Event-driven lifecycle flows
Lifecycle automation starts with trustworthy events, not pretty canvases. Define triggers, idempotent enrollments, exit criteria, and measurement before you draw branches.
Lesson objectives
- Map a welcome-to-activation flow from product events
- Prevent double sends with idempotent enrollment keys
- Choose delay and branch logic that matches user state
Events first, canvas second
If signed_up, project_created, and subscription_canceled are messy, no visual builder will save you. Invest in a clean event taxonomy and a contact profile that automations can read without brittle joins.
A durable graph shape
- Trigger node with idempotency key
- Delay or wait-until-condition nodes
- Send nodes pinned to email versions
- Branch on events or attributes
- Exit on conversion or suppression
Worked exercise: Specify one activation flow
- Write the entry event, quiet hours, and exit events.
- List three message steps with success metrics.
- Identify the ESP or automation API you would publish to.
End-of-lesson checklist
- Entry and exit events documented
- Timezone and quiet hours defined
- Holdout or experiment plan noted
- Failure path for missing profile fields
