.mdSet up SuperMailOS, end to end
Short, accurate guides to the whole path: connect a mail app, point your domain, understand what we do for deliverability, lock down your account, and migrate your existing mail. We run the mail server, so most of the hard parts are already handled.
Connect a mail app (IMAP/SMTP)
Add your mailbox to Apple Mail, Outlook or Thunderbird using mail.supermailos.com, IMAP 993 and SMTP 465, with an app password.
ReadSet up your domain's DNS
Point your domain at the mail server: MX, SPF, DKIM and DMARC — one click on supported providers, copy-paste anywhere else.
ReadDeliverability & inbox placement
What we handle for you — DKIM signing, DMARC reporting, warm-up, IP reputation — and the few habits that keep you landing in the inbox.
ReadSecurity: 2FA & sessions
Turn on two-factor authentication, manage active sessions, and use per-app passwords for mail clients.
ReadMigrate your existing mail
Move from your current provider without downtime: create mailboxes, copy mail over IMAP, then cut DNS across when you're ready.
ReadPrefer to check your domain first?
The free email deliverability checker looks up your SPF, DKIM, DMARC, MX and MTA-STS records and explains, in plain English, what to fix.
