About

SuperMailOS is managed business email on your own domain for small teams. You bring your domain; SuperMailOS runs the mail server and handles deliverability — SPF, DKIM, DMARC, IP reputation, and warmup — so your email lands in the inbox, not the spam folder. Setup takes minutes: verify your domain with one-click DNS on Cloudflare, DigitalOcean, and other providers (or guided copy-paste on any registrar), invite your team, and start sending. Every person gets a real mailbox; aliases like hello@ and support@ are unlimited and free. Webmail is as simple as Gmail — threads, instant search, keyboard shortcuts, labels, dark mode — plus IMAP and SMTP for any mail app, and a live deliverability dashboard showing your mail landing. Flat pricing per mailbox: Pro $3/mailbox/month annually (10 GB, 3 domains), Business $5 (30 GB, unlimited domains), custom at 50+. 14-day free trial, no credit card.

Pros & Cons from Real Users

Pros

  • Don't know, can't start using this because: it was not possible to use it offline and I don't want/need another account next to my mail accounts to manage mails!

Cons

  • I was not able to use this client as offered, as a free mail client, because I don't need the options you have to pay for. (that's ok, if you want this special options, pay for it) And I don't know why I need a special account next to my mail accounts to manage my mails! Here is the big fail in the concept, all the features you can enable thru mail accounts... so I wonder and start thinking why they want this on their own system? I'm not a paranoid, but if you know many about privacy then you know this is not you client for managing mails!
