Good for
- People leaving free, ad-funded email for a paid private service
- Using your own domain for personal or family addresses
- Small businesses that want email without a full office suite
Worth knowing
- There is no free plan. After the 30-day trial every account is paid, and Fastmail does not refund unused subscription time.
- The Basic business plan has 6 GB per user and leaves out custom domains, Scheduled Send, Snooze and third-party mail apps.
- Storage beyond the plan allowance is a paid add-on, up to 300 GB per user.
- Listed prices are tax-exclusive.
Key features
- Custom domains and extra addresses
- Use domains you own for your addresses, buy one through Fastmail, or pick one of its free domains. Fastmail says each account can create hundreds of additional addresses.
- Masked Email
- Creates stand-in addresses so that sign-up forms and logins never see your real one. A Masked Email API lets password managers create them too.
- Offline apps on every platform
- Apps for Windows, macOS, Linux, iOS and Android, plus a browser app. Offline, you can read, draft and search mail and manage calendars and contacts.
- Snooze, Scheduled Send and pinning
- Snooze messages until they are needed, schedule sends for later, pin important messages to the top of the inbox and mute threads you do not want to follow.
- Calendar and contacts
- A built-in calendar with shared calendars and event invitations that can also display Google and iCloud calendars, and a contact list with VIP-only notifications.
- Open protocols and import
- Mail is reachable over JMAP, IMAP and POP, contacts over CardDAV and calendars over CalDAV. An import tool moves mail, calendars and contacts from another provider.
