HOW IT WORKS
An event-driven core, built for billions of messages
Every message — whether it enters through the web campaign manager or the REST API — flows through a load-balanced gateway into Sendo's event stream. Dedicated channel services consume each event and hand it to carrier-grade connectors, while every status update streams back into one reporting database. No single point of failure, no channel silos, and analytics on everything.
