An advance-fee scam is a form of fraud and is one of the most common types of confidence tricks. The scam typically involves promising the victim a significant share of a large sum of money, in return for a small up-front payment, which the fraudster claims will be used to obtain the large sum. If a victim makes the payment, the fraudster either invents a series of further fees for the victim to pay or simply disappears.

Electronic mail is a method of transmitting and receiving messages using electronic devices. It was conceived in the late–20th century as the digital version of, or counterpart to, mail.
