Orchestration

Every message on the channel that converts.

You set up the campaign, Sintalk delivers it and shows you what converts. SMS, voice, RCS with fallback: the platform orchestrates the approach you choose, measures each result, and reveals the path that generates the most revenue. You test it, we monitor it, and the conversions start rolling in.

  • Your choice, your way: voice call, RCS, SMS, or WhatsApp—whichever works best for you.
  • Automatic fallback: if a message cannot be delivered on one channel, it is forwarded to the next one in a cascade.

  • Sandbox on Day One: Test with a developer key before signing any contract.
  • Idempotence and logs: each trigger is traceable by ID, with no duplicate messages.

Why Sintalk

CPaaS delivers messages. Sintalk delivers revenue.

Global CPaaS providers treat your operation like just another ticket. Local providers deliver and disappear, without proving results. Sintalk brings the best of both worlds together: the infrastructure of a giant, the personalized attention of a partner, and a proven track record.
