  • Each has a real cost: Courier enterprise-only features like RBAC and EU data residency require a custom sales conversation rather than a published plan.; Mattermost no prices are published for any of the three paid tiers (Professional, Enterprise, Enterprise Advanced); all require contacting sales

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 prices are published for any of the three paid tiers (Professional, Enterprise, Enterprise Advanced); all require contacting sales
  • Professional is capped at a maximum of 250 users, forcing a move to Enterprise for larger teams
  • Licenses are sold only as prepaid annual subscriptions, and organizations that exceed their licensed seat count must purchase additional seats on a prorated quarterly basis
