So are there any mistakes that you should avoid making or making again. It is also the quickest way to turn strangers and potential customers into enemies. You may have made the leap that when I speak of crop dusting, I'm talking about blindly using direct marketing. These are direct mail, bulk faxing and spamming. Each one climbs up one rung on the offensive ladder.
Direct mail is really only as effective as the list itself.
If they have no interest in the product, don't have money for the product or hate direct mail in general, your sunk. Bulk faxing should only be done with the prospects approval. If you batch send out a bunch of faxes, you are eating up the prospects paper, toner and perhaps more important connection time. Spam emailing is probably the worst. It costs almost nothing to do and can be sent out to a very broad audience.
