The short version

  • Only Enpass has a free tier, so it costs nothing to try first.
  • Each has a real cost: Enpass no built-in cloud sync of its own, so users must configure a third-party storage provider for multi-device sync.; Fastmail it does not provide end-to-end encryption by default, so users specifically wanting zero-knowledge mail should compare it against Proton Mail or Tuta rather than assume parity.
  • They diverge on capability: Enpass covers Offline vaults, Fastmail covers Custom domain hosting.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Enpass

  • No built-in cloud sync of its own, so users must configure a third-party storage provider for multi-device sync.
  • Mobile Lite tier caps vaults at 25 items, pushing active mobile users toward a paid plan quickly.
  • Lacks dark web monitoring and breach alerting found in some competing password managers.
  • Team/business plan lacks a native SSO login option comparable to enterprise-grade competitors.

Fastmail

  • It does not provide end-to-end encryption by default, so users specifically wanting zero-knowledge mail should compare it against Proton Mail or Tuta rather than assume parity.
  • Moving to Fastmail is a real migration with DNS changes for a custom domain, unlike installing a client such as Spark or Bluemail over an existing account.
  • There is no free tier at all, so a user just wanting to try it commits to a paid trial rather than a permanently free option.
  • Storage limits on the entry Basic plan are modest next to the free allowance Gmail gives, and heavy attachment users will need Standard or above.
  • Being based in Australia means it falls under Australian data access law, which some privacy-focused buyers weigh differently from Swiss or German jurisdictions used by Proton Mail and Tuta.

Not by default in the way Proton Mail or Tuta do; its privacy position rests on being subscription-funded rather than ad-funded.
