Is it possible to have 1 site, 2 domains and 2 email addresses?

Hello!

I'm a Graphic Designer and had my portfolio site for a while using my name as my URL. I've since gone freelance full time and am changing my business name so I'm redesigning my site. 

I have an email address that links with my original domain but now that I've switched my company name I would like to have an email address with that .com as well, BUT I still want to keep the original email address too. 

How do I do this though squarespace? Even though I have two domains linked to my site/account it seems to only allow me to have one email address. 

Help would be appreciated as I'm soo close to launching :) 
Thank you!
