SMTP, DKIM signing, and a scoped REST API for every domain you own — self-hosted, not billed per message.
Features
The three pieces that make self-hosting worth it.
Point any domain here — DNS verification is automatic.
Every message is DKIM-signed and delivered by your own SMTP server.
Per-domain, per-account permissions — nothing more than a key needs.
DNS verification, DKIM signing, and SMTP are ready as soon as you connect a domain.
