The business messaging landscape is poised for a major transformation with the adoption of Rich Communication Services (RCS) Business Messaging, as more carriers support this feature and businesses can now create engaging, branded experiences directly in customers' messaging apps. RCS offers several key features, including rich cards, carousels, interactive elements, read receipts, and verified brand presence, which creates immediate trust and recognition. The channel is currently undergoing an inflection era, with accelerated development, and will enter a rapid growth phase in 2026. A new pricing structure, including three-tiered models for basic messaging, single rich messages, and conversational messaging, opens up possibilities for customer service and AI-driven conversations without per-message costs spiraling out of control. The verified brand presence is critical to trust and engagement, with US carriers collaborating on verification standards. Businesses should begin preparing for the rapid growth phase by evaluating existing SMS campaigns, gathering brand verification materials, experimenting with basic RCS features, and planning for more sophisticated implementations as the ecosystem matures.
