How can I setup an Autoresponder?

I would like the sender of the form to receive an email confirmation that their form was processed. I looked everywhere for the setting, but can't find it. Thanks.

What you need to add is called an Autoresponder. On your Form Builder, navigate to SETTINGS > EMAILS > click the ADD (+) icon then select the AUTORESPONDER.
