My first opinion was that of Grant's because I hate getting these faxs too. You should see all the stock "inside information" faxs that come through and the like that just gets tossed in the trash. However, I've read where this has worked for some.
Before I posted this topic though, I thought of why it may work for some.
I don't like seeing the junk "stock market" faxs come through for two reasons: 1) I don't do anything with the stock market. 2) Like Grant, I pay for the ink and paper.
Most people that we would send a fax too though, are not the ones who will pay for the ink or paper. They are part of a larger company who pays for these and more then likely don't even think about the cost. Also, I will not be sending a fax to a home fax.. or to a dentist office.. only to places that I feel would be interested in our services.
If I do try this fax marketing, I will include a line on the fax that states if they do not wish to receive future faxs, to call this number. If and when they call, I will apologize and politely offer them a discount.
