Limits worth knowing
- There is no free plan. After the 30-day trial every account is paid, and Fastmail does not refund unused subscription time.
- The Basic business plan has 6 GB per user and leaves out custom domains, Scheduled Send, Snooze and third-party mail apps.
- Storage beyond the plan allowance is a paid add-on, up to 300 GB per user.
- Listed prices are tax-exclusive.
