You probably still get a bunch of bulk emails, simply because it's a pain scrolling around to find the elusive "Unsubscribe" link. Gmail just solved that: now, an unsubscribe option pops up right next to the sender's address in certain types of mail. Scroll no more.
Whether you willingly signed up in the naive hope that maybe this one would prove useful, or your email address just magically appeared on the list, chances are your email inbox is plagued by an onslaught of undesirable newsletters on the daily. So it takes a lot to make it into the most-hated list.
