How to Get More LinkedIn InMail Credits (7 Real Methods)

Why You're Always Running Out of InMail Credits

If you're using LinkedIn for outbound sales or recruiting, you already know the feeling: you've got a list of solid prospects, you've written a good message, and then you hit the wall. Out of credits. Again.

LinkedIn's InMail credit system is deliberately constrained. Premium Career gives you just 5 credits per month. Premium Business gives you 15. Sales Navigator - the plan most serious sales reps and recruiters are on - gives you 50 per month across all plan tiers, with a rollover cap of 150 total. Recruiter Lite comes with 30 per month. Full LinkedIn Recruiter gives you 150 per month.

At roughly $10 per credit when purchased standalone, burning through your allocation on unresponded cold messages is an expensive problem. So let's fix it - starting with how the system actually works, then moving into every lever you can pull.

How LinkedIn InMail Credits Actually Work (The Rules Most People Miss)

Before you try to get more credits, you need to understand exactly how the system operates. There are a few mechanics that catch people off guard.

Rollover and accumulation caps. Unused credits roll over month to month, but there's a hard ceiling on how many you can stockpile. Premium Career caps at 15 total. Premium Business caps at 45. Sales Navigator caps at 150. Recruiter Lite caps at 120. Once you hit the cap, new monthly credits stop adding to your balance until you spend some down. The practical implication: if you've been sitting on a Sales Navigator account for months without sending InMails, you're already at your 150-credit ceiling - you haven't been banking credits beyond that.

Credit refunds when people reply. This is the single most important mechanic to understand. Every InMail that receives any response within 90 days - accepted, declined, or a direct reply - gets that credit returned to your account automatically. There's no claim process; it happens on its own. Even a "not interested" response earns you the credit back. The only way you permanently lose a credit is if your message gets completely ignored.

You cannot send a second InMail until someone responds. LinkedIn locks you out of messaging the same person again until they've responded to your first message. An automatic reminder does go out to the recipient within three days of your send, but after that, you're waiting. This is another reason your response rate matters so much - low reply rates don't just waste credits, they lock you out of following up with targets who might have responded to a different approach.

Character limits. Subject lines cap at 200 characters. Message bodies cap at 1,900 characters. That's actually more room than most people use well. Most high-performing InMails are far shorter than the limit - treat the cap as a maximum, not a target.

Credits disappear if you cancel or downgrade. If you cancel your LinkedIn Premium subscription, your entire InMail balance drops to zero immediately. If you downgrade to a lower plan tier, any credits above the new plan's accumulation cap are also lost. Plan around this if you're considering a subscription change.

Premium InMail credits don't cross platforms. Credits from a regular LinkedIn Premium Career or Business account cannot be used to send InMails within Sales Navigator or LinkedIn Recruiter. Each product's credit pool is separate.

Method 1: Earn Refunds by Getting Replies

This is the most underused lever, and it's built directly into LinkedIn's system. If a recipient responds to your InMail within 90 days - even if they just say "not interested" - you get that credit back. A declined InMail still earns a refund. A full reply earns a refund. The only way you lose the credit permanently is if your message goes completely ignored.

That means your response rate directly controls your effective credit budget. A 40% reply rate on 50 InMails effectively gives you 70 usable touches per month, not 50. Push that to 60%, and you're closer to 80. The math compounds fast.

LinkedIn's own benchmarks suggest that well-crafted InMail campaigns can hit 20-25% response rates. Top campaigns push even higher. The gap between a 10% reply rate and a 30% reply rate on a 50-credit budget is the difference between recovering 5 credits and recovering 15. Over a quarter, that gap adds up to dozens of extra usable touches without paying for anything additional.

To maximize refunds:

• Write personalized subject lines. Generic "Quick question" subject lines get ignored. Reference something specific from their profile, a recent post they made, or a company milestone. Specific beats clever every time.
• Lead with value, not your pitch. The first sentence should make the reader feel like this message is for them specifically. Tell them why you're reaching out and what's in it for them - fast.
• End with a low-friction CTA. "Worth a quick chat?" or "Does this apply to what you're working on?" gives them an easy yes or no. An easy no still gets you your credit back.
• Keep it short. InMails under 400 characters tend to get better response rates on mobile. Respect their time. The 1,900-character limit is not an invitation to write an essay.
• Send mid-week. Engagement on LinkedIn tends to peak mid-week when professionals are in work mode. Avoid Friday afternoons and Monday mornings.

If you want a proven LinkedIn outreach framework, grab the LinkedIn Playbook - it walks through exactly how to structure messages that actually get replies.

Method 2: Target Open Profiles (Free InMails)

Most people don't know this exists. LinkedIn Premium members can enable an "Open Profile" setting that allows anyone - even free-account users - to send them an InMail without spending a single credit. You can identify these profiles by the gold LinkedIn badge next to their name. Note that the gold badge indicates Premium membership, but not every Premium member has the Open Profile setting enabled - some have turned it off.

The ceiling on these free Open InMails is high - some estimates put it at up to 800 per month. That dwarfs the 50 credits you get on Sales Navigator. If a significant portion of your prospect list is made up of LinkedIn Premium users - which is common in enterprise sales, recruiting, and B2B SaaS markets - you can systematically route outreach to Open Profiles first and save your paid credits for everyone else.

On Sales Navigator, you can actually filter search results to show only Open Profiles, which makes it easy to build a dedicated outreach list of prospects you can message for free. On standard Premium accounts, this filter is no longer available, but you can still check individual profiles manually or attempt to send and see whether the credit is consumed.

The manual version of this is slow: visit each profile, check for the open badge, then send. The faster approach is to use a LinkedIn automation tool like Expandi or Drippi that can detect open profiles automatically and route messages accordingly without burning credits.

Method 3: Purchase Additional Credits (Recruiter Lite Only)

This one applies specifically to Recruiter Lite users and is worth calling out because it's the only plan where LinkedIn actually lets you buy extra credits beyond your monthly allotment.

On Recruiter Lite, your Purchaser Admin can buy additional InMail credits in packs of 10, up to a maximum of 70 additional credits per seat per billing cycle. The hard ceiling is 120 InMails per seat total - that includes your monthly allotment plus any purchased credits combined. So if you already have 80 credits sitting in your account, you can only buy up to 40 more before hitting the cap.

The steps: go to your Recruiter Lite homepage, hover over your profile picture and select Product Settings, click Manage Account, then click Purchase next to "Purchase InMail credits," enter your pack quantity (sold in tens, max 70), and complete payment. Credits are added automatically once the transaction is done.

Important: This option does not exist for Sales Navigator. LinkedIn is explicit that you cannot purchase additional InMail credits on Sales Navigator - your only options there are to upgrade your plan tier or earn refunds through replies. If you're on Sales Navigator and looking to buy more credits, you're out of luck on that front. The only native path to more volume is a plan upgrade or better reply rates.

Method 4: Message Group Members and Event Attendees for Free

Two completely free LinkedIn features that almost nobody uses for outreach:

LinkedIn Groups: If you share a LinkedIn Group with a prospect, you can message them directly without a connection request and without spending an InMail credit. This works even for 2nd and 3rd-degree connections. Find or join 3-5 active groups where your buyers hang out, and you've unlocked a free messaging channel with anyone in those groups. The catch: your message lands in their Message Requests folder rather than their main inbox, so your subject line and opening line need to earn a click.

LinkedIn Events: Register for a relevant LinkedIn Event and you can message other attendees for free. Industry webinars, virtual summits, and niche conferences often have exactly the kind of decision-makers you're trying to reach. Register, then work the attendee list. The same Message Requests caveat applies, but a contextual opener ("I also registered for [Event Name] and noticed your work at...") earns the click more often than a cold message from nowhere.

Neither of these requires a premium plan. Both are massively underused. If you're systematic about it - joining 4-5 relevant groups and registering for a few active events in your niche each month - you can unlock a free outreach channel that runs completely parallel to your credit-based InMail spend.

Method 5: Start a Free Trial (If You Haven't Used One Recently)

LinkedIn offers free trials for Sales Navigator and Premium Career. When you start a trial, LinkedIn loads your account with the full monthly InMail credit allocation for that plan. LinkedIn restricts free trials to members who haven't been on any paid LinkedIn subscription recently, so this isn't a repeatable hack - but if you're new to a plan or between subscriptions, it's worth knowing the credits come with the trial and are usable immediately.

This is most useful if you're evaluating Sales Navigator for the first time and want to run a real outreach test before committing to the annual subscription. Use the trial period to send a batch of InMails, measure your reply rate, and decide whether the channel justifies the cost before you pay for it.

Method 6: Upgrade Your Plan

Straightforward but worth laying out clearly. If InMail is a core part of your prospecting motion, the jump from Premium Business (15 credits/month) to Sales Navigator Core (50 credits/month) is significant. Full LinkedIn Recruiter accounts come with 150 credits per month, and on corporate Recruiter plans, those credits are pooled across team members - meaning if one recruiter has a slow month, another can draw from the shared allocation.

LinkedIn's official position is clear: you cannot purchase standalone InMail credits on Sales Navigator. The only way to increase your hard cap on that plan is to upgrade your plan tier. So if you've maxed out your 150 accumulated credits and still need more volume, a plan upgrade is the only native option LinkedIn gives you.

One thing to watch: credits are not transferable when you upgrade. If you move from Premium Business to Sales Navigator, your existing Premium credits don't carry over into the new platform's pool. That's a fresh start, so don't let it catch you off guard on a campaign timeline.

Method 7: Stop Using InMail for Everything

This sounds counterintuitive but it's the most important mindset shift. InMail is a premium-priced channel. Using it for every prospect in your pipeline is like flying business class for every sales call - it burns budget fast with no proportional return.

The smarter play: use InMail strategically for your highest-value targets only. For everyone else, there are better, cheaper, and often more effective alternatives:

• Personalized connection requests: A well-written connection request note that gets accepted converts a stranger into a 1st-degree connection, after which you can message them for free indefinitely. Connection request notes are limited to 300 characters - short enough that you have to be specific, which actually helps. This is often the best first move before any paid outreach.
• Cold email: If your prospect is a VP at a mid-market company, their work email is findable. Email gives you no credit limits, no rate caps, and the ability to run proper sequences. For finding those emails at scale, this B2B lead database lets you filter by job title, seniority, industry, and company size to pull clean prospect lists fast - no credits required.
• LinkedIn voice notes: If you're already connected, a voice note stands out dramatically over text. Grab the LinkedIn Voice Note Script for a proven template.
• Phone outreach: For your highest-priority accounts, a direct dial puts you ahead of every InMail in their inbox. If you need to find mobile numbers for prospects, a direct dial finder can pull cell and direct numbers for contacts by name and company.

Tools like Smartlead and Instantly let you run cold email sequences at scale, completely separate from LinkedIn's credit system. The combination of connection requests + cold email + selective InMail use will almost always outperform going all-in on InMail alone.

Tools like Lemlist and Reply.io also support multichannel sequences that blend LinkedIn steps with email and phone touches - so you can slot InMail into a broader sequence rather than treating it as a standalone channel.

Method 8: Write Better InMails So Fewer Credits Disappear

Every ignored InMail is a permanently lost credit. That's the tax on lazy outreach. So the single highest-ROI thing you can do isn't finding more credits - it's making sure the credits you do have convert.

A few things that consistently move the needle:

• Reference something real. A recent post, a funding announcement, a job change. Show them you actually looked at their profile. Generic openers get deleted without a second thought.
• One ask, not three. Don't ask for a call, a demo, and a referral in the same message. One CTA. Make it easy to say yes or no.
• Subject line matters more than you think. It's what determines whether the message gets opened at all. Treat it like the subject line of a cold email - specific beats clever. "Quick question about your agency's outbound" outperforms "Connecting" every time.
• Follow up once. A single follow-up five to seven days later is worth sending. Keep it to one line with new context. After that, move on - a second follow-up uses another credit and rarely improves your odds meaningfully.
• Use Quick Replies to your advantage. LinkedIn's Quick Reply buttons ("Interested," "Maybe later," "Not interested") count as responses and trigger credit refunds. Structuring your message so it ends with a natural yes/no framing increases the chance someone hits a Quick Reply button, which gets you the credit back even if the answer is no.

How to Check Your Remaining InMail Credits

Simple but worth covering since it comes up constantly. There are three places to check:

• In the compose window: Open any InMail compose window for a prospect you're not connected with. Your remaining credit count is displayed at the top of the message box before you start writing.
• In your Premium settings: Click your profile picture, go to Premium Features, scroll to the InMail Messages tab. Your available balance shows there.
• In Sales Navigator settings: Your credit count appears in the profile dropdown inside Sales Navigator. LinkedIn also sends a notification when credits are running low, though by the time you get that notification you're usually already close to empty.

If you're managing a team on LinkedIn Recruiter, the shared pool balance is visible in the Usage Overview section under Product Settings. This is where you can also see which team members are consuming the most credits and whether the response rates justify the usage.

InMail vs. Connection Requests: When to Use Each

One of the most common mistakes I see is people defaulting to InMail when a connection request would work just as well - and cost nothing. Here's how to think about which to use:

Use a connection request when: The prospect is likely to recognize your name or company. You have a mutual connection or shared group membership. The prospect is active on LinkedIn (recent posts, activity). You're in early prospecting mode and want to warm them up before spending a credit. Connection requests are free, allow a 300-character note, and if accepted, open up free messaging permanently.

Use InMail when: The prospect has a locked profile or hasn't accepted connection requests from your industry. The deal value is high enough to justify the per-message cost. You've already tried a connection request and it went unanswered. You need a more formal, longer message than a connection request note allows.

The practical rule: exhaust free channels first. Connection request, Group message, Event attendee outreach. InMail is the closer, not the opener, for most outreach sequences.

The Bigger Picture: Don't Build Your Pipeline on a Credit System

LinkedIn InMail is a good channel. But it's a constrained, expensive one. The reps and agencies doing serious volume - booking 20, 30, 50+ meetings a month - are not doing it on 50 InMails. They're running multichannel sequences: connection request, then email, then InMail if needed, then maybe a phone call.

If you want to build that kind of pipeline consistently, you need contact data that lives outside LinkedIn's walled garden. An email finding tool that works off a prospect's name and company domain gives you a cold email channel with no monthly caps and no credit system to manage. That's the kind of outreach infrastructure that scales.

Use InMail credits for what they're actually good at: reaching high-value prospects who are unlikely to accept a cold connection request and whose business justifies the per-message cost. Reserve them like they're expensive, because they are. Build the rest of your pipeline through channels that don't run out.
