The reply rate data
| Channel | Cold reply rate | Warm-signal reply rate | Daily volume cap |
|---|---|---|---|
| LinkedIn DM | 12-15% | 25-40% | ~16/day (invitations) |
| Cold email | 2-5% | 6-12% | 200-500/day with proper warmup |
| Multi-channel (LI + email) | 15-20% | 32-48% | Sum of both |
When LinkedIn wins
- Targeted, lower-volume outbound (5-50 prospects/day)
- Warm-signal sources (post commenters, event attendees)
- Founder-led sales (peer-to-peer voice)
- High-LTV deals where each touch matters
When cold email wins
- High-volume top-of-funnel (100+ prospects/day)
- You already have verified work emails
- Markets with low LinkedIn adoption (some emerging markets)
- Audiences who don't check LinkedIn daily
The multi-channel approach
- Day 0: LinkedIn connection request with warm-signal reference
- Day 2: Email if no LinkedIn acceptance after 48 hours
- Day 5: LinkedIn DM if connection accepted
- Day 8: Email follow-up
- Day 12: LinkedIn soft close
Multi-channel sequences double total reply rates compared to single-channel.
