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.

MailerLite

  • Free plan caps at 250 subscribers, 2,500 monthly emails and 2 user seats
  • Comfort plan is limited to 3 user seats; unlimited seats require the Power plan
  • Pricing scales with subscriber count and email volume rather than a flat seat rate, and resets to the plan's subscriber ceiling each billing anniversary
  • Annual billing earns only a 10% discount versus monthly, smaller than many competitors' annual discounts
