Case Study: Poshmark achieves simplified, affordable nationwide fashion shipping with Endicia's PoshPost

Endicia Helps Poshmark Open Up Closets Across America

Poshmark is a mobile marketplace that lets users “shop each other’s closets,” rapidly growing to hundreds of thousands of active seller closets and millions of items listed. To maintain its core promise of simplicity, Poshmark needed a shipping solution that let sellers fulfill orders quickly without extra software or complicated forms — offering reliable technology, affordable carrier rates and tracking.

Endicia provided an API that generates pre-paid, pre-addressed labels Poshmark can email to sellers, and, after analyzing more than 25,000 mail samples with the USPS, helped create PoshPost: a negotiated service that ships fashion up to 5 lb anywhere in the U.S. for a $4.99 flat rate (about 28% savings). The result was instant adoption, faster fulfillment, predictable costs and fewer friction points for buyers and sellers, helping Poshmark scale its peer-to-peer fashion marketplace.
