Hello Yung Jen ,

In Amelia, notifications are sent to Customer and to Employees, and you can configure this when you go to Amelia -> Notifications page. If you want to add some additional email addresses to which all notifications from Amelia will be sent as well, you can do that by adding these email addresses to the Send all notifications to additional addresses:  field which you will find in Amelia -> Settings -> Notification settings. When you add one email press Enter and it will be saved, so you can then add another one, etc. Please note that to these email addresses all notifications that are sent from Amelia (to customers and to employees) will be sent as well. There isn't another option to add additional emails for some notifications only. 

If you have any further questions feel free to ask.
