The journeys that pay for the channel
Sandbox parity
Test rejection, bounce and complaint paths without touching a real recipient.
Idempotency by default
Retries are safe; duplicate keys return the original message id.
Typed errors
Every error code links to the doc page for that code and the recommended handling.
Self-serve keys
Create, scope and rotate keys yourself, with per-key rate limits and audit history.
