I set up an e-mail account for these type of things, but I get very little spam mail anyways. I find if you don't answer the survey type or the "get up to XXX bonus point" type e-mails I don't get spam. I generally only take the "get 5 points for visiting" the website pages. That, plus one 50 order from Lancome has put me at 5,000 in about 9 mos. Works for me.
