Add additional E-mail Account to Your Paypal Account

I just learned that you can add up to 8 different e-mail accounts to your Paypal account. I just started doing online surveys, product testing, mystery shopping, and other junk mail that I don't want going to my personal e-mail. The only problem was, how can I do that if it says, "you have to have use the e-mail address that is linked to your Paypal account". I was baffled. Until, I read you can add more accounts; therefore, you don't have to get all the possible "junk" mail in your personal e-mail. Hope this helps you out too!
