After paying a lot for the shirts with the big ad on the sleeve that I don’t want to wear, I got daily emails soliciting reviews. Your ideal customer is moderately to very successful, meaning everyone is trying to get a piece of them all day every day. The people that sell the sales email programs of course peddle their own wisdom but a more important question is- do you want to sell someone a fun shirt and be an escape from all that or a nagging contributor to it?
