RCS vs In-App Messaging, common questions.
What is the difference between RCS and in-app messaging?
In-app messages only reach customers while they are inside your app. RCS reaches them in the phone’s messaging inbox at any time, whether or not they have your app open or installed.
Is RCS better than in-app messages for re-engagement?
For bringing people back, yes. In-app messages cannot reach someone who has not opened the app. RCS lands in an inbox they already check, with a verified sender and tappable actions.
Can RCS and in-app messaging work together?
Yes. Use in-app messages for people actively using your product, and RCS to reach everyone in their native inbox, with automatic SMS fallback so no one is missed.
