Who it's for

Individuals and businesses who want a paid, privacy-focused alternative to free webmail providers like Gmail or Outlook, and who want to use their own custom domain for email.

What you get

An email service with fast search, snoozing, pinning, and offline access, bundled with calendar and contacts apps that sync across devices. Masked Email lets you create unique aliases per signup to hide your real address, and the service blocks tracking pixels and does not mine your data or show ads. Custom domain support and migration tools for importing existing mail, calendars, and contacts are included.

How it works

Sign up for a free 30-day trial (no credit card required) via the web, iOS, or Android app, optionally connect a custom domain, then use built-in migration tools to import mail, calendars, and contacts from your previous provider before continuing to use Fastmail's webmail, calendar, and contacts apps or any standard IMAP/JMAP-compatible mail client.
