The short version

  • Only Windscribe has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Windscribe free tier's 10GB cap still requires email confirmation and social sharing to unlock, unlike some no-strings-attached competitors.
  • They diverge on capability: Fastmail covers Custom domain hosting, Windscribe covers Firewall / default block.
  • 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.

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.

Windscribe

  • Free tier's 10GB cap still requires email confirmation and social sharing to unlock, unlike some no-strings-attached competitors.
  • Build-A-Plan's low cost only covers selected locations, so broad global coverage still requires the full Pro plan.
  • Server speeds and streaming reliability are inconsistent compared to larger premium VPN providers.
  • Customer support is primarily ticket/community-based rather than live chat for lower tiers.

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

Fastmail: Can I use my own domain?
