It still amazes me how many of these fake emails there are.
There have been one or two occasions where I "almost" fell for it. The easiest way to see if it is fake is 1. check the return email and 2. on the click on the link hover over the link but don't click on it and see where it is taking you.
Bottom line is if in doubt, call first and never open an attachment that you don't know 100% who sent it to you.
I love the ones that are from banks that I have no account.
