- Alerts: Mail Message Recipients: Use the icon to add new recipients. Each email address must be in a standard format, such as user1@example.com and user2@example.com.
- Alerts: Mail Message Format: Select the format of the email alert message. Select json if you want the message to be parsed by a script or program.
