    Send mail

    One API in front of every provider.

    Test against the sandbox, then connect AWS SES, Postmark, Resend, SendGrid, Mailgun, or your webhoster's SMTP when you ship. Your app code stays the same.

    01

    REST shape that's already familiar

    POST /v1/messages mirrors the SendGrid/Postmark/SES REST envelope. Swap a base URL and a bearer, keep your code.

    02

    10+ destination types built in

    SES, Postmark, Resend, SendGrid, Mailgun, generic SMTP, plus presets for European webhosters like cyon, Hostpoint, Infomaniak, IONOS, OVH, Mittwald.

    03

    Routing rules + failover

    Route by from-domain, environment, or any header field. Set a failover chain; if the primary times out, the next destination picks up automatically.

    04

    Idempotency keys

    Pass an idempotency_key on retry-prone callers. Duplicate POSTs return the original trace ID instead of producing a second send.
