Problem
Developers building applications that need to reach customers across multiple channels face significant integration complexity, requiring separate APIs for SMS, email, WhatsApp, and iMessage. Additionally, messaging platforms often impose carrier-specific fees, complex regulatory compliance requirements like A2P 10DLC registration, and usage caps that create unpredictable costs and operational overhead.

The platform includes a rich dashboard for managing numbers and messages, plus SDKs and documentation that enable production workloads to be deployed in under 30 seconds. The API is designed so developers can begin sending production traffic in under five minutes with fewer than ten lines of code.
