RCS

RCS is a messaging standard designed as a successor to SMS, supporting verified sender profiles, images, carousels, suggested replies and delivery and read receipts. For brands it offers app-like conversations inside the native messaging inbox without asking anyone to install anything. Availability still depends on the recipient's device, carrier and country, so any campaign needs an SMS fallback for people who cannot receive it. Treat RCS as an upgrade layer over SMS rather than a replacement channel.
