Best use case: A solo business owner using a custom email domain

Fastmail makes sense if email is the job you need done. I would compare its inbox and calendar with your current provider during the trial, especially shared addresses and third-party mail apps.

Fastmail makes sense if email is the job you need done. I would compare its inbox and calendar with your current provider during the trial, especially shared addresses and third-party mail apps. A domain is still a separate purchase. If you already pay for an office suite with mail included, compare the extra cost with the value of a dedicated email service.

  • Basic has restrictions

  • A business needing more mailbox storage or retention

About Fastmail

Manage business email, contacts, and calendars without a full office suite. Fastmail supports custom domains, shared addresses, and team administration, with different storage levels by user. Businesses can mix plans. At least one Standard or Professional user is needed to share custom domains with Basic users. Fastmail focuses on email, calendars and contacts rather than a full document suite. For business accounts, Basic has smaller storage and fewer client options; Standard adds custom-domain addresses and third-party mail-client support. Professional increases storage and adds retention features. A domain is still a separate purchase. If you already pay for an office suite with mail included, compare the extra cost with the value of a dedicated email service.
