To stay free from complaints, implement opt-out management, allowing users to subscribe or unsubscribe using designated keywords.

### **Step 1: Define the keywords**.

1. Navigate to Channels 🡪 SMS 🡪 Opt-out Management.
2. Define keywords for users to opt in and opt out (e.g., "START" for subscription, "STOP" for un subscription).
3. Set up default messages for both opt-in and opt-out actions.
