The short version

  • Each has a real cost: Mailbrew free tier has limited digest count, source limits, and length restrictions; 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: Mailbrew covers Custom digests, 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.

Mailbrew

  • Free tier has limited digest count, source limits, and length restrictions
  • Requires upfront configuration and personalization effort to find settings suited to individual needs
  • Shows all sources without deduplication, potentially resulting in duplicate content in digests
  • Depends on upstream third-party APIs (Twitter, Reddit, YouTube) that can change terms or rate limits independently

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.
