Opt-in Management is the process where users give permission to receive messages by sending specific keywords (like "START" or "YES") to subscribe to your communications. Opt-out Management is the process that allows users to stop receiving messages by sending keywords (like "STOP" or "UNSUBSCRIBE") to unsubscribe from your messages. Together, they help you manage user consent and ensure compliance with messaging regulations.
