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.

iA Writer

  • Pricing varies by platform: Windows $29.99 while Mac/iPhone/iPad cost $49.99, creating $20 premium for Apple platforms
  • One-time purchase model means major version updates may require additional payment beyond initial purchase
  • Update schedule uncertain, making it unclear when new versions become available and whether paid upgrades will be required
