The reporting manager of the user who completed the task.
The second-level reporting manager (manager’s manager).
Any user with a designated role (e.g., Manager, Auditor) configured to receive completion alerts.
The user completing the task may or may not have a territory assigned (depending on your configuration).
Emails are sent only if the recipient’s assigned territory matches the customer’s territory involved in the task.
If the user in the specified role does not have the matching territory, the email will not be sent.
