BTW, how is it considered "junk" mail if they are giving you an offer to improve your life? 
unsolicited advertising mail is often considered "direct marketing" by the senders and "junk mail" by the recipients, "junk" because >95% goes straight in the bin (trash)
eta: in NL we can put a legally binding sticker on our letterbox indicating "yes or no" for two levels of unsolicited mail (roughly equating to advertising blah and local newspapers)
