LinkedIn InMail vs Connection Request: What Actually Gets Replies
Should you pay for InMail or stick with free connection requests? We analyzed response rate data from 2025 studies to give you a clear answer.
TL;DR — The Quick Answer
Connection requests win for most use cases. They're free, have higher response rates (25-35% vs 10-25%), and build lasting relationships. InMails cost ~$10 each and should be reserved for high-value targets you can't reach otherwise.
Best strategy: Start with connection requests. Use InMail only for prospects who declined your request or for C-suite executives where a direct approach makes sense.

InMail
Average InMail response rate. Top performers hit 35-40%, poor campaigns get under 10%
Key Insight from 2025 Data
LinkedIn DMs now perform 101% better than cold emails (which dropped to 5.1% response rate in 2025). But connection requests outperform InMails because they establish a relationship first.
Head-to-Head Comparison
| Metric | InMail | Connection | Winner |
|---|---|---|---|
| Average Response Rate | 10-25% | 25-35% | Connection |
| Cost Per Message | ~$10 each | Free | Connection |
| Monthly Limit | 50 (Sales Nav) | ~100/week | Connection |
| Reach Non-Connections | Yes | Limited | InMail |
| C-Suite Access | Better | Often ignored | InMail |
| Long-Term Value | One message | Ongoing relationship | Connection |
Connection requests beat InMail on response rate (25-35% vs 10-25%), cost (free vs ~$10 each), and volume (~100/week vs 50/month). InMail only wins for reaching C-suite executives who ignore connection requests.

InMail Response Rates by Industry (2025)
Legal & Professional Services10.42%
Healthcare9.25%
Retail & Consumer Goods9.17%
Software & SaaS4.77%
Why SaaS Has the Lowest Rate
Software & SaaS professionals receive the most LinkedIn outreach, leading to message fatigue. If you're targeting SaaS, personalization isn't optional — it's survival. Consider connection requests with engagement first.
InMail response rates vary by industry: Legal & Professional Services (10.42%), Healthcare (9.25%), Retail (9.17%), and Software/SaaS (4.77%). SaaS has the lowest rate due to message fatigue from high outreach volume.
Maximizing Connection Request Success
Target 2nd-Degree Connections
2nd-degree connections have significantly higher acceptance rates. Mutual connections provide social proof and make your request feel less cold.
Filter for Active Users
People who posted in the last 30 days have 2x higher acceptance rates (33% vs 12% in one study). They're active and engaged.
Keep Notes Short
Messages under 400 characters get 22% better response rates. Surprisingly, connection requests with and without notes have similar acceptance rates (~26%). What matters more is targeting and timing.
Optimal Timing
Tuesday has the highest reply rate (6.90%), followed by Monday (6.85%). Weekends drop to 6.40%. Send during business hours in recipient's timezone — 9-11am or 2-4pm.
When to Use Each Approach
Use Connection Requests When:
- ✓Building a long-term network
- ✓Targeting mid-level professionals
- ✓You have mutual connections
- ✓You want to engage with their content first
- ✓You're on a budget
Use InMail When:
- ✓Targeting C-suite executives
- ✓They declined your connection request
- ✓You have a time-sensitive offer
- ✓The prospect is a 3rd-degree+ connection
- ✓You have high-value, highly personalized message
Use connection requests for most outreach — higher acceptance, free, builds relationships. Use InMail only for C-suite executives who ignore requests, prospects who declined your connection, or 3rd-degree+ connections with highly personalized, high-value messages.
The Optimal Combined Strategy
Engage First
Like and comment on their posts before sending anything. Get on their radar.
Send Connection Request
Short, personalized note referencing their content or mutual connections.
Follow Up via DM
Once connected, send your actual outreach message. Free and unlimited.
InMail as Last Resort
If they ignore/decline your connection request and they're a high-priority prospect, try InMail.
Why This Works
Connection requests build real relationships — your content appears in their feed, and you can message them anytime for free. InMails are one-and-done transactions at ~$10 each. The math favors connections for 90% of prospects.
