The 4 email sequences every business needs in 2026 are: welcome (5 emails), nurture (7 emails), sales (4 emails), and re-engagement (3 emails). Each has a proven open/click/reply structure below.
An email sequence is a series of pre-written, auto-sent emails triggered by a user action (signup, purchase, inactivity). Unlike a one-off blast, sequences carry narrative and build trust.
| Metric | One-off Blast | Triggered Sequence |
|---|---|---|
| Avg open rate | 17% | 38% |
| Avg click rate | 1.4% | 6.8% |
| Revenue per email | \$0.08 | \$0.52 |
| Unsubscribe rate | 0.9% | 0.3% |
