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.
Proton Mail
- Paid plan pricing not displayed on vendor site
- Free tier limited to 1 GB storage
- Free tier limited to single email address
