What email automation triggers are#
Triggers are events (form submission, purchase, page view, CRM stage change) that start or advance an automation. Webhooks and APIs carry those events between systems.
Why it matters#
The quality of automation is bounded by the quality of the events feeding it. Reliable triggers make journeys feel personal.

- List the events your product or store already emits.
- Send them to your ESP via webhook or native integration with a stable contact identifier.
- Deduplicate and validate payloads before they enter automations.
- Monitor for silent failures: a broken webhook stops journeys without errors.
