Opt-in form placement (do ALL):
Double opt-in flow:
Signup → Confirmation email (immediate) → "Click to confirm" → Welcome email (instant) → Sequence beginsDouble opt-in reduces list size 20-30% but improves deliverability and engagement significantly. Use it.
Tier 1 — Behavioral segments (highest value):
yamlsegments: super_engaged: criteria: "Opened 3+ emails in last 14 days AND clicked 1+" treatment: "Early access, exclusive offers, higher send frequency" engaged: criteria: "Opened 1+ email in last 30 days" treatment: "Standard campaigns + promotional" warm: criteria: "Opened 1+ email in 31-60 days, no recent clicks" treatment: "Re-engagement content, best-of, reduce frequency" cold: criteria: "No opens in 60-90 days" treatment: "Win-back sequence, then sunset" dead: criteria: "No opens in 90+ days despite win-back" treatment: "Remove from list — they're hurting deliverability" new_subscriber: criteria: "Joined in last 14 days" treatment: "Welcome sequence only, no promotional" customer: criteria: "Made a purchase" treatment: "Post-purchase flow, upsell, loyalty" high_value_customer: criteria: "Purchase >$500 OR 3+ purchases" treatment: "VIP offers, early access, personal touch"
Tier 2 — Interest-based segments:
Tier 3 — Lifecycle segments:
| Action | Frequency | How | |--------|-----------|-----| | Remove hard bounces | After every send | Automatic in most ESPs | | Remove spam complaints | After every send | Automatic | | Clean soft bounces | Monthly | Remove after 3 consecutive soft bounces | | Re-engage cold subscribers | Every 60 days | 3-email win-back sequence | | Sunset unengaged | Every 90 days | Remove anyone who didn't engage with win-back | | Validate list | Quarterly | Run through NeverBounce/ZeroBounce | | Audit segments | Monthly | Check segment sizes, merge overlaps |
