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, Linux, macOS, web, and Windows. Users can import calendars from Google, iCloud, and other services, search instantly, and arrange 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 and synchronize edits when connectivity returns. Fastmail offers individual, family, and business plans; business options include shared calendars and administrative controls. A 30-day trial is available, but there is no free plan. Basic costs $4 a month and includes 6 GB storage per user with shared calendars. Individual costs $6 a month for one person and 60 GB total storage. Other listed plans include Standard at $6 per user/month, Duo at $10 a month, Professional at $10 per user/month, and Family at $14 a month. Fastmail was founded in 1999 and is headquartered in Melbourne, Australia.
