I have a friend online who mailed out 20 letters to people/companies with reputation issues. Before he was able to follow up with a phone call (about a week after mailing), someone called him to get more information. In a small sample, that's a 5% response rate which is fantastic. If you mail 100 letters you would get 5 calls, if you can close 1 of those, you would have a 1% closing rate on the direct mail pieces. That is an easy to scale process. What do you think?
