Audience
Small and medium businesses, startups, agencies, and freelancers who want professional email on their own domain without running a mail server or managing DNS and deliverability themselves.
About SuperMailOS
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.
