Features
Everything managed email should include.
SuperMailOS is hosted business email: we run the mail server, the sending IPs and the deliverability work. The parts other tools leave to you are simply included — on every plan, on every domain you connect.
Deliverability
We run the mail server, so reputation is our job
DKIM on every message, SPF and DMARC from the server's own zone, a DMARC report dashboard, new-domain warm-up and sending-IP reputation watched day and night.

Domains & aliases
Add a domain in minutes, unlimited free aliases
One-click DNS across six hosts (copy-paste anywhere else), records taken from the real server zone and verified live, and unlimited free aliases on every domain.

IMAP & SMTP
Your mail app still works
Standard IMAP and SMTP over SSL on every plan, with per-client app passwords, so Apple Mail, Outlook, Thunderbird and mobile just work. The webmail is optional.

Security
Locked down by default
TOTP two-factor, session visibility, revocable app passwords and real per-message DMARC/DKIM authentication badges — we never claim a pass we can't back.
