The email channel, end to end.
Deliverability, versioned templates, inbound parsing, signed webhooks, and typed SDKs, all behind one send call.
Bounces and complaints feed suppression automatically.
Your reputation stays clean without you watching it. You send from your own domains with SPF, DKIM, and DMARC managed for you, and every bounce or complaint feeds the suppression list on its own.
Pass data by name. The rendered message goes out server-side.
Reference a template by name, pass the data, and the version you pinned is the version that sends. Transactional and product email share the same templates, rendered on our side. No separate template service to wire up.
Replies parse and thread back into your app.
A reply is something your code handles, not something a human forwards. Inbound email arrives parsed and threaded as an event in your app, never dropped in a side mailbox you have to poll.
Thanks, got the shipping update. One question…
Every send comes back as a signed event you can verify.
Every delivery, bounce, and complaint comes back as an HMAC-signed webhook you can verify with a typed verifier in the SDK. We retry with backoff until your endpoint acknowledges, so you never miss an event.
Same key on retry returns the same send.
A flaky network never turns into a duplicate email. Reuse an idempotency key across retries and you get the original message id back, through end-to-end types in the SDK or the same JSON contract over REST.
- Idempotency keys, so a retry returns the original send, not a second email
- REST API with an OpenAPI 3 spec, so you generate a client in any language
- Typed webhook verifier in the SDK, no shared-secret guesswork
