RCS (Rich Communication Services) is a standard that supports rich features in text messages, including high-quality GIFs, videos, and other interactive elements. Android phones already support it and Apple will likely support it as part of the upcoming iOS 18 update. Marketers' usage of RCS will likely continue to grow, especially once it's supported on Apple devices. Some example use cases include sending personalized messages, asking for the user's location to recommend an action in the user's physical environment, and embedding a carousel with five or more options that users can swipe through.
