Sales Navigator InMail Credits: How Many You Get, and Which Accounts Earn One

The short answer

I'm Hlib Storchak. I build and run LinkedIn and cold email outbound for B2B founders and sales teams, 2000+ meetings booked for clients along the way, and the "am I wasting my InMail credits" question comes up almost every time a client has been running Sales Navigator for more than a month. The direct answer: you get 50 InMail credits a month no matter which Sales Navigator tier you're on, Core, Advanced, or Advanced Plus. That's confirmed directly on LinkedIn's own Sales Navigator account types page and its Advanced Plus overview page separately. A higher tier buys you more filters, Buyer Intent data, and team features. It does not buy you a bigger InMail allowance.

What most people actually want to know once they have that number is what it means in practice: what happens to credits you don't use, when you get one back, and which of your accounts are actually worth spending one on. That's the rest of this guide.

How the monthly allotment actually works

LinkedIn adds a fresh batch of credits to your account on the first of each month, per its own InMail credits and renewal process help page. You can't buy extra credits on top of your plan's monthly allotment, there's no add-on purchase for this the way there is for some CRM seats or data credits. Whatever you don't spend this month, you keep, up to the cap covered below. There's no partial-month proration either: if you upgrade or add a seat mid-cycle, the new allotment follows LinkedIn's normal renewal timing rather than a prorated top-up.

InMail credits by tier, side by side

Here's how the credit allowance compares across LinkedIn's paid tiers, including the cheaper Premium Business plan people sometimes confuse with Sales Navigator:

Both columns come directly from LinkedIn's own help center, not a reseller's recap. For what each Sales Navigator tier costs and the full feature breakdown behind the price, I've covered that separately in Sales Navigator pricing plans, since the credit allowance is identical across all three and the tier decision really comes down to filters, seats, and CRM sync instead.

The 150-credit cap, and what LinkedIn doesn't publish

Credits roll over, but only up to 150 banked at once for a Sales Navigator seat, per the same LinkedIn help page. That's three months of unused allowance sitting in reserve. What LinkedIn's own documentation does not spell out is what happens to your next monthly batch once you're already sitting at that ceiling, whether the new credits are simply lost, whether the oldest ones get pushed out first, or something else. I looked for a direct answer on LinkedIn's own pages and couldn't find one stated anywhere I'd trust enough to repeat as fact, so I'm not going to guess at a mechanism it hasn't published.

What that uncertainty means practically: treat 150 as a ceiling you don't want to test, not a safe buffer. If you're regularly running close to it, that's a sign you're under-spending your credits relative to what the seat is actually priced for, not a sign you're being disciplined.

When a sent credit actually comes back to you

This is the detail most "how many InMail credits do I get" searches miss entirely, and it's the one that actually changes how you should spend them. Per LinkedIn's own help page, a sent InMail credit is returned to your balance if the recipient accepts it, declines it, or responds to it directly, and only if that happens within 90 days of you sending it. A message that's never opened, or opened and ignored, is neither accepted nor declined. It doesn't trigger a refund. The credit is simply gone, with nothing to show for it.

That reframes what you're actually risking every time you send one. It isn't "50 InMails a month." It's closer to "50 messages a month that someone can ignore before it starts costing you anything you'll actually feel," because every response, even a flat no, gives the credit back. The expensive outcome isn't rejection, it's silence.

Why this is a scarce resource, not a sending channel

Compare that to cold email, where the real constraint is inbox count and warmup stage rather than a fixed monthly allowance. I've laid out the actual safe sending range per inbox in how many cold emails per day per inbox, and the short version is that email volume scales by adding more properly warmed inboxes, there's no hard ceiling LinkedIn-style. InMail doesn't work that way. You can't buy more credits, you can't warm your way to a higher allotment, and a second Sales Navigator seat just gives you a second 50, not a shared, larger pool. That structural difference is exactly why InMail needs a spending rule and cold email mostly needs a volume plan.

It's also why I'd never recommend treating InMail as a first-touch channel for a cold list the way you might with email or a connection request. A connection request costs nothing but a 300-character note and some patience. An InMail that goes nowhere costs you one fiftieth of your month.

A decision framework: which accounts earn a credit

Before you spend one, I'd check an account against these, roughly in this order:

1. Is a free connection request actually off the table? If you share a group, an alumni network, or a mutual connection worth mentioning, send a connection request first. InMail is for when that path genuinely doesn't exist, 2nd or 3rd-degree, no shared ground to request through.
2. Is this a named decision-maker, not a generic title match? A credit spent on a specific person you've researched, not a job-title filter result, is a different bet than a credit spent on "anyone who looks like a VP of Sales."
3. Does the account carry above-average deal value or strategic weight? Save credits for the accounts where a meeting is worth meaningfully more than your average deal, not spread evenly across your whole list.
4. Is there a real reason to reach out now? A hiring signal, a funding round, a role change, something that makes the message read as timely rather than generic. I've covered how to build a list around exactly this kind of signal in how recruitment agencies find clients without referrals, and the same logic for spotting a real trigger applies here.
5. Can you write something a stranger would actually answer? If the honest draft reads like a template with their first name dropped in, that's a flat no-reply risk, and per the refund rule above, a no-reply is the one outcome that actually costs you.

A simple scoring model, before you hit send

If a checklist feels too loose for your team, here's a cost model you can run with your own weighting rather than mine. Score each candidate account:

• +2 if a free connection request path doesn't exist (2nd/3rd-degree, no shared group or mutual).
• +2 if it's a named, researched decision-maker rather than a title-filter match.
• +1 if the account's deal value sits above your own average.
• +1 if there's a specific, current reason for the outreach (a hiring signal, a role change, a funding event).
• -2 if the draft you'd actually send is a generic template with a name swapped in.

Spend the credit at a score of 3 or higher. Hold it below that, and either strengthen the research first or route the account through a free connection request instead. The weighting is mine, built from what I watch actually convert for clients, not a researched formula, swap in your own numbers once you've tracked a month or two of your own results against it.

Mistakes that quietly waste credits

The same handful of mistakes show up across most accounts I audit:

• Using InMail as a default first touch on a cold list. If a connection request would have reached the same person for free, the credit bought nothing a cheaper channel wouldn't have.
• Sending a generic, title-matched pitch and hoping volume covers for quality. Per the refund rule, a generic message that gets ignored is the single most expensive outcome available, worse than an honest no.
• Not tracking which credits actually came back. Most teams know they "have 50 a month" and stop there. Few track their own accept/decline/reply rate well enough to know their real effective monthly volume, which is usually higher than 50 once refunds are counted in.
• Letting the balance run up toward 150 out of caution. A large unused balance isn't a safety net, given LinkedIn hasn't published what happens once you're at the cap, it's untested risk sitting on your account for no benefit.

What I actually tell clients to do with theirs

The setup I run for clients is a simple shared log, one row per InMail sent: account, score from the model above, date, and outcome (accepted, declined, replied, or silent). It takes thirty seconds per send and it's the only way I've found to actually see a team's real refund rate instead of assuming it. The pattern I see most often when I take over an account that's never tracked this: a far higher silent-ignore rate than the person sending expected, usually because credits were going to title-filtered lists instead of the researched, timely sends the framework above calls for. Fixing just that, without changing volume at all, is usually the single biggest lever on how far 50 credits actually stretch.

Where this sits next to the rest of your LinkedIn plan

InMail credits are one small piece of what a Sales Navigator seat actually does, and it's worth zooming out before you over-optimize this one number. If you're still deciding whether the seat is worth it at all for a smaller team, I've built that exact breakeven math in is Sales Navigator worth it for a small business. For how InMail stacks up against connection requests and cold email as channels, not just as a credit line, see InMail vs connection request vs cold email. And if you're curious why LinkedIn enforces a published response-quality bar on Recruiter seats but nothing comparable on Sales Navigator's InMail, I've dug into that gap directly in LinkedIn's Recruiter InMail policy vs Sales Navigator.
