Where each one falls short

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

Courier

  • Enterprise-only features like RBAC and EU data residency require a custom sales conversation rather than a published plan.
  • Pay-as-you-go per-send pricing on Business can become costly at very high volume compared to flat committed pricing elsewhere.
  • The free Developer tier is capped at 10,000 sends per month, which is limiting for growing production apps.

Mattermost

  • No published pricing on public website; requires sales contact for all tiers
  • Three tiers (Professional, Enterprise, Enterprise Advanced) have feature differences but no cost transparency
  • User scaling caps differ between tiers without public price justification
