Email abuse is the unsolicited sending of spam, third party advertisements, derogatory language, slander, and threats via electronic mail.
According to a 2005 YouGov/Clearswift white paper poll of 2,000 email users: 36% of users polled had received racist and/or sexually explicit material from co-workers, 23% had used inappropriate language in an email, 49% don't know their company's email use policy, and of those who do know their company's policy, 27% admit to breaking it.[1]
