Comparisons
SuperMailOS vs the usual suspects
Every comparison below says where the other tool genuinely wins. SuperMailOS is hosted business email — we run the mail server, the sending IPs and the deliverability work — so pick whatever fits. If that isn’t us, these should still be the most honest pages you read today.
vs Mailflare
Hosted email vs a self-hosted Cloudflare app
Mailflare is an open-source inbox you self-host on your own Cloudflare account. We compare fully hosted mailboxes, IMAP/SMTP and managed deliverability with self-hosting it yourself.
vs Zoho Mail
Email-first vs a low-cost suite
Zoho is a cheap all-in-one suite where you maintain your own authentication. We compare on free aliases, multi-domain handling and who operates deliverability.
vs Fastmail
Multi-domain email with DMARC visibility
Fastmail is a polished per-user host. We compare on multi-domain economics, DMARC reporting and one-click DNS — and call the IMAP/SMTP and 2FA ties honestly.
vs Google Workspace
Per-mailbox pricing vs per-user seats
The suite gravity is real. We compare on alias economics, price per person and managed deliverability — including where Workspace is simply the right call.
