YouMail CEO Alex Quilici said the Ohio lawsuit may have had an effect. “It’s too early to tell if overall robocall volume has been decreased by the Ohio AG action,” Quilici said. “However, the volume of car warranty calls has dropped materially since that action.” The calls coming from the operation that was the subject of the suit, he added, “have gone to zero.” It’s not clear yet whether “other calling campaigns that have been increasing will offset this,” he added. “There are so many other robocall campaigns at scale going on all the time.”
