International examples of mail profitability are driven by multi-faceted strategies, of which pricing is one part
The USPS Office of Inspector General recently released a research report on the profitability of mail in other countries. It concluded that several smaller nations have found ways to make mail sustainable, albeit at much lower volume levels than in the past. They also have found that mail can be the leading revenue and profit generator with posts that have other business lines such as package shipping, logistics and financial services.
To try to determine the drivers of the mail profitability the OIG looked more closely at five posts–Australia Post, bpost (Belgium), Deutsche Post DHL, Swiss Post, and Royal Mail. While the study found that raising postage prices can compensate somewhat for lower volumes in these countries, they also noted several major differences with the USPS. Pricing is not a standalone solution to falling volume without employing a robust, comprehensive strategy. USPS has a long way to go to equal successful strategies elsewhere.
