Orchestration

Every message on the channel that converts.

Sintalk determines the best channel for each contact in real time: it starts with the most effective channel and automatically switches to the next one if delivery fails. No contacts are missed, and no messages go to waste.

  • RCS primeiro: mídia rica e perfil verificado quando o aparelho suporta.
  • SMS de fallback: alcance universal quando o RCS não chega.
  • Voz e WhatsApp: acionados por regra para urgência ou conversa.

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.
