How to keep leads off of your list

[John Horner]

I have been doing mailers for just over a year and I always get the "take me off your list" calls.  I always do take them off my list, but now I am getting to the point where I need to refresh my lists.  How do other marketers deal with this.  Do you keep all of the "Take me offs" and when you refresh your list you manually go in and take them all off?

Even with the standard yellow format postcards I get threats to sue me.  Now I don't think they could or would sue me but I don't want to intentionally upset anymore people.
