## How people opt in

Recipients can join by texting any of these keywords to your custom number:

* **JOIN**
* **START**
* **YES**
* **SUBSCRIBE**
* **UNSTOP**

## Reaching your opted-in contacts

When you create a text campaign, select the **Opted-In by Text** contact group to send messages to everyone who has texted in.
