Where each one falls short

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

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.

Sunsama

  • Pricing is higher than some competitor daily planners at $17+ per month
  • Requires consistent daily engagement with the planning ritual to be effective
  • Limited customization of the daily planning framework compared to more flexible task managers
