The short version

  • Only Courier has a free tier, so it costs nothing to try first.
  • 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.; Telnyx the advertised per-message price excludes US 10DLC registration fees and carrier surcharges, so American A2P traffic costs more than the rate card row suggests.
  • They diverge on capability: Courier covers Multi-channel sending, Telnyx covers Published per-destination rate card.
  • Prices and features above were last checked on 31 August 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.

Telnyx

  • The advertised per-message price excludes US 10DLC registration fees and carrier surcharges, so American A2P traffic costs more than the rate card row suggests.
  • Support and the partner ecosystem are smaller than the market leader, which matters most during an incident rather than during evaluation.
  • The cost advantage only becomes material at volume, so low-traffic projects save little while giving up ecosystem breadth.
  • Toll fraud controls need configuring properly, because a misconfigured voice account can accumulate serious cost quickly.
  • Product breadth is strong for voice and messaging but thinner for adjacent channels such as video, so multi-channel products may still need a second vendor.

Answered from the vendors’ own pages

Courier: What does Courier cost?

Courier has three plans: Developer is free for 10,000 sends per month, Business is pay-as-you-go at $0.005 per send, and Enterprise is custom-priced with volume discounts.

Source
Telnyx: How much do per-message rates vary between countries?

By more than an order of magnitude. US A2P SMS is priced in small fractions of a cent per segment, while some international destinations run to several cents or more per message. Always price your actual destination mix rather than a headline US rate.

Courier: Is there a free plan, and what are its limits?

Yes, the Developer plan is free and includes 10,000 notification sends per month along with journeys, broadcasts, the MCP server, CLI, SDKs, and email support.

Source
Telnyx: Are 10DLC fees included in the published price?

No. US A2P messaging requires brand and campaign registration, and those one-off and monthly fees plus per-segment carrier surcharges are added on top of the per-message rate.

Courier: How is usage metered?

Courier bills based on the number of notifications sent, not on team size or number of channels used, with Business plan sends charged at $0.005 each.

Source
Telnyx: Why does the private network matter?

Voice quality degrades with jitter and packet loss on the public internet. Carrying traffic on a private backbone with direct carrier interconnects is what the quality claim rests on.
