Hundreds of SPAM emails

Xfinity, what are you doing to STOP the hundreds of SPAM emails I get every single day?  They are not even addressed to me!  It is a random email address but there are literally hundreds everyday and some with the same subject.  I don't have time to block ALL of these as it would take me all day to do so.  I forward them to the SPAM folder but only hours later, I have multiple emails again NOT addressed to my comcast email address.  What is being done about this?
