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 Response Rates by Industry (2025)
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.
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
