states so directly. There is no top-up, no add-on pack, no upgrade path that raises the number. The credits reset on a schedule instead: on the first day of every month in UTC for Sales Navigator, and on your billing date for Premium.

LinkedIn Premium InMail credits breaks down what each Premium tier includes and why those credits stay separate from a Sales Navigator seat.

What you can do is stop losing the ones you have. InMail itself is a paid, ungated message to someone you are not connected to, and the credit is what you spend to send it. LinkedIn refunds a credit whenever a recipient responds, which means a well-targeted programme spends far fewer credits than it sends messages, and a badly targeted one burns the whole allowance every month. The credit system rewards precision rather than paying for it.

When Do InMail Credits Reset?

Sales Navigator InMail credits reset on the first day of every month in UTC, whatever your billing date, and LinkedIn's help page says to contact support if they have not been renewed by the second day of the month. Premium InMail credits reset on the first day of your billing cycle, based on the date of your initial sign-up, which your My Premium page shows.

So a team running both products is working two clocks. The Sales Navigator grant date is separate from the date the licence was bought, while the Premium renewal date moves with whoever signed up when.

What you get, and what you can bank

Two numbers govern the balance: the monthly allocation and the accumulation ceiling.

One InMail credit is the unit you spend to send a single InMail, and the two numbers below govern how many of them you hold at any moment.

Unused credits transfer into the following month, which is the rollover people ask about. They do not accumulate indefinitely. Your plan's ceiling caps the total, and each credit carries its own 90-day expiry from the point it was granted.

The refill dates differ by product, as the section above sets out, which matters to anyone running both. A credit bought on Premium also stays there: LinkedIn states that Premium InMail credits can't be used to send InMail on Sales Navigator or LinkedIn Recruiter.

The refund rule, precisely

This is the mechanic that changes the arithmetic, and the specifics are more generous than the summary suggests.

LinkedIn returns an InMail credit for every message that receives a response within 90 days of the date it was sent. The credit arrives immediately when the recipient responds.

Refunds your credit

• A direct written reply, of any length
• An automatic reply
• The Interested quick reply, recorded as accepted
• The Maybe later quick reply, recorded as accepted
• The Not interested quick reply, recorded as declined

Keeps your credit spent

• The message is read and ignored
• The message is never opened
• The message stays pending past 90 days
• You delete a message that has not been answered

Read the left column carefully. A recipient hitting "Not interested" is recorded as declined and still returns the credit. So does an out-of-office auto reply. The only outcome that genuinely costs you is being ignored. LinkedIn also sends the recipient an automatic reminder within three days of the send, so the platform resurfaces an unanswered InMail on its own.

That inverts the usual intuition about cold outreach volume. In email, a rejection and a non-response cost the same nothing. Here, a rejection is free and silence is the entire expense, which makes relevance the only lever that moves the budget.

Where credits leak

Four behaviours quietly consume an allowance, and three of them are avoidable.

Sending twice to the same person. On Sales Navigator, a second InMail to someone who has not responded consumes another credit. On Premium the platform simply blocks it until they reply. Either way there is no version where a second attempt is free.

That constraint matches how we run the channel regardless. A LinkedIn thread is permanent, so the second message lands directly underneath the first one they ignored, and it reads as a bump whatever the campaign structure calls it. We do not run no-reply retargets on LinkedIn for that reason. One message, made to count.

Deleting a message. You can edit or delete an InMail within 60 minutes of sending it. If you delete one that has not yet received a response, no credit is returned. Fixing a mistake costs the send.

Spending on Open Profile members. Some Premium members enable Open Profile, which lets anyone message them for free without consuming a credit. Sending a paid InMail to one of them buys nothing.

Cancelling or switching plans. An InMail balance becomes zero when a Premium subscription is cancelled, and credits are not transferable between subscriptions. Banking toward a ceiling before a plan change protects nothing at all.

Planning around the 90-day clock

The expiry rule matters most to the people who think they are being prudent with it.

A common pattern is holding credits back for a quarterly push: skip sending in a quiet month, bank the allocation, then spend the accumulated balance on a campaign later. The ceiling permits it, up to 150 on Sales Navigator, and the 90-day expiry punishes the version of it that runs too long. Credits banked in January and unspent by April are simply gone.

Two habits keep it clean. Spend oldest first where you have the choice, and treat any balance approaching the plan ceiling as a signal that the channel is idle rather than as savings. A full balance is not a war chest. It is three months of unused subscription with an expiry date attached.

Getting more credits

The realistic options are narrower than the marketing implies, and it is worth being blunt about each.

Route	Works?	What LinkedIn's pages say
Buy a top-up on Premium or Sales Navigator	No	You can't purchase additional InMail credits
Upgrade Sales Navigator Core to Advanced	No	All Sales Navigator subscription types provide the same number
Pool Premium credits with a Sales Navigator seat	No	Premium credits can't be used on Sales Navigator
Earn credits back with responses	Yes	A credit for every InMail answered within 90 days
Message Open Profile members	Yes	You can message them for free
Add seats	Partly	Each Sales Navigator user is allocated 50 a month

The two "no" answers at the top are the ones worth internalising. LinkedIn states that additional InMail credits cannot be purchased outside the monthly allotment, and that all Sales Navigator subscription types provide the same number of credits. Upgrading from Core to Advanced buys research and collaboration features, covered in the Sales Navigator pricing guide, and changes your messaging capacity by zero.

Recruiter and Recruiter Lite run their own allotment per licence, and LinkedIn's Recruiter help page shows where to see the credits left, the credits expiring and the amount granted on the refresh date. Those are hiring products with their own contract, separate from the sales ones.

Adding seats works arithmetically and is the honest answer for teams, but each seat is a real subscription with a real cost, and the per-seat account limits come with it.

Auditing your own consumption

The balance is visible in three places, and they answer slightly different questions.

The compose window shows your remaining credits while you write, which is the check to make immediately before a send. On Premium, the My Premium page shows your current balance, your renewal date and your monthly allocation together. On Sales Navigator, the settings page carries the remaining count.

What none of them show is the number that matters, which is how many of your sends came back. Track it yourself, monthly, per seat: messages sent, responses received inside 90 days, and the closing balance. Net consumption is sends minus refunds, and comparing it to your allocation tells you what your real capacity is rather than what the plan advertises.

A seat that consistently ends the month at zero is not a seat that needs a bigger plan, because no bigger plan exists on the sales products. It is a seat whose messages are not landing, and the fix is upstream of the credit system entirely.

The number that actually constrains you

Teams reach for more credits when the allowance runs out, and a depleted allowance is usually a symptom rather than the problem.

Because responses refund credits, running dry means a large share of your sends went unanswered. Buying more capacity at that response rate multiplies the spend and returns the same result. The cheaper move is to send fewer, better-targeted messages, which both raises the response rate and refunds more of what you spend.

Credits are also not the only limit on a seat. A seat with credits available can still be an account doing too much, and the LinkedIn automation tools guide covers the account-level thresholds that matter most when software is sending on your behalf.

What this means in practice

Treat the monthly 50 as a budget for conversations rather than a quota of messages to clear. A team getting responses on half its sends effectively has closer to 100 attempts a month on one seat, and a team getting responses on a tenth of them has 55 and a reputation problem.

The pre-send checks are boring and they are the whole game: is this person still in the role, is Open Profile off, is there a reason to write today, and would this first line be nonsense sent to anyone else on the list. Every one of those is free to verify. For the rest of the mechanics, the complete InMail guide covers character limits and the send flow, and what InMail costs per reply turns the refund rule into actual money.

We run LinkedIn alongside email for clients on a pay-per-qualified-meeting basis, which puts the targeting discipline on our side of the line. You can see what a campaign would look like for your market before buying seats to find out.

InMail credit allowances, accumulation ceilings, refund rules and renewal timing are taken from the LinkedIn Help Center. LinkedIn revises these; verify current terms with LinkedIn before relying on them.
