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.

Todoist

  • No built-in time tracking for tasks; requires third-party integration like Toggl
  • Free plan limited to 5 personal projects only
  • No Gantt charts, resource allocation, or advanced project management features for large enterprises
  • Phone support not available; email and help center only
  • Calendar view and advanced filtering only available on paid plans
