Email - See respondents' email address instead of jotform

How can we set up jotform to see the email address of the person who submitted or completed a form?

I understand that you want to see the respondent email address as the sender in the email notification received. if so, you may consider using Mandrill service to achieve your requirement. Please refer to the guide below:
