I have only recently (Jan 2008) begun sending out a monthly postcard to my clients with a quick focus tip (for my ADD'ers) and an easy organizing tip for those folks who hope to reach organizational utopia. The response has been fantastic; I've signed on three new clients and some others are in the pipeline.
Regarding newsletters I receive from other people - I may be old school but I prefer a hard copy I can make notes on. Also, due to the large amount of email I receive, I tend to immediately delete anything that I don't need to respond to. When I am in the office I don't want to be distracted (usually) whereas if I have an extra few minutes in the car or at home I'll pick up anything and read it.
I also tend to get P.O.'d if someone adds me to their email list without my permission but don't much care about receiving something in the mail (so easy to recycle).
