Comparisons
SuperMailOS vs the usual suspects
Every comparison below says where the other provider genuinely wins. Pick the tool that fits — if that's not us, these pages should still be the most honest thing you read today.
vs Zoho Mail
Zoho Mail alternative
Zoho is a full suite at a fair price. We compare on aliases, multi-domain handling, and who manages deliverability.
vs Google Workspace
Google Workspace alternative
The suite gravity is real. We compare on price per mailbox, alias costs, and what you give up when you leave.
vs Fastmail
Fastmail alternative
Fastmail is a beloved independent. We compare on custom-domain limits, alias pricing, and managed DMARC.
vs Microsoft 365
Microsoft 365 alternative
365 bundles Office. We compare on email-only costs, per-domain setup, and small-team simplicity.
vs Proton Mail
Proton Mail alternative
Proton encrypts everything. We compare on privacy models, custom domains, and deliverability tooling.
vs Migadu
Migadu alternative
Migadu prices by volume, not addresses. We compare the two models honestly — and where each wins.
vs Purelymail
Purelymail alternative
Purelymail is famously cheap. We compare on what managed deliverability actually buys you.
vs self-hosting
Self-hosted email, honestly
We run the mail server so you don't have to. What self-hosting really costs in time, and when it's still the right call.
