An e-mail scam is a fraudulent e-mail that appears to be from a legitimate Internet address with a justifiable request — usually to verify your personal information or account details. One example would be if you received an e-mail that appears to be from your bank requesting you click a hyperlink in the e-mail and verify your online banking information. Usually there will be a repercussion stated in the e-mail for not following the link, such as "your account will be closed or suspended". The goal of the sender is for you to disclose personal and (or) account related information. This type of e-mail scam is also called phishing. (Source: Webopedia; All About Phishing)
