Endpoints
Send a test webhook
Sends a sample email.received event to the endpoint. The request includes SSRF protection (private IP rejection and DNS pinning). Rate limited to 4 per minute and 30 per hour (non-exempt). Successful deliveries and verified-domain endpoints are exempt from the rate limit.

Headers
Idempotency-Keystring
Optional client-supplied idempotency key. Retrying a request with the same key returns the original result instead of performing the action a second time; if omitted the server derives one from the canonical payload hash. Safe to retry network failures without duplicating side effects.
