Each Interrupt rule lets you choose who receives its emails, so security alerts can go to leadership while performance alerts go to the account team.
Teams - all users in the selected teams receive email notifications. Pick one or more teams per rule.
Specific users - name individual recipients instead.
If no team is selected, notifications default to the Administrator team, so a critical alert can never go nowhere.
How to set recipients:
Open the rule's Adjust panel and click Edit notification recipients.
Choose Teams or Specific users.
Select the recipients and save.
