Who each one suits
Fastmail

- Using your own domain for personal or family addresses
- Small businesses that want email without a full office suite
StartMail

Worth knowing
Fastmail
- 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.
StartMail
- There is no free plan, and the 7-day trial asks for a credit card or PayPal account at sign-up.
- The only app is for Android; the iOS app is listed as coming soon. Elsewhere it runs in the browser or in other mail apps over IMAP.
- Personal accounts are limited to one custom domain; unlimited domains and shared aliases need the Business plan.
- The feature list covers email and contacts only and does not mention a calendar or file storage.
Key features
Fastmail
- 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.
StartMail
- Unlimited aliases
- Extra addresses can be created and deleted at any time, on the StartMail domain or your own, and one-click burner aliases disappear on their own after an hour.
- PGP encryption
- One click encrypts a message with PGP or adds a PGP signature, and an IMAP mail client can be set up for end-to-end encryption with OpenPGP.
- Password-protected email
- Encrypted messages can be sent to people who do not use encryption: the recipient reads and answers them with a password you set.
- Tracking and phishing protection
- External images are hidden by default to block tracking pixels, a warning shows the full address before an external link opens, and your IP address is kept out of sent mail.
- Custom domains and group subscriptions
- Personal accounts can use one custom domain and Business accounts any number. Extra accounts for family or team members are 25% off, and Business groups can share aliases.
- IMAP access and migration
- Full IMAP and SMTP access for Thunderbird, Outlook, Apple Mail and similar apps, plus a migration tool that imports email and contacts from other providers.
