I sell a product to businesses through direct mail. I want to try opt-in email marketing but I have two problems:
a) The companies I have spoken to want a minimum order of $2000 which is more than I want to pay just to test.
b) With the number of impressions I get (250,000) for $2000, if a get even a small fraction of a 1% response I will have trouble with fullfillment.

Does anyone know of an email marketing company with smaller minimums?

Thanks in advance,
Bill Martin
