Can we send approval/deny notification to users along with the approved/denied form which was filled by users?

Since each user may send multiple filled forms in one day or one week, users may not know which form was approved or denied by approver when they receive approval/deny notification. So it'd be better if users can view the content of the filled form that was approved or denied by approver when they received such notification email.

Yes, you can send the form along with the status of the form. You need to enable the Send on Edit functionality and the PDF attachment feature in your Autoresponse email which would send the PDF attachment of the form to the users who have filed your form.
