What is Email Fraud?

Legal Definition
Email fraud is the intentional deception made for personal gain or to damage another individual through email. Almost as soon as email became widely used, it began to be used as a means to defraud people. Email fraud can take the form of a "con game" or scam. Confidence tricks tend to exploit the inherent greed and dishonesty of their victims. The prospect of a 'bargain' or 'something for nothing' can be very tempting. Email fraud, as with other 'bunco schemes' usually targets naive individuals who put their confidence in get-rich-quick schemes such as 'too good to be true' investments or offers to sell popular items at 'impossibly low' prices. Many people have lost their life savings due to fraud.
