RCS delivers rich, verified, interactive messages directly in your customers' native inbox — no app required.
RCS is the next-generation messaging protocol that replaces SMS. Businesses send branded, verified messages with images, carousels, interactive buttons and real-time read receipts — all within the native Android Messages app.
Unlike WhatsApp, RCS requires no download, no third-party opt-in — it lives natively on Android and iOS 18+.
