Abstract:

If you think post cards are for nothing more than 'wish you were here' messages, think again. Post cards are serious tools for building relationships with customers--tiny billboards with big missions. They are one of those often-used but little analyzed marketing mediums--a perfect platform for some 'jolt thinking.' Jolt thinking questions the basic premise--the what, why, and how of doing something. How? By answering three questions. What is the purpose? Why is it done the way it's done? And how can I do it most effectively?
