You can delete an instance of a custom email alert, such as when your organization no longer requires its use. When you delete an instance, you remove the instance and any historical information about its send process.
Tip: Rather than delete an instance of a custom email alert, you can disable the instance. When you disable an instance, the program retains the instance and information about its process history, but users do not receive alerts based on the instance. For information about how to disable an instance, see Disable or Enable an Instance of a Custom Email Alert.
To delete an instance of a custom email alert from the record of the email alert, select it under Instances and click Delete. When the confirmation message appears, click Yes. You return to the record of the email alert.
