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.

KakaoTalk

  • KakaoTalk has minimal relevance outside South Korea, so it is the wrong tool for reaching audiences anywhere else.
  • Standard chats are not end to end encrypted by default; a Secret Chat mode with encryption exists but must be turned on per conversation.
  • Concentration of messaging, payments, banking and mobility data inside one company creates a single point of both convenience and risk that has drawn scrutiny from Korean regulators.
  • Plus Friend business messaging costs scale with volume, so a company messaging its full Korean customer base regularly can face a meaningful recurring bill.
  • A 2022 data centre fire caused a multi-day outage across KakaoTalk and related Kakao services, which showed how much everyday activity in Korea depends on a single provider staying online.
