The 'Reply-To' field dialog box

 

The 'Reply-To' field dialog box allows you to choose the 'Reply-To' field of the form mail. You can either select a 'fixed' field or choose to have the value of a field from the form itself.

 

If your form has a field to collect the email address of your visitor, then select the field as the 'Reply-To' field. This helps in replying to the form mail quickly. When you receive an email from a form submission, you can just press the 'Reply' button in your email software to reply to the visitor who submitted the form.
