Email only or pay via PayPal and Email

We have a form with products. Customers can choose to pay by check or pay via PayPal. We have the PayPal addon. If they choose to pay by check we want the form entries to only be emailed to us. If they choose pay by PayPal we want to process via PayPal and receive an email. How do I set that up?

I recommend opening a support ticket for this issue and they can walk you through the process. Thank you.
