Washington - Postmaster General John Potter today accepted the resignation of Robert F. Bernstock as president of Mailing and Shipping Services, effective June 4.

Bernstock will pursue opportunities in the private sector.

Bernstock joined the Postal Service as president of the newly created Mailing and Shipping Services in June 2008, agreeing to work with the Postal Service for an initial period of two years.

"Bob led the effort to rethink and redesign the USPS customer experience. His talent, creativity and extensive business experience have benefitted the Postal Service, our customers and our employees," Potter said.

As president, Bernstock was responsible for all product management, product development, retail and commercial products and services, as well as commercial sales. The division is responsible for more than $65 billion in annual revenue.

Among Bernstock's achievements during his tenure at the Postal Service are:

- The Summer Sale and other groundbreaking pricing incentives that successfully generated incremental mail volume and increased revenue.
- The Priority Mail Flat Rate Box integrated marketing campaign, "A Simpler Way to Ship" that engaged employees across the country, provided consistent and unified messaging across all retail channels and led to record growth.
- A complete reimagining and revenue-focused redesign of the Postal Service website, usps.com. When complete this fall, customers will find a 21st Century system architecture that is easier to navigate, with customer-friendly interactive features making it even easier to do business with the Postal Service.
- The first Postal Service mobile applications launched earlier this year are part of ongoing efforts to channel technology for customer and business benefits.
- The first Intelligent Mail barcode (IMb) "app" that allows customers to buy greetings with postage included for one price. "Postage Paid Greetings" uses a unique IMb on each card included in a package of cards. The business customer pays the postage expense when the cards are mailed.

"Bob's work will have long-lasting, positive impact on the Postal Service and its customers," Potter said.
