You can set up using the following under the Emails section.

1. For you to receive submission notification , use the 'Notifications' template

Select the sender email, at the bottom right specify the recipient email

Next edit the template for the message body

2. For the sender to receive a copy of their submission use the 'Auto Responder' template

Make sure and email field is available in the form

In the template set the sender details and select the field with the filler's email address in the bottom right

Lastly Edit the message template
