Promotional products company ePromos says its swag work for Earthlink helped the internet service provider slash a staggering new hire churn rate.

To help Earthlink welcome new hires, ePromos produced a welcome kit in the company's orange logo color that included a letter from Earthlink's CEO and a logoed water bottle, baseball cap, mousepad and drawstring backpack. ePromos' director of marketing, Mark Yokoyama, reports that the swag resulted in a reduction in employee turnover of 50 percent.
