Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Coggle
- Free plan limited to 3 private diagrams; upgrade required for more private diagrams
- Organisation plan requires per-member billing with minimum 3-member commitment
- Enterprise pricing requires email inquiry with no published rates
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.
