STAMPS.COM ANNOUNCES USPS SHIPPING INTEGRATION WITH ETSY API

Etsy sellers will have access to all USPS® mail classes including First Class Mail International™

LOS ANGELES – December 5, 2011 – Stamps.com® (Nasdaq:STMP), the leading provider of USPS postage online and shipping software to over 400,000 customers, today announced its new USPS shipping integration with the Etsy Application Programming Interface (API), allowing Etsy sellers to easily print shipping labels for all USPS mail classes, including international classes.

With the new integration, the Stamps.com software will retrieve order data directly from an Etsy seller’s account, eliminating any need to copy and paste data. Once a label has been printed, Stamps.com will automatically post order status details — delivery confirmation number, shipping date and mail class — back to the seller’s Etsy account.

Using Stamps.com, Etsy sellers can utilize time-saving features such as automated customs forms, an integrated USB digital scale, a tool to schedule free USPS package pickups, and the ability to print First-Class Mail International. Additionally, Etsy sellers now have money-saving features like postage discounts for both domestic and international shipments as well as discounted package insurance.

“Etsy has a large, growing community of online sellers and buyers who can save time and money with Stamps.com’s award-winning services,” said President and CEO Ken McBride. “Etsy sellers will benefit from the powerful e-commerce features and easy access to the competitive services of the USPS, while Etsy buyers will benefit from the speed and reliability of the USPS delivery system. It’s a win-win.”

In conjunction with the API integration launch, and for a limited time, Stamps.com will offer free service to Etsy sellers who sign up through a unique web page: http://sdcmainprod.wpengine.com/etsy10/ Sellers who sign up during the limited-time promotion and use the new Etsy integration to print their shipping labels will get three months of free Stamps.com service.
