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.

WhatsApp

  • Consumer app messaging and calling is free, but the vendor notes carrier data charges may apply
