Quick answer. RCS matters because it fixes business messaging’s two core problems — lack of trust and lack of richness — at the exact moment messaging is becoming the primary brand-to-customer interface. It restores trust with verified, branded senders (countering the phishing that plagues SMS) and adds engagement with rich, interactive content, all in the inbox customers already open and without an app. With Apple’s 2024 support making it near-universal, RCS turned from a promising standard into the foundation for AI-driven, conversational, transactional messaging.
The deeper reason RCS matters is timing: it arrives just as AI agents and conversational commerce need a trusted, rich, universal channel to live in. RCS is that channel — which is why analysts increasingly treat it as core infrastructure rather than a nice-to-have.
