Our verdict on Fastmail Calendar

Fastmail Calendar is a calendar service integrated with Fastmail’s email, contacts, and productivity apps. It supports personal, family, and business use through shared calendars, event invitations, RSVP updates, calendar groups, side-by-side views, and multiple time zones. Access is available on the web, Windows, macOS, Linux, iOS, and Android, making it suited to users who want one calendar service across different devices and operating systems.

Pricing is structured around Fastmail plans rather than a separate calendar-only subscription. The Basic plan costs $4 per user per month and includes 5 GB of mail, calendar, and contacts storage, shared calendars, and web and mobile access. Individual costs $6 per user per month with personal and work calendars, 60 GB total storage, and third-party app support. Duo costs $10 per month for two users, while Family costs $14 per month for up to six users. Business Standard costs $6 per user per month, and Business Professional costs $10 per user per month with an email retention archive. A 30-day free trial is available.

Its strongest fit is for households, teams, and individuals that need two-way synchronization with Google Calendar, iCloud Calendar, Outlook, or CalDAV-compatible clients. Google and iCloud import and synchronization, shared company or family calendars, invitations, and time-zone support cover a broad set of calendar workflows. The trade-off is that anyone seeking only a standalone calendar must also choose a Fastmail plan, and plan selection affects storage and business features. Choose it for cross-platform access and external calendar coordination; consider an alternative if a free plan or calendar-only subscription is essential.
