# Target actions

Integrating Mailrelay as a target lets you keep your subscriber lists updated, using information collected by other apps. Also, you can send newsletters to your groups every time an app is updated.

As a target, Mailrelay offers three actions:

* **New subscriber**: Records a new subscriber.
* **Delete subscriber**: Deletes existing subscribers.
* **Send campaign**: Sends a newsletter when your source app is updated.
