Try using the filters, it works alot, In order to control it, you have to be active with it, and spend some time on it every now and then, I have soo many filters it's not even funny, but you know what, I don't get any spam, because I it's filtered to automatically be trashed, and I only get the emails that I really want. Plus don't forget to make sure you're not opening those spam emails, because in those emails there's a 1X1 pixel, unseen to the eye that sends a message back to the servers or spammers that that is an active email. So go ahead and try to set your filters, you'll begin to see that it actually works. Good luck.
