POSTALWORKS was a Permission based email campaign service that provided advertisers the ability to market to willing “volunteers” who would opt in on receiving email promotions. Each email campaign would be tailor made to be personal and relevant to the recipients, guaranteeing that consumers would pay more attention to the marketing message, and encouraging participation in a long-term, relevant interactive marketing campaign. With a full suite of highly scalable application modules and distribution architecture, PostalWorks offered clients a robust set of proprietary tools and an intuitive interface designed for the management and distribution of “smart” email marketing messages, and dynamic publications over the Internet. Beyond just targeting individuals with personalized and relevant email, PostalWorks could track a campaign’s response/usage of recipient users, including both the immediate response and the chain of future responses, based on whether the recipient ever actually opened their email.
