In a survey of more than 800 users, Nucleus finds spam continues to be a growing problem. Despite aggressive spam filtering, 66 percent of messages getting through the filters and into users’ inboxes are categorized by those users as spam. With users spending more than 1 percent of their time tackling spam in their inboxes each day, American companies alone are losing more than $70 billion a year in lost worker productivity.
