- RCS upgrades SMS with branded conversations, images, carousels, and suggested replies, delivered natively.
- Twilio Programmable Messaging supports RCS Business Messaging as a first-class channel, reusing existing SMS APIs.
- An RCS campaign involves an RCS Sender, Messaging Service, Content Template, campaign script, and webhooks for status and inbound replies.
