Send auto email to respondents with attached PDF submission

I am curious how a form submission will be sent to me.  Will it include the user email as the handle following the form submission or will the handle and form info come from something like no-reply@jotform.com? 

Main goal is to send user who completes a form an automatic pdf / xlsx attachment following their submission (triggered send).  They will be asked for an email on the form they complete. 

Thanks for the help

You can attach PDF submission to the email autoresponder that will be sent to your respondents.

You can create/customize the PDF submission on the PDF Editor page of your form.
