Where each one falls short

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

Canary Mail

  • PGP encryption only protects a message if the recipient also supports and uses PGP, so most everyday mail to non-technical contacts stays unencrypted regardless.
  • Team and shared-inbox features are minimal compared with Spark or dedicated tools, so it does not suit a support team out of the box.
  • The lifetime purchase price and terms have shifted over past versions, and buyers should confirm current lifetime pricing directly before assuming it still applies.
  • AI features still require sending thread content to a processing service to generate drafts and summaries, so the privacy story is stronger for encryption than for the AI layer itself.
  • Windows and Android apps have historically received updates later than the macOS and iOS versions.

Gamma

  • Free plan limited to 400 non-renewable credits, requiring paid plan quickly
  • Credit rollover capped at 2x monthly allocation, forcing month-to-month spending
  • Refund window limited to 3 days with usage thresholds restricting claims
  • Per-seat pricing on team plans increases costs for large organizations
  • Studio Mode limited to Ultra plan, restricting advanced editing to highest tier
