Does Fastmail work with Outlook, Apple Mail, and Thunderbird?

Yes — full IMAP support means any standard client works, and calendars and contacts sync over CalDAV and CardDAV. The native apps and webmail are good enough that many users stop needing a separate client.

How does migration from Gmail work?

Fastmail's built-in importer pulls mail, contacts, and calendars from Google directly over IMAP. Do the import first, then switch your domain's MX records — in that order, downtime is effectively zero.

Its business model is subscriptions, not advertising, and it doesn't scan mail to profile you. Note that it isn't end-to-end encrypted at rest the way Proton Mail is — if E2E encryption is a hard requirement, Proton is the better-fit choice.

Fastmail Review

Fastmail's pitch is that email deserves to be someone's whole product, not a loss-leader for an advertising business or an office suite. At $3/user/mo it charges for that focus directly. After using it against the suite defaults, here's where we think it fits. Prices were verified in July 2026.

Summary verdict

Verdict

Fastmail is the best per-seat email host for individuals and small teams who want polish without a suite: $3/user/mo on the Basic plan (billed annually), no intro-discount-then-renewal-jump, first-class custom-domain support, and the fastest webmail we've used. It is deliberately not a Google Workspace replacement — there are no shared docs or meetings — and it's priced accordingly.

What Fastmail does well

Speed is the brand and it's earned — the webmail and mobile apps are noticeably quicker than Gmail or Outlook, built on the JMAP protocol Fastmail itself helped standardize alongside full IMAP, CalDAV, and CardDAV support.

Masked email is the quietly great feature: generate a unique address per signup, and when one starts getting spam you know exactly who leaked it and can kill it without touching your real address. Custom domains are supported properly on every paid plan, with straightforward DNS guidance including SPF, DKIM, and DMARC.

The pricing is adult: $3/user/mo Basic billed annually ($4 billed monthly), cheaper on 24- or 36-month terms, and no first-year promo games — the renewal price is the sticker price, which makes multi-year budgeting boring in the best way.

Where it falls short

It's email, calendars, and contacts — full stop. No documents, no shared drives, no meetings. Teams that need those pair Fastmail with other tools or should honestly just buy Google Workspace at $7/user/mo.

Per-seat pricing has a floor: at five-plus mailboxes that don't each belong to a daily human user, flat-fee hosts like MXroute ($59/yr, unlimited mailboxes) become dramatically cheaper for role accounts and secondary domains.

Storage on Basic is modest; heavy archivers will want the higher tier. Check current allowances against your mailbox size before migrating.

Best fit for

+Solo founders and small teams on custom domains
+Anyone de-Googling without giving up a polished client
+Privacy-conscious users who prefer paying to being profiled

Consider another option if

−Your team needs shared documents, drives, or video calls
−You want the cheapest possible mailbox — flat-fee hosts undercut per-seat pricing
−You require enterprise compliance tooling and SSO

Questions readers ask

FAQ

If you're on your own domain, the comparison isn't with free Gmail — custom-domain Google means Workspace at $7/user/mo. Against that, Fastmail at $3/user/mo is less than half the price for arguably better email. Against a free @gmail.com address, you're paying $36/yr for your own domain, privacy, and support.
