Business: [BRAND NAME]
Platform: [WHAT WEBSITE / APP / PRODUCT DO USERS INTERACT WITH]
Key user behaviors we can track: [LIST EVENTS — E.G., PAGE VIEW, SIGN UP, TRIAL START, FEATURE USED, PURCHASE, INACTIVITY]
Business model: [SAAS / E-COMMERCE / APP / MARKETPLACE]
Goal: [ACTIVATION / CONVERSION / RETENTION / EXPANSION]

Build a behavioral trigger email library:
1. Onboarding triggers: 5-7 behavioral emails based on what users do (or don't do) in week 1
2. Feature adoption triggers: emails that fire when users discover (or ignore) key features
3. Upgrade intent signals: behavioral patterns that indicate readiness to buy/upgrade — and the email to send
4. Churn risk triggers: early warning behaviors and automated intervention emails
5. Milestone celebration triggers: emails for meaningful user achievements
6. Inactivity triggers: a graduated sequence for users who go quiet
7. Purchase behavior triggers: cross-sell, upsell, and replenishment based on what they bought
8. Abandonment triggers: cart, checkout, trial, onboarding step abandonment
9. Personalization rules: how to use behavioral data to personalize non-triggered campaigns
10. Suppression logic: when NOT to send an email to avoid overwhelming users
