Sample of Email notification after someone submits your form. 

Now, to add another user to receive an email notification when someone submits your form, you can create a separate email notification with the other user's email address set up in it. 

However, if you want you and the sub-user receive the same email notification, you can just add the email address of the sub-user to the original notification separated by a comma. Click the notification you want to edit by clicking Emails button from the toolbar, then, the window below will appear.
