e-mail form

Dear,
I make a form to subscription for a sport event ( https://www.cnsavio.it/iscrizione-48-settimana-velica/ ) where I have 3 e-mail address, one is mandatory other optional.
Is possible to use all of them as destinatary for the confirm message? Alternatively, use all of the as “CC” e-mail for the admin e-mail?

Feature suggestion: make a pdf with the form data to attach at the e-mail.

Thanks.
