In short
- 01"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"
- 02"InMail only wins when prospect acceptance rates fall below 15%, typical for C-suite at large enterprises"
- 03"Every Sales Navigator tier includes 50 InMail credits a month; 150 is the rollover ceiling, not a bigger allowance"
- 04"Replace the line 23 tldr bullet with a seat-based figure that does not assume a top-up LinkedIn does not sell, keeping tier, billing basis, and a dated citation inside the bullet itself since the tldr gets lifted without surrounding context:
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. Replace the final cost sentence at line 32 with: "Once the included credits run out you cannot top up. LinkedIn's Sales Navigator help states plainly that "you can't purchase additional InMail credits" (LinkedIn Sales Navigator Help, checked August 2026), so a Core seat is capped at 50 a month plus whatever it has banked toward the 150 accumulation ceiling. The $21-per-credit rate LinkedIn moved to in October 2025, up from $3, is a Recruiter charge rather than a Sales Navigator one, and LinkedIn Recruiter Help says extra credits there sell in packs of 10, up to 70 per seat." Do not cite the Recruiter help page for the $21 figure itself; that page states the pack structure and per-seat caps but no price, so source the price separately or attribute it as LinkedIn's October 2025 repricing of purchasable Recruiter credits. Keep the earlier part of line 32 unchanged, since the $119.99 Core monthly rate, the roughly $2.40 per included credit, and the roughly $1.80 on annual billing are all correct. Four dependent lines must be swept in the same edit or the page contradicts itself: line 23 (tldr) should drop "$21 an extra credit" and say a Core seat is hard-capped at 50 InMails a month with no top-up available; line 48 (table, cost-per-message row) should read "About $2.40 a credit inside a Sales Navigator Core seat billed monthly, about $1.80 billed annually, and no top-up available once the 50 are gone"; line 121 (the 200-prospect scenario) should state that all-InMail is not merely expensive but impossible on Sales Navigator, since 200 messages a month cannot be bought at any price on a Core seat, which caps the honest comparison at the 50 included credits (or 150 if fully banked); and line 125 should replace "roughly 27 times the cost of the hybrid" with the stronger and now-accurate point that the all-InMail path is unavailable on Sales Navigator rather than just costlier. Connection requests are free, capped only by LinkedIn's weekly connection request limits.
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.
| All InMail (200 messages) | Not purchasable as a top-up: Sales Navigator sells no additional InMail credits (LinkedIn Sales Navigator Help, checked August 2026), and each seat gets 50 a month, so 200 InMails in one month means 4 Core seats at $119.99 a month billed monthly = ~$480 | 200 x 6.38% = ~13 replies |
Four dependent lines must move with it, or the page contradicts itself:
- Line 125: "roughly 27 times the cost of the hybrid" was $3,270/$119.99. With ~$480 against one $119.99 seat it is roughly 4 times. Rewrite as "roughly 4 times the cost of the hybrid", and drop "Since LinkedIn's October 2025 credit hike," as the causal opener since the hike no longer drives this number.
- Line 23 (tldr): "200 all-InMail prospects costs ~$3,270/month after LinkedIn's October 2025 hike to $21 an extra credit, vs the $119.99 Sales Navigator Core seat billed monthly for the hybrid" becomes "Sales Navigator sells no InMail top-ups, so 200 all-InMail prospects means 4 Core seats at $119.99 billed monthly, about $480, vs one seat for the hybrid".
- Line 32: "Once the included credits run out, LinkedIn charges $21 for each additional credit, up from $3 before its October 2025 hike" is false for Sales Navigator. Either cut it or scope it: "Sales Navigator sells no additional credits at any price; when the 50 run out you wait for the next month. The $21-an-extra-credit figure that circulates after LinkedIn's October 2025 hike, up from $3, belongs to Recruiter, a separate product, where top-ups are capped at 70 extra and 120 total per seat."
- Line 48 (comparison table, cost-per-message cell): delete the trailing ", $21 per extra credit" so the row reads "About $2.40 a credit inside a Sales Navigator Core seat billed monthly, about $1.80 billed annually, and no top-ups sold".
Leave the summary/description frontmatter ($2.40 and $1.80 per credit) alone, that arithmetic is unaffected. | All connection requests | Free (connection requests need no paid plan) | 200 x 26% accept x 25% reply = ~13 replies | | Hybrid (connections first, InMail fallback) | ~40 fallback InMails fit inside the 50 included credits, so just the Sales Navigator Core seat at $119.99 a month billed monthly | ~13 from connections + ~3 from InMail = ~16 replies |
Replace line 125 with: "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."
This edit is only safe as part of one pass that also removes the same refuted premise from the four other places it appears, or the page contradicts itself:
- line 23 (tldr): drop the "~$3,270/month after LinkedIn's October 2025 hike to $21 an extra credit" claim, e.g. "200 all-InMail prospects needs four Sales Navigator Core seats at $119.99 billed monthly, because LinkedIn does not sell extra InMail credits, versus one seat for the hybrid".
- line 32: replace "Once the included credits run out, LinkedIn charges $21 for each additional credit, up from $3 before its October 2025 hike." with "Once the included credits run out you cannot buy more: LinkedIn's Sales Navigator help centre states you can't purchase additional InMail credits, so the only way to raise your ceiling is another seat."
- line 48 (Cost per message cell): drop ", $21 per extra credit" and end at "about $1.80 billed annually".
- line 121 (all-InMail row): reprice as "4 Sales Navigator Core seats at $119.99 a month billed monthly = ~$480, because extra credits cannot be bought".
Cite LinkedIn Sales Navigator Help, "Understand InMail credits in Sales Navigator", checked August 2026, for the no-purchase rule. Avoid asserting four seats is literally "the only way", since the article elsewhere notes Open Profile InMails are free and replies refund credits. Connection requests are free and leave you with lasting first-degree connections, a long-term asset InMail never creates.

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. Replace the answer body of the "Can I send InMail for free?" Faq at line 149 with: "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." A meaningful share of prospects have it enabled, so always check before spending a credit. You can also earn credits back when InMail recipients reply within 90 days.
