customized confirmations or popups

Hi,
I was wondering if it’s possibile to customize the confirmation emails that are being sent.
How can I change the template of the email that is being sent to my users after they hit submit? Since I have a few conditional rules, I don’t want to show them the parts they’ve never seen in the form.

Also, is there a way to show a custom elementor popups after they hit “submit form”?

Thank you
