The snail mail version.
Do any companies still use this form of marketing?

I have cut down on my advertising budget in terms of advertising in the print media, I just found that it seems to be getting more expensive and the results are the same.
I then found an old(10years) book on direct marketing and started thinking that this is a marketing practice that might return better results.
The core of my sales are to property owners and a letter in the mail might be a welcome change.
Do any forumites use this form of marketing and how do you find the return?

Another question, why is D marketing not considered spam?
