How to hide empty fields in our email notifications?

Also due to all our clients filling in our form when we receive submissions it shows all of the boxes and questions, I would like to know if the email sent to us is able to show only populated fields.

It can be achieved by enabling the option to hide empty fields on Email from Advanced settings in the Form preferences.

Please refer to the following guide that can guide you through step by step process.
