Thanks for the replies. I already signed up for both services ages ago, and that does not seem to help. I’ve also tried calling and emailing both the real estate agents and their affiliated agencies, but that doesn’t help. I believe they are using public records of home owners to send out the postcards. There are also agents who send out postcards to everyone in my building whenever a unit is for sale in the building, and again when the unit sells. I know what their motivations are, but these postcards make me dislike real estate agents even more.
