The short version

  • Each has a real cost: Everything searches filenames only, not file contents, which is the deliberate trade for its speed; 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: Everything covers Instant results, 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.

Everything

  • Searches filenames only, not file contents, which is the deliberate trade for its speed
  • Windows and NTFS only: no macOS or Linux build, and non-NTFS volumes fall back to slower indexing
  • Requires administrator rights to read the Master File Table

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

Everything: Is Everything free?

Yes, free to use with donations accepted.

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.

Everything: Why is it so much faster than Windows Search?

It reads the NTFS Master File Table directly instead of crawling the filesystem, so indexing a whole volume takes seconds.

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.

Everything: Can it search inside files?

Only in a limited way. It is built for filename search, and full content search is not what it is for.

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.
