Can I receive email notification when someone completes a form?

We have multiple forms on our account for each department so I would only want to see my department's forms.

We have multiple users on the account so can the notifications be sent to a specific email address? 

Yes it is possible. You only need to set up an email notification to your form and input only a specific email recipient on the Notification Email settings. Please see this guide: Setting Up Email Notifications.

Let us know if you need further assistance.
