Comparison
SuperMailOS vs Migadu
Migadu is the indie darling of email hosting, with a pricing model almost nobody else dares: pay by volume, get unlimited mailboxes and domains. It's a genuinely smart model — and comparing it honestly with SuperMailOS's per-mailbox model is a lesson in what you actually pay for.
| Migadu | SuperMailOS | |
|---|---|---|
| Pricing model | By daily sending volume tier; unlimited addresses and domains within the tier | Per mailbox: Pro $4/mo ($3 annual, 3 domains), Business $6/mo ($5 annual, unlimited domains) |
| Addresses | Unlimited — the headline feature | Unlimited aliases free; human mailboxes are the paid unit |
| Deliverability | Self-serve DNS; you manage your setup and reputation | Managed: server-generated records, warmup, DMARC parsing, dashboard |
| Interface | Webmail + standard protocols; bring your own client culture | Gmail-like inbox ( threads, search, shortcuts ) + IMAP/SMTP |
| Best at | Many addresses, low volume, DIY-comfortable operators | Teams that want email operated for them |
Where Migadu wins
- Address abundance. If you want 200 addresses and 15 domains tomorrow, one volume tier covers it — nobody else matches that shape.
- Price at low volume. A low-sending indie operator pays very little for enormous address freedom.
- Culture. Small, principled, well-liked — the “email for people who like email” option.
Where SuperMailOS wins
- Predictable cost per person. Volume tiers bite when a campaign day spikes sends; per-mailbox pricing doesn't meter your email bill against your marketing.
- Deliverability is a service. Records generated from the mail server's zone, DMARC reports parsed, warmup and IP reputation managed, per-domain visibility — versus running your own setup discipline.
- A real product inbox. Threaded, searchable, keyboard-driven webmail your whole team can live in — plus IMAP/SMTP for the client loyalists.
Which one fits you
Solo operator who enjoys email mechanics and sends modestly: Migadu is a great deal. A team, or anyone who'd rather never think about DNS records and reputation curves: SuperMailOS pricing buys the whole job done.
FAQ
Is unlimited aliases the same as Migadu's unlimited addresses?
Functionally similar for role addresses — the difference is the paid unit: Migadu meters volume, we meter human mailboxes. Aliases are free and unlimited here on every plan.
What happens if I exceed my volume on Migadu vs seats on SuperMailOS?
Overages are a Migadu question ( tier upgrades ); here you add a mailbox when you add a person. No sending meter on your invoice.
Can I migrate from Migadu?
Yes — IMAP migration, DNS from the generated zone, typically under five minutes per domain to switch over.
