Introduction to RCS

Rich Communication Services (RCS) is the next generation of text messaging. Unlike traditional SMS, RCS enables branded sender identification, rich media content (images, videos, GIFs), and interactive messaging features that help you create more engaging customer experiences. 👉 Sign up for a demo of RCS

RCS allows you to send media rich content with interactive features, directly from a branded sender identifier.
