The short version

  • Each has a real cost: 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.; Google Slides fonts are limited to what Google hosts, so a brand's licensed typeface cannot be installed, and decks built to a corporate template either substitute a lookalike or lose the visual identity the template exists to enforce.
  • They diverge on capability: Canary Mail covers AI Copilot, Google Slides covers Simultaneous editing.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • A user who wants AI summaries without sending mail content through an unfamiliar third party indefinitelynot Google Slides
  • Someone consolidating several IMAP accounts into one client with unified searchnot Google Slides

Google Slides

  • A deck several people must build at once before a deadline, where merging emailed versions would be the actual failure mode.not Canary Mail
  • Recurring reports where the charts should update from a spreadsheet rather than being pasted in again each time.not Canary Mail
  • Teaching and classroom use, where the tool is free and runs on inexpensive hardware.not Canary Mail
  • Sharing a deck with people outside the organisation by link rather than as an attachment that immediately goes stale.not Canary Mail

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.

Google Slides

  • Fonts are limited to what Google hosts, so a brand's licensed typeface cannot be installed, and decks built to a corporate template either substitute a lookalike or lose the visual identity the template exists to enforce.
  • PowerPoint conversion is lossy in both directions, with animations, transitions, embedded video, diagrams and precise positioning all liable to shift, so a deck that must end up in a client's PowerPoint needs checking slide by slide and is often rebuilt.
  • Offline access has to be arranged before the connection is lost, so a deck not marked for offline use in advance is simply unavailable, which is a recurring failure on the way to present at a customer site.
  • Animation, master slide control, image editing and typographic precision sit behind PowerPoint and Keynote, so design-led work meets a ceiling that no add-on removes and the designers work elsewhere.
  • The governance features an organisation eventually needs, including retention and legal hold, data loss prevention and data residency controls, belong to higher Workspace editions, so a tool adopted because it was free carries an upgrade cost that surfaces only when compliance asks.

Answered from the vendors’ own pages

Canary Mail: Does Canary Mail host my email?

No, it is a client over Gmail, Outlook, iCloud or IMAP accounts you already have.

Google Slides: Is Google Slides free?

Yes, with a personal Google account and no time limit or feature gate on the editor. What costs money is Workspace, which adds storage, administration and the governance controls.

Canary Mail: Is the lifetime licence still available?

Canary has offered a one-time lifetime purchase alongside its subscriptions; check current pricing on their site as terms have changed over time.

Google Slides: Can I open and edit PowerPoint files?

Yes, and .pptx files can be edited directly in Drive. Complex decks lose animations, effects and exact positioning in the conversion, so check anything that came from a designer.

Canary Mail: Does PGP encryption work automatically?

Only between users who both have PGP set up; it does not encrypt mail to recipients without it.

Google Slides: Does it work offline?

Yes in Chrome, but only if the file was made available offline beforehand. It cannot be arranged after you have lost the connection, which is when people usually try.

Google Slides: Is it good enough for a client-facing deck?

For a standard business deck, yes. For a design-led deck using brand typefaces and animation it will hold you back, and the export to PowerPoint will not be clean.
