Web form set-up

Hello, 
I currently have a form I used in DocuSign as a powerform. I am moving it over to Adobe as a web-form. I need to have a hyperlink in my email to clients. I need two signers (they can be the same or different). The first person will complete the form and the second signs off on it. The link will be clicked on by different clients and will change. How can i set up the web form that way? I can’t seem to get pasted the email box without putting in an email (which I won’t have)
