Agencies send on behalf of many client domains and must isolate reputation per client.
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.
Implementation plan for marketing agencies#
- 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.
Priorities specific to marketing agencies#
Agencies send on behalf of many client domains and must isolate reputation per client. Weight your effort toward the steps above that address this constraint first, and measure with metrics that match how marketing agencies generate value from email.
Common mistakes#
- Using email address as the only identifier when users change it.
- No retry logic for failed webhook deliveries.
Frequently asked questions#
Webhook vs API polling for email automation?
Webhooks are real-time and cheaper. Use polling only as a fallback reconciliation.
