The short version

  • Each has a real cost: Akiflow no native data export feature - tasks cannot be exported to CSV, JSON, or other standard formats; 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: Akiflow covers Universal inbox, Fastmail covers Custom domain hosting.

Where each one falls short

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

Akiflow

  • No native data export feature - tasks cannot be exported to CSV, JSON, or other standard formats
  • Mobile app integrations limited to 7 native apps compared to 30+ on desktop and web versions
  • Designed for individual users only with no team collaboration features or shared workspaces
  • No native project management capabilities to group related tasks or track project-level progress
  • Limited task-to-event conversion functionality restricting workflow flexibility

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.
