When a [Dynamic Rule](https://waap.docs.link11.com/v2.20.2/product-walkthrough/security/dynamic-rules) is violated, Reblaze can send immediate alerts to a list of one or more email addresses and hooks (e.g., Slack). 

In addition, a cumulative report of the previous week's violations can be sent to one or more email addresses. 

This section defines one or more **Notification Groups** for these notifications. Clicking on the "**+**" button on the right will display this dialog:
