Can’t send promotional products to all your customers? Start with the ones that are most likely to be evangelists for your products or services. For software companies, that might mean developers or other members of related online communities, like in the Macromedia example below, or beta testers. Microsoft recently sent out this promotional flyer to folks who beta tested Windows Live. In this case the recipient was both thankful, and posted a photo of the product on his blog, turning promotional product advertising into online advertising.
