SuperMailOS

Professional email on your own domain — [email protected] — without running a mail server. You bring a domain. We generate every DNS record from the mail server's own zone, verify it live while you watch, run the MTA, sign every message with DKIM, and manage SPF, DMARC and IP reputation. There's a dashboard showing your mail is actually landing. Then it's just email: threads, instant search, keyboard shortcuts, labels, signatures, dark mode. IMAP/SMTP too. From $3/mailbox/mo. Aliases free.
