As I think I've mentioned before, I have four email accounts, and manage two others for clients. That's a lot of spam. Gmail and Entourage have decent spam filters, but a fair amount manages to make its way through, and every so often I look through the spam folders just to make sure I haven't missed anything important.
What surprises me is not the number of emails that are obvious scams, but how amateurish these attempts are. If you are pretending to represent a financial institution, wouldn't you take the trouble to spell its name correctly? If you're soliciting lonely men, why would you waste your time sending an email to an address that obviously belongs to a woman? And in all of these cases, if you're presenting yourself as a legitimate commercial enterprise, can't you take the time to run the email through your software's grammar and spelling checker?
The other thing I don't know is how many people respond to these spam messages. Someone must, or the spammers wouldn't bother; I wonder how many responses they need to get in order to make the effort worthwhile.
I'd think that everyone knows about the Nigerian email scam by now, but apparently not. And maybe legitimate emails have gotten so sloppy that the fake ones now look normal.
