Posting is one request

Drop it in the box. We'll do the rest.

A plain REST API with no SDK to install. If your till, website or app can make an HTTP request, it can send email. Retries never double-send thanks to idempotency keys.

Everything a busy shop needs. First class, every time.

Webhooks for delivered, bounced and opened, signed with HMAC and retried for up to 17 hours.
