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.

Mullvad VPN

  • Offers no free trial or free tier, unlike several consumer VPN competitors.
  • Lacks a bundled tiered structure, so there is no cheaper limited plan for occasional users.
  • Server network and streaming-unblocking performance is smaller than large mainstream VPN providers.
  • No annual discount, meaning long-term subscribers pay the same monthly rate as short-term users.
