Not everyone is able to simply ignore and delete spam according to a new study discussed in a USA Today article. The study found that 20% of Americans have purchased something from a spam email and 1/3 said they have responded to spam emails. The study did not go into what type of emails the people consider spam, so it is possible the people surveyed could have been responding to emails from merchants they had ordered from previously or simply responding to other subscription content that was not actually spam. At any rate, the fact that some people do respond to spam emails is probably the main reason the spammers keep sending it.
