Can I migrate from Gmail or other providers to Fastmail?

Yes. Fastmail is designed to be a destination you can move to from Gmail, Google Workspace, iCloud, or another provider, and the site specifically calls out a Gmail transfer tool. The practical answer is that migration is supported for mail, calendar, and contacts, but how much manual work you face depends on what you're bringing over and whether you're moving a personal account or a whole business.

What Fastmail says about switching

Fastmail positions itself directly as an alternative to Gmail and iCloud for email, calendars, and contacts. Its homepage quotes a user who says they "migrated from Google Workspace to Fastmail and would never go back," and another reviewer notes Fastmail "has a Gmail transfer tool."

That matters for two reasons:

• It's an explicit use case, not an afterthought. Migration is part of how Fastmail markets itself, so you're not trying to force a tool into a job it wasn't built for.
• The Gmail path is the best-documented one. If you're coming from Gmail or Google Workspace, you're on the route Fastmail most clearly supports.

What you can bring over

Based on Fastmail's own feature descriptions, migration covers the three things that usually matter most:

The calendar point is worth pausing on. Fastmail lets you add your Google or iCloud calendars into its own calendar view. That means you don't necessarily have to abandon an existing calendar immediately — you can keep it visible while you decide how fully to commit.

How the migration generally works

Fastmail's site doesn't publish a step-by-step migration walkthrough in the material available here, so treat the following as the general shape of an IMAP-style move rather than a quoted procedure:

1. Create your Fastmail account. The site offers a free 30-day trial for business with "no obligation, no credit card required," so you can test the move before committing.
2. Choose your data residency. Fastmail asks you to pick a primary data residency: EU or USA. This is a decision to make early, since it affects where your data lives.
3. Import mail. Use the Gmail transfer tool (or standard IMAP import) to pull messages across. Expect large mailboxes to take time.
4. Bring over calendar and contacts. Either import them or connect your existing Google/iCloud calendar so it appears alongside Fastmail's.
5. Verify. Check that folders/labels, sent mail, and recurring calendar events arrived intact — these are the usual places imports go sideways.

Expected result: your mail, calendar, and contacts visible inside Fastmail, with your old provider still available as a fallback until you're confident.

Common snags to plan for

• Labels vs. folders. Gmail's label system doesn't map one-to-one onto folder-based mail. Some reorganization is normal.
• Large attachments and long histories. These slow imports down; budget time rather than expecting an instant switch.
• Shared or delegated calendars. If others depend on your calendar, coordinate the change so invitations don't get lost.
• Keeping the old account alive. Don't delete your Gmail or Workspace account until you've confirmed everything arrived. Fastmail's own reviewer praise centers on people who moved, not on people who burned the bridge on day one.

Is it worth switching?

The case Fastmail makes is privacy and independence: as a paid service, it says it has "no split loyalties, no mining of your personal data, no sharing it with third parties, and no ads, ever." If that's your reason for leaving Gmail, the migration tooling exists to make the move practical.

If you only want a second inbox and don't care about the privacy angle, the effort of a full migration may not be worth it — you could simply add your existing calendars and test the free trial first. The 30-day business trial with no credit card required is the lowest-risk way to find out whether Fastmail fits before you commit your whole mailbox to it.
