How to ensure automations update suppression data in real-time?

Real-time suppression prevents sending to contacts who just opted out:

Event-driven architecture: Suppression events trigger immediate updates. No waiting for batch sync. Automation checks current suppression state.

Webhook integration: ESP sends webhook on unsubscribe. Connected systems receive instant notification. Suppression applies before next send.

Synchronous checks: Automation queries suppression status before each send. Real-time verification, not cached status. Slight latency is acceptable trade for accuracy.

Cross-system sync: Unsubscribe in any system propagates to all. Central suppression list referenced by all senders. No system operates with stale suppression data.

Verification testing: Test unsubscribe and verify no further sends. Monitor for send-after-unsubscribe incidents. Alert immediately on failures.

Real-time means before the next send. Any delay risks compliance violations.
