The email or SMS will not send out if the user isn’t opt-on for SMS & Email.
{% endhint %}

To configure SMS Opt-in or Opt-out for users in bulk, follow these steps:

1. Go to **Bot -> Bot Users**.
2. Check the box next to the user(s) you want to configure.
3. Click on **Bulk Action**.
4. Select **Set SMS Opt-In** or **Set SMS Opt-Out**.

This configuration will include or exclude the user from SMS notifications sent by the bot. If SMS Opt-in is not enabled, the system will avoid sending SMS to that user.
