# The SMS Campaign Component

You can use Twilio for Salesforce to send customized bulk SMS messages to all members of a campaign. Before you get started, you should recognize two important points:

* Anyone you send messages to as a part of a campaign [must have opted-in somehow to receive those messages](https://help.twilio.com/hc/en-us/articles/223134707-Industry-standards-for-opt-ins-for-US-short-codes).
* A Contact or Lead must have a **mobile phone number** on their record to receive a text message. Other phone numbers will not be used.

> \[!WARNING]
>
> Use of the SMS Campaign Component requires users to have access to the **Twilio Messaging** folder in order to display potential deliverability ratings. If a user does not have access to this folder and the reports it contains, the component will display an error.
