ClickSend
ClickSend, an Australian company in the Sinch group, sells SMS, MMS and RCS through a REST API and a web dashboard. Credit is prepaid: the SMS rate depends on the destination country and on the size of the last top-up (Boost, Growth, Scale and Enterprise tiers). New accounts get a 14-day trial with AUD 2 of credit; email and voice are closed to new customers.

Strengths, weaknesses and fit
Strengths
- Official MCP server
- Test mode or test credentials documented
- Official SDKs in 10 languages
Weaknesses
- No permanent free tier
- More expensive than most peers for SMS ($32.77 vs median $10.95 for 1,000 outbound SMS / month)
- Webhooks are not signed
- No OAuth 2.0 — API keys only
- Limited channels: SMS only
Not a fit if…
- you need to run in production without paying
- price per message is your main criterion
- you must verify that callbacks really come from the provider
- you build a multi-tenant app that acts on customers' own accounts
- you want several channels from one provider
