Contact form - How do I set which email the customers message gets sent to?

Hello, 

I built a contact form with a name section, email section, and message section, but this website is for someone else and I need to make sure that the message from the customer gets sent to his email. Is there a spot to to put in an email address for the customers email to go to? 

Thank you
