I had one from PayPal this morning, telling me that there was a problem with my account due to invalid personal identity info. It even had the right logo and gave a very legitimate looking case number. And of course had a 'link' to sign into my PayPal account to rectify the problem. My junk mail scanner did not catch it.
I exited my email and signed into my PayPal on a new screen just to check and of course there were not problems to rectify. But they sure are starting to look and sound professional. Too bad they keep forgetting that genuine notifications from PayPal never include a link to sign in to your account!
