Depending on what type of e-mail service you are using, some have options to identify e-mails from sources as spam and they will either be discarded or sent to a spam folder where they can be easily discarded.
Also, on some spam, you may be able to have your name removed from distribution. Sometimes there is a note at the bottom to request to be removed.
Haven't seen what you are looking at so I don't know for sure but thought I would try to help.
Good luck.
