Can I set myself up to receive Alerts as an Account Manager AND a Ticket Manager?

Can I set myself up to receive Alerts as an Account Manager AND a Ticket Manager (when I'm the Ticket's assigned technician)?

Yes, you can select all of the Alerts roles and receive Alerts for events which relate to all or some of them.

Note that when you are the Account Manager and Ticket manager of a Ticket, you will receive a single Alert for all events related to this Ticket. You will receive the Alerts through your role as the Ticket Manager (Account Manager Alerts are eliminated in this case to avoid duplicate Alerts).
