Unsurprisingly, this is a fake "phishing" message. Aside from the poor English, I always hover over links before I click them, and I could see that this didn't go to the real PayPal website. (I've removed the dodgy link to stop anyone clicking it by mistake.) Also, it gets "SFAIL" status from an SPF check, i.e. the email wasn't sent from one of PayPal's mail servers.
However, suppose that I did believe that this was a real message from PayPal. It still doesn't make sense! They initially say that I should log in if "an unauthorized person has changed your email", which implies that I don't need to do anything if this was a legitimate change. They later say that they'll suspend my account if I ignore this message, but that would be rather harsh if I had actually added the new email address myself. In actual fact, the spammers know that this is a fake email address (because they made it up), but the real PayPal wouldn't know that, so the spammers are sabotaging their own attempt by relying on that knowledge.
I assumed that this was just incompetence on their part, but Microsoft Research have a different theory (link via The Old New Thing). That specifically applies to Nigerian scams, but the premise may apply here too. Basically, the scammers don't want to waste time making contact with people who will get suspicious, so they want to pre-select the people who are so gullible that they'll ignore all warning signs (e.g. glaring contradictions). I haven't read the whole research paper yet (since it's 14 pages of maths), but it's an interesting idea.
