"Mail is what we process, transport, and deliver, but as the dominance of business mail demonstrates, the Postal Service is in the advertising business." [emphasis from original]
"The Postal Service could do so much more to actively encourage citizens and business owners to use the USPS Web site to create customized messages for delivery by the Postal Service. Invitations to weddings or birthday parties; announcements of new business ventures; promotions of products and services — the possibilities are endless, constrained only by the imagination. Why isn’t the USPS advancing this concept rather than relying so heavily on messages developed by others?
We must use advertising as a tool that generates mail. The USPS has the potential to become a full-fledged advertising giant that, with extensive use of electronic media, creates volume."
