Mmm, maybe. I'm certainly not immune to being fooled. I am careful, however. I roll over and check any link in an email before I click it, and I know when I am or am not authenticated into one of my google accounts. It's all too easy, though, to make a mistake like this when you're in a hurry or don't give something enough thought. The email was very good but after reading it a couple of times the language strikes me as not _quite_ right, especially the "unless you fix it" part at the end. Perhaps the key insight is that you have to assume going in that any email you get like this is fake, and then prove otherwise.
