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.

Kami

  • The free Basic plan exposes only about 10 of the 40 or more tools
  • Google Classroom, Schoology, Canvas and Microsoft Teams integrations require the Teacher plan at $149 per year
  • School and district licensing including domain wide deployment is custom priced and requires a quote
  • Non education users pay separate Workplace plans at $85 or $220 per year rather than the education rate
  • A dedicated account manager is only available on the School or District plan
