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.

Nitro PDF

  • Specific per-seat pricing is not published; must contact sales for individual plan pricing and volume discounts
  • SSO and enterprise features (Azure Information Protection) are limited to Plus tier, not available in Standard
  • Plans support up to 20 licenses online; teams needing 20+ users must contact sales

Nitro offers Standard and Plus tiers for PDF tools, plus Nitro Sign for e-signatures. Standard is an annual subscription with unlimited users and basic PDF features. Plus adds SSO, domain control, and Azure Information Protection. Specific pricing requires contacting Nitro sales. A 14-day free trial is available without a credit card.
