How do suppressions work with triggers?

Suppressions prevent automation triggers from firing for specific recipients, ensuring excluded contacts do not receive messages:

Global suppressions: Unsubscribes, hard bounces, and spam complainers should never trigger any marketing automation.

Flow-specific suppressions: Contacts already in certain flows, recent purchasers, or VIP customers who receive different treatment.

Temporary suppressions: Recipients in a cooling-off period after recent contact or specific interactions.

Segment-based suppressions: Exclude entire segments from specific automations (e.g., employees, test accounts).

Implementation requires suppression checks at the moment of triggering, not just at send time. The automation should not start if the recipient is suppressed.

Suppressions are the guardrails of automation. They prevent the system from doing what it technically could but should not.
