Ask HN: How do I get off marketing email lists from IT vendors?

I get a bunch of emails from folks trying to sell my employer stuff. I am simply not the person to be selling stuff to...

I have even received phone calls on my personal cell phone about it many times. One guy actually told me which list they use and I was able to remove myself from it. This cut down a lot of spam, but not all.

Does anyone have a collection of Opt-Out links for this kind of spam?

The one I know of is for Apollo.
