Comparisons
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.
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.
/compare/mailflare
vs Zoho Mail→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.
/compare/zoho
vs Fastmail→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.
/compare/fastmail
vs Google Workspace→The suite gravity is real. We compare on alias economics, price per person and managed deliverability — including where Workspace is simply the right call.
/compare/google-workspace
vs Migadu→Migadu prices a whole account by daily volume, with unlimited addresses and domains. We compare the two models with Migadu's real tiers, and say where each wins.
