The short version

  • 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.; Sessions it will not replace Microsoft Teams or Google Meet for everyday internal calls, so most buyers end up paying for two conferencing tools and asking staff to know which one to open.
  • They diverge on capability: Courier covers Multi-channel sending, Sessions covers Agenda blocks.
  • Prices and features above were last checked on 1 September 2026.

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.

Sessions

  • It will not replace Microsoft Teams or Google Meet for everyday internal calls, so most buyers end up paying for two conferencing tools and asking staff to know which one to open.
  • The vendor is small and European, competing directly against Zoom and Microsoft, so any team standardising a customer-facing process on it should keep an exit plan and export recordings regularly.
  • The preparation model that makes it good is also overhead; a meeting nobody had time to structure runs no better in Sessions than anywhere else, and teams that will not prepare get no benefit from the licence.
  • Lifetime deals sold through AppSumo mean a segment of the user base pays nothing recurring, which shapes support priorities and has previously produced friction when plan terms changed.
  • It is browser-only, which keeps participation frictionless but leaves it more exposed to browser and network conditions than a native client, and there is no desktop application to fall back on when a call misbehaves.
