Now onboarding · a small number of teams

Email your customers actually receive.

Transactional email on your own domain and your own sending reputation. One API, a suppression list that is yours alone, and every delivery event kept where you can read it.

You're warned at 80% of your allowance, and transactional mail keeps sending past it.

Why it lands

Deliverability is the whole product.

Everything below exists to keep your domain trusted, and to let you prove it did.

Per-account suppression

Someone else's bounce is never your problem

Suppression is scoped to your account, not pooled across the platform. A hard bounce for another sender never quietly blocks that address for you.

Domain ownership

Two proofs before a message can leave

A domain sends once its DKIM records verify and a challenge shows this account controls it.

Idempotent by key

Retry a send without sending twice. The key is yours and we honour it.

Event trail

Every event, kept and readable

Accepted, delivered, bounced, complained. Each carries its timestamp and its reason, per recipient, for as long as you need it.
