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.

PDF Expert

  • Pricing displayed in AED (United Arab Emirates Dirham), not widely recognized currency
  • Essential and Pro plans offer identical features despite different pricing
  • Lifetime plan limited to Mac only
  • New features beyond initial purchase may cost extra
