Postmaster Network is an online marketing company that exploits the email niche, by putting together all the actors that have a saying in email/newsletter branding and advertising campaigns. What users will be able to learn about when visiting this site is divided into the different kinds of clients whose needs this firm caters for: publishers and site owners, brokers, advertising agencies and marketers themselves.
Each section explains briefly but in detail the services and products Postmaster Network offers, and in some cases provides calculators and scenario planners to try and help the prospective clients determine which kind of approach they should favor. Also interesting about this site is that it presents lots of useful and concrete articles on marketing techniques and tactics, which in turn will make the site attractive not only for the company’s potential clients but for other marketing-related audiences. The only problem I found to Returnpath.net/postmaster is that since they promise to be so revolutionary in terms of practices and approaches, it is a bit hard to grasp exactly what they do; although it could be considered a bit old-fashioned, having a sample of their products for clients to see seems to me like a good marketing technique.
