 # Opt-Out management overview
-The Opt-Out Management API enables Azure Communication Services customers to manage opt-out requests for SMS messages. It provides a self-service platform for businesses to handle opt-out requests, ensuring compliance with regulations and protecting customer privacy.
+The Opt-Out Management API enables you to manage opt-out requests for SMS messages. It provides a self-service platform for businesses to handle opt-out requests, ensuring compliance with regulations and protecting customer privacy.
 Currently, opt-out handling includes configuring responses to mandatory opt-out keywords, such as STOP/START/HELP. The responses are stored and the list of opted-out numbers is maintained in the Azure Communication Services Opt-Out database. This database management is automatic.
 The Opt-Out database contains entries added when a recipient sends an opt-out keyword. An entry includes the fields: Sender, Recipient, and Country. If a recipient opts back in, the corresponding entry is deleted.
 To learn more about how opt-out is handled at Azure Communication Services, read our [FAQ](https://learn.microsoft.com/azure/communication-services/concepts/sms/sms-faq#how-does-azure-communication-services-handle-opt-outs-for-short-codes.md) page.
