Comparison
SuperMailOS vs Google Workspace
Google Workspace is the default for a reason: Gmail's inbox, the whole office suite, and “nobody ever got fired for buying Google.” This page is not here to pretend that gravity doesn't exist. It's here to show what you're paying for and what an email-first alternative actually trades.
| Google Workspace | SuperMailOS | |
|---|---|---|
| Pricing model | Per user per month, tiered by storage + suite features | Per mailbox: Pro $4/mo ($3 annual, 3 domains), Business $6/mo ($5 annual, unlimited domains) |
| Aliases | Aliases/groups exist, but every address a human reads needs a licensed user behind it | Unlimited, free, every domain — aliases deliver into real inboxes |
| Suite | Docs, Drive, Meet, Calendar — the full stack | Email-first: inbox, aliases, IMAP/SMTP, deliverability |
| Multiple domains | Supported as secondary/alias domains on the workspace | The core design: every domain, one inbox, independently authenticated |
| Deliverability | Excellent infrastructure; DKIM setup and DMARC reports are DIY | Managed end to end with a live dashboard |
Where Google Workspace wins
- The suite is real. Docs, Drive, Meet, Calendar share one identity. If your team lives there, recreating that stack costs more than the subscription saves.
- Gmail's inbox. Fifteen years of filtering, search, and spam-model polish — and everyone already knows it.
- Deliverability by default. Google's sending reputation is about as good as shared infrastructure gets.
Where SuperMailOS wins
- Alias economics. On Workspace, a functional support@ a human reads means a licensed user. Here, unlimited aliases are free — you pay for people.
- Multi-domain as the product. Agencies and multi-product founders get every domain in one inbox with per-domain authentication and deliverability visibility — not secondary-domain bookkeeping.
- Price per human. For email-only needs, $4 a mailbox beats paying for suites nobody on that seat will open.
- Deliverability operated. SPF/DKIM/DMARC from the mail server's own zone, DMARC parsing, warmup and IP reputation managed, with a dashboard instead of admin-console archaeology.
Which one fits you
Team embedded in Docs and Meet: stay on Workspace, honestly. Email- heavy operation — many domains, many role addresses, deliverability that matters to revenue: that's SuperMailOS territory. The deeper comparison ( including Microsoft 365, Zoho, Fastmail, self-hosting ) is in this guide.
FAQ
Can I keep using Gmail's interface?
Yes, via IMAP — SuperMailOS provides standard IMAP/SMTP access, so Gmail, Apple Mail, Outlook, or any client works. Your deliverability runs on our managed infrastructure regardless of the interface.
Will moving hurt my deliverability?
Authentication is provisioned from the mail server's zone during setup, and warmup is part of the managed service — the common self-migrated mistakes are handled for you.
Do you replace Docs/Drive/Meet?
No. Plenty of customers run SuperMailOS for mail and free tools for the rest — that math usually favors us once aliases multiply.
