In their own words

Fastmail Email

Fastmail Email provides email, calendars, contacts, and file storage for individuals, families, and businesses. Mail tools include search, pinning, snooze, scheduled sending, offline support, and private memos on messages. Fastmail says its paid service has no ads, personal-data mining, or third-party sharing. It says customer data is encrypted in transit and at rest, supports TLS 1.3 and Perfect Forward Secrecy, and offers two-step verification and passkeys. Customers can choose the EU or US as their primary data residency. Fastmail offers apps for Windows, macOS, Linux, iOS, and Android, plus a browser app. Access protocols include JMAP, IMAP, POP, SMTP, CardDAV, CalDAV, and WebDAV; OAuth is documented for third-party clients. Fastmail does not provide end-to-end encryption in its own apps, though PGP or S/MIME can be used through supported third-party apps. Plans range from Basic at $4 a month to Family at $14 a month, with different storage and account allowances. The service is paid, has no free plan, and offers a 30-day trial. Every plan includes 24/7 expert support from real people.
