Email fraud (or email scam) is intentional deception for either personal gain or to damage another individual by means of 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 its 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 schemes to get rich quickly. These include '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.
Email sent from someone pretending to be someone else is known as spoofing. Spoofing may take place in a number of ways. Common to all of them is that the actual sender's name and the origin of the message are concealed or masked from the recipient. Many instances of email fraud use at least spoofing, and as most frauds are clearly criminal acts, criminals typically try to avoid easy traceability.
Phishing is a type of social engineering where an attacker sends a fraudulent (e.g., spoofed, fake, or otherwise deceptive) message designed to trick a person into revealing sensitive information to the attacker or to deploy malicious software on the victim's infrastructure such as ransomware. Some spoof messages purport to be from an existing company, perhaps one with which the intended victim already has a business relationship. The 'bait' in this instance may appear to be a message from "the fraud department" of, for example, the victim's bank, which asks the customer to: "confirm their information"; "log in to their account"; "create a new password", or similar requests. Instead of being directed to the website they trust, they are referred to an identical looking page with a different URL. After entering their log-in details, their username and password is visible to the perpetrators. In many cases, phishing emails can appear to be benign - for example, a message prompting the receiver that they have a new friend request on a social media platform. Regardless of how innocent the message is in itself, it will always lead the victim to an imitation web page and false log-in prompt.
Email solicitations to purchase goods or services may be instances of attempted fraud. The fraudulent offer typically features a popular item or service, at a drastically reduced price.
Items may be offered in advance of their actual availability. For instance, the latest video game may be offered prior to its release, but at a similar price to a normal sale. In this case, the "greed factor" is the desire to get something that nobody else has, and before everyone else can get it, rather than a reduction in price. Of course, the item is never delivered, as it was not a legitimate offer in the first place.
Such an offer may even be no more than a phishing attempt to obtain the victim's credit card information, with the intent of using the information to fraudulently obtain goods or services, paid for by the hapless victim, who may not know they were scammed until their credit card has been "used up."
Requests for help
The "request for help" type of email fraud takes this form: an email is sent requesting help in some way. However, a reward is included for this help, which acts as a "hook". The reward may be a large amount of money, a treasure, or some artifact of supposedly great value.
This type of scam has existed at least since the Renaissance, known as the "Spanish Prisoner" or "Turkish Prisoner" scam. In its original form, this scheme has the con man purport to be in correspondence with a wealthy person who has been imprisoned under a false identity and is relying on the confidence artist to raise money to secure his release. The con man tells the "mark" (victim) that he is "allowed" to supply money, for which he should expect a generous reward when the prisoner returns. The confidence artist claims to have chosen the victim for their reputation for honesty.
Business email compromise is a class of email fraud where employees with privileged access (such as to company finances) are deceived into making invalid payments or installing ransomware
Advance-fee scam: Among the variations on this type of scam, are the Nigerian Letter also called the 419 fraud, Nigerian scam, Nigerian bank scam, or Nigerian money offer. The Nigerian Senate emblem is sometimes used in this scam.
Lottery scam: The intended victim is often told their name or email address was selected through a random computer ballot and sponsored by a marketing company.

The victim is asked to contact the claims agent or award department.
FBI email: Claim to be an “official order” from the FBI’s Anti-Terrorist and Monetary Crimes Division, from an alleged FBI unit in Nigeria, confirm an inheritance, or contain a lottery notification, all informing recipients they have been named the beneficiary of millions of dollars.
Hitman: An email is sent to the victim's inbox, supposedly from a hitman who has been hired by a "close friend" of the recipient to kill him or her but will call off the hit in exchange for a large sum of money. This is usually backed up with a warning that if the victim informs local police or the FBI, the "hitman" will be forced to go through with the plan. This is less an advance-fee fraud and more outright extortion, but a reward can sometimes be offered in the form of the "hitman" offering to kill the man who ordered the original hit on the victim.
Investment schemes: Emails touting investments that promise high rates of return with little or no risk. One version seeks investors to help form an offshore bank.

Romance scam: Usually this scam begins at an online dating site, and is quickly moved to personal email, online chat room, or social media site. Under this form, fraudsters (pretended males or females) build online relationships, and after some time, they ask for money from the victims.

When a victim is engaged, they ask for communication expenses such as translations, voice phone calls, video calls, "agency fees". They impersonate the brides instead of providing a matchmaking service to them. The real ladies may not be aware that someone is using their identity.
Secret shopper: The intended victim is solicited via email to work as a 'secret shopper', often after the victim's resume has been posted at a job search site.

The scammer spots the resume and sends the victim an email claiming to be a legitimate job listing service, and claiming to have a client who is looking for an employee with their skills and experience. The victim is invited to click on a link to apply for the job. Clicking the link takes the victim to a job description specifically written for the skills and experience on the victim's resume, and provides a very high salary, and invites them to "click here" to apply for the job. If the victim clicks on that "apply" link, they are taken to an "application" form that asks for the normal job application information, PLUS the victim's social security number, date of birth, the name of the bank and account number where they will want their paycheck to be deposited to, a "relative" reference, etc. With this information, the scammer can open up a bank account in any on-line bank and utilize the victim's credit to buy items online and ship them to associates who are in on the scam.
PayPal scam: Fraudulent emails claiming the victim has been issued a payment to the his/her account, however processing will be complete once the victim has sent the item he/she is selling to the individuals address. This scam is mostly common in selling items to individuals abroad.
Avoiding email fraud
Due to the widespread use of web bugs in email, simply opening an email can potentially alert the sender that the address to which the email is sent is a valid address. This can also happen when the mail is 'reported' as spam, in some cases: if the email is forwarded for inspection, and opened, the sender will be notified in the same way as if the addressee opened it.
Email fraud may be avoided by:
Not responding to suspicious emails.
Keeping one's email address as secret as possible.
