The short version

  • Each has a real cost: 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.; Spark Mail several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • They diverge on capability: Google Slides covers Simultaneous editing, Spark Mail covers Smart Inbox.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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.

Spark Mail

  • Several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • It is a client over accounts you still pay for elsewhere, so the total cost is Spark plus whatever Gmail, Outlook or Fastmail plan you already hold.
  • The free tier lacks AI Copilot and summaries, so the features it is best known for sit behind the paid plan.
  • Team features are basic next to dedicated shared-inbox tools like Front or Help Scout, so a support team scaling past a few agents will likely outgrow it.
  • Windows and Android versions have historically lagged the macOS and iOS apps in feature parity.

Answered from the vendors’ own pages

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.

Spark Mail: Does Spark host my email?

No. It is a client that connects to Gmail, Outlook, iCloud or any IMAP account; you still need a mail host.

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.

Spark Mail: Does Spark store my email credentials on its servers?

For some features, including cross-device snooze and send-later sync, yes. It is part of how those features stay consistent across devices.

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.

Spark Mail: Is there a one-time purchase option?

No, Spark is subscription only for individuals and teams; the base client is free but AI and unlimited scheduling need Premium.

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.
