The short version

  • Only Spark Mail has a free tier, so it costs nothing to try first.
  • Each has a real cost: Motion no free plan; starts at $19/month per user; 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: Motion covers AI auto-scheduling, 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.

Motion

  • No free plan; starts at $19/month per user
  • Mobile app is significantly less capable than desktop version
  • Requires adding deadlines, time estimates, and priorities to tasks to function effectively
  • Limited advanced project management features compared to dedicated PM tools like Asana or ClickUp
  • UI can feel cluttered and has a steep onboarding curve

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.
