What Fastmail Calendar is
Fastmail Calendar is a paid calendar service integrated with Fastmail email. It supports shared calendars and two-way synchronization, with access through Android, iOS, web, Linux, macOS, and Windows. Users can import calendars from Google, iCloud, and other services, search instantly, and rearrange events with drag-and-drop editing. Schedules can be viewed in other time zones. When an event update arrives by email, Fastmail compares it with the previous version and shows the changes. Its apps support offline calendar management, syncing edits when connectivity returns. Fastmail offers individual, family, and business plans, with shared calendars on business options and administrative controls. The service includes a 30-day trial but no free plan. Listed monthly plans include Basic at $4 a month, Individual and Standard at $6 a month, Duo at $10 a month, Professional at $10 a month, and Family at $14 a month.
