Be warned, one reader (and AU) reported a spam email he just got from American Express Service Online <firstname.lastname@example.org>
He was smart and called the number on the back of his card and they verified it was spam. A real email would have his full name and last four of his card. Also the email comes from a made up domain. The verify link is an attempt to gather personal information!
Be aware of this scam and don’t fall for it!
