Display question on received email notification despite not being required / filled?

We use JotForm for our online employee application form. Is there a way to "set" the form so that despite a question not being required, it still shows on the completed application (sent by email) as empty or not answered?

For example: "Starting Salary" is a question on our form that is not required to answer - but when we receive the application we would still like the question to show (even if it isn't answered). 

Thank you for contacting us.

This is possible to show the empty fields in the emails. First, open the email notification via the form settings.

Then, switch the 'Hide Empty Fields' option to 'No' via the Advanced tab, and save your changes.

If you need any further assistance, please let us know.
