In short
- 1"Connection requests reply at 7.9-12.2% vs InMail's 6.38%, and they are free rather than about $2.40 a credit on a Sales Navigator Core seat billed monthly"
- 2"InMail only wins when prospect acceptance rates fall below 15%, typical for C-suite at large enterprises"
- 3"Every Sales Navigator tier includes 50 InMail credits a month; 150 is the rollover ceiling, not a bigger allowance"
- 4"Sales Navigator sells no InMail top-ups (LinkedIn Help, checked August 2026), so 200 all-InMail prospects needs 4 Core seats at $119.99 billed monthly, about $480, against one seat for the hybrid"
InMail costs about $2 a message. Connection requests are free. The reply rates aren't even close.
This should be a simple decision. Belkins' 2026 study of roughly 15 million LinkedIn outreach touchpoints found that warm messenger campaigns (messaging people you are already connected to) reply at 12.2%, while cold connector campaigns (connection request first, then a message) reply at 7.9%. InMail, by comparison, sits at a 6.38% reply rate, measured across Expandi's 2024 dataset of more than 20 million outreach attempts. Even the cold connection path beats it.
GrackerAI's analysis points the same way: personalized connection-based sequences reach a 39% positive reply rate (a figure GrackerAI credits to SalesBread), versus 18-25% for InMail.
And InMails cost money. Every Sales Navigator tier, Core and Advanced alike, includes 50 InMail credits per month; unused credits roll over for up to three months to a ceiling of 150, which is an accumulation cap rather than a bigger monthly allowance. That is where the "about $2 a message" figure comes from: a Sales Navigator Core seat is $119.99 per user per month billed monthly, per LinkedIn's compare-plans page checked in August 2026, so 50 included credits work out to roughly $2.40 each, or about $1.80 each on annual billing at roughly $90 per user per month. Once the included credits run out you cannot top up: LinkedIn's Sales Navigator help states plainly that you cannot purchase additional InMail credits (LinkedIn Sales Navigator Help, "Understand InMail credits in Sales Navigator", checked August 2026), so a Core seat is capped at 50 a month plus whatever it has banked toward the 150 accumulation ceiling. Connection requests are free, capped only by LinkedIn's weekly connection request limits. The seat price behind those credits, including the annual-billing math and the trial clauses, is broken down in Sales Navigator pricing, plan by plan.
So why does anyone still use InMail?
Because there's one scenario where the math flips - and understanding that scenario is the real insight.
When connection requests win (most of the time)
For the majority of LinkedIn outreach, connection requests outperform InMails on every metric.
The numbers
The core advantage of connection requests isn't just the higher reply rate. It's that accepting a connection creates a permanent relationship. Once connected, you can message them for free, see their posts in your feed, and engage with their content over time. InMail is a single interaction with no lasting connection.
Why connection requests perform better
Less friction. A connection request is a small commitment - "sure, I'll add this person." An InMail demands attention and a response. Psychologically, the bar is lower.
Social proof. Connection requests show mutual connections, shared groups, and your profile directly. InMails feel more like ads landing in a separate inbox.
Follow-up access. After connecting, your follow-up messages appear in their regular inbox, not the InMail folder that many people ignore. Expandi's 2026 State of LinkedIn Outreach report shows messenger campaigns to existing first-degree connections replying at 16.86%, the best-performing campaign type in its data and far above InMail.
The warm-up advantage
When you warm a prospect up with a profile visit and light engagement before connecting, you move them toward the warm-messenger tier that replies at 12.2%, versus 7.9% for cold connector outreach (Belkins 2026). There is no equivalent warm-up mechanism for InMail. The profile visit creates an "I have seen this person before" effect that makes the connection request feel natural.
When InMail wins (the executive exception)
Senior executives - C-suite, VPs at large enterprises - have a different LinkedIn experience from the rest of us. They get dozens of connection requests daily, and their acceptance rate for unknown senders often runs below 10%, well under the typical connection acceptance rate benchmarks.
For this audience, InMail can outperform because:
It bypasses the connection gate. You don't need them to accept you first. The message arrives directly, regardless of whether they'd accept a connection request.
Executives check InMail differently. For people who receive constant connection requests, InMail stands out as a more intentional (and paid) form of outreach. Some executives perceive InMails as more serious precisely because they cost money.
The math changes at low acceptance rates. If connection request acceptance for your target audience is 8%, and roughly a quarter of the people who accept go on to reply, your effective outreach-to-reply rate is about 2% overall. A well-targeted InMail at the top of its 18-25% range wins easily.
The InMail sweet spot
Use InMail when:
- Targeting C-suite or VP-level at Fortune 500 companies
- Connection request acceptance rate for your audience is below 15%
- You need to reach someone urgently (no time for the warm-up sequence)
- The prospect has "Open Profile" status (InMail is free to open profiles)
Check for Open Profiles first. LinkedIn lets you send free InMails to members with open profiles. For some audiences a meaningful share have this enabled, meaning you don't need credits at all.
The hybrid approach that outperforms both
The highest-performing teams in the GrackerAI and Belkins data don't choose one or the other. They use a sequence:
The sequence
- Day 1: Visit the prospect's profile
- Day 2-3: Engage with their content (like or comment)
- Day 4: Send connection request (without note)
- Wait 5-7 days
- If accepted: Send personalized first message (this is the step that carries the reply rate, and a well-warmed first-degree message is the best-performing message type in Expandi's 2026 data at 16.86%)
- If not accepted after 7 days: Send InMail as fallback
This approach uses connection requests as the primary channel (free, higher reply rates, builds lasting relationship) and InMail only as a fallback for prospects who don't accept. You're spending InMail credits only on the hardest-to-reach prospects, not wasting them on people who would have accepted a free connection request.
Why the sequence works
The warm-up steps (profile visit, content engagement) increase both connection acceptance rates and InMail reply rates. A prospect who's seen your name twice before getting your InMail is more likely to respond than one who's never heard of you.
Tools like BeReach help you run this exact sequence and turn more of your list into replies - profile visits, engagement, connection requests, and follow-up messaging, all timed around the prospect's behavior. The BeReach agent handles the warm-up and routing for you, falling back to InMail only when connection requests don't get accepted.
The cost analysis most people skip
InMail pricing looks reasonable until you do the math at scale.
Scenario: 200 prospects per month
Sales Navigator Core is priced at its monthly-billed rate of $119.99 per user per month below.
LinkedIn does not sell extra InMail credits for Sales Navigator, so reaching 200 InMails in a month means paying for four Core seats. All-InMail is still the most expensive path by a wide margin, roughly 4 times the cost of the hybrid for a similar number of replies. Connection requests are free and leave you with lasting first-degree connections, a long-term asset InMail never creates.
Every viral post is 100+ warm conversations waiting.
Tell your agent who you want to reach. It finds them, says which ones are worth your time, writes the first line, and follows up.
Frequently asked questions
Is InMail or a connection request better for LinkedIn outreach?
Connection requests are better for most outreach. They're free, reach higher reply rates (7.9% cold to 12.2% warm per Belkins 2026, versus 6.38% for InMail per Expandi 2024), and create lasting connections. InMail wins only for senior executives at large companies who accept fewer than 15% of connection requests. The best approach is a hybrid: connection request first, InMail as fallback for non-acceptors.
What is the average InMail response rate?
InMail campaigns average a 6.38% reply rate in Expandi's 2024 dataset of more than 20 million outreach attempts. Other sources report higher ranges (18-25%) depending on personalization quality and audience. Personalized InMails targeting open profiles perform best. Generic InMails to cold prospects perform worst. For context, Belkins' 2026 study of roughly 15 million touchpoints puts warm messenger campaigns at 12.2% and cold connector campaigns at 7.9%, both above InMail. The range is wide because InMail performance is highly sensitive to targeting and message quality.
Should I include a note with my connection request?
For acceptance, it barely matters. Belkins' 2026 study found 27.6% acceptance without a note versus 25.3% with one, so the blank request actually edges ahead. Where personalization pays off is replies: the same study measured 8.2% for noted requests against 5.3% for bare ones once the connection was live. Free accounts are also limited to roughly 5 noted requests per month, so put your best effort into the message that gets read, whether that is the note or your first message after connecting. Notes help most when you have a genuine shared connection or context to reference.
Can I send InMail for free?
Yes, to prospects with Open Profile status. Open Profile is a Premium subscriber setting, so only prospects on a paid LinkedIn plan can switch it on to receive InMails without the sender spending a credit (LinkedIn Help, "Manage your Open Profile settings as a Premium subscriber", checked August 2026). Free and Basic senders are also capped at a limited number of Open Profile messages a month. Check before spending a credit, and you can earn credits back when InMail recipients reply within 90 days.
