Sent.dm

Sent.dm is a developer-focused API that lets you send messages across multiple communication channels—SMS, WhatsApp, and RCS—using a single integration. Instead of building separate connections for each provider and managing their unique rules, you send one request to Sent.dm. It takes care of delivering your message through the best available channel for each recipient. This simplifies the process of reaching users reliably, whether you're sending a two-factor authentication code, an order update, or a promotional offer.

The service works by acting as an abstraction layer. Your application sends a message to the Sent.dm API, which then handles the complex backend work. It validates phone numbers, checks compliance requirements like 10DLC for SMS and template approval for WhatsApp, and automatically transforms your message content to fit the format of the chosen channel. A key feature is its intelligent routing; it checks which channels are available for a contact and can automatically fall back to SMS if a WhatsApp message fails to deliver. You can track the entire journey of each message, from the moment it is queued to when it is delivered and read.

This tool is ideal for development teams building applications that require reliable user communication. It removes the burden of managing multiple provider contracts and dealing with the technical quirks of different messaging systems. Use cases include sending appointment reminders, shipping notifications, or any scenario where you need to ensure a message reaches a user promptly. By consolidating messaging infrastructure, Sent.dm helps teams ship features faster and maintain a more reliable communication system.
