Atrix Mail documentation
Everything you need to host mail on your own domain, send programmatically, and plug Atrix Mail into your stack.
Atrix Mail is three things on one platform: mailbox hosting for any domain you own, a Resend-style sending API for product email, and an AI-native webmail. These docs cover the first two; the webmail explains itself.
