Does anybody know of a site that provides contact info for REO departments?

I am looking to do a mass mailing to lenders, specifically REO departments. In leiu of going and finding contact info for each individual bank, is there a list of some sort that will expedite this process? has the websites, but I suspect you’re looking for the physical mailing addresses.

yes, I have been to that website, and while it does provide current listings of REO properties, I am looking for numbers and addresses of the departments for each major lender.
