Certified Email messages are marked with a blue ribbon envelope icon to let consumers know they come from a legitimately vetted source. The program is already in place at AOL and Yahoo.
Through Sept. 30, Goodmail is guaranteeing qualifying ecommerce senders who enroll in the program a minimum 300% ROI through increased click-through rates, conversions and revenues per email.
Coverage now extends to about 60% of consumer email users. The new partners will implement the system over the course of 2007.
