I have a 150.000 USA email list with people that are looking to rent a house or an appartment. I did work for a big rental company and these people contacted me by email in the last 2+ years, the list is 80% active and I`m wondering how can I monetize it. If you would have it, how you would promote it? Appreciate all the answers! Edit : I did sent a email to 10.000 persons if they are still looking for a house and aproximate 70% responded back that they still looking and the rest of %30 that they already found one.
