The short version

  • Each has a real cost: Sejda free tier is restricted by page and hourly limits and limited file uploads; 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.

Where each one falls short

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

Sejda

  • Free tier is restricted by page and hourly limits and limited file uploads
  • OCR is capped at 100 pages even on paid plans
  • File uploads are capped at 500MB per file on paid plans
  • The 30 percent annual discount requires paying for a year upfront rather than monthly

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.
