A few tips on how to spot those scammers:
Paypal will never send you an email asking you to click a link to login, if you receive a checkout link, always make sure the link starts with
www.paypal.com. If the link is an IP address, or something else than
www.paypal.com, then it is spam / scam.
If you receive an email like that, check the full headers, it should show the originating server that sent the email, send the headers to paypal security or one of the anti-spam sites, they should deal with them swiftly.
There are spammers that will gather email addresses in order to send those spam emails, they don't know if you have paypal or not, they just spam a couple million emails hoping to scam someone.
It's called phishing:
