Disposable Email AddressDisposable email addressing (DEA) is the name of an alternative way to share and manage email addresses. The idea behind DEA is to create a new, unique email address for every contact or recipient. This makes a point-to-point connection between the sender and the recipient. Subsequently, if the address is compromised or abused in any way, it can be easily cancelled (or "disposed") without affecting any other contact. If an address is cancelled or replaced, no more than one person/contact has to be notified of the change. By comparison, the traditional practice of giving the same email address to multiple recipients means that if that address is subsequently cancelled, many legitimate recipients will have to be notitified of the change and their records updated - a potentially tedious process. The key element with DEA is that a different, unique disposable email address is created for every recipient, and that it is shared only once. Most likely, but not always, a DEA is cancelled because the email address is being used in an illegitimate manner. This may occur because an email was accidentally relased to a spam list, or because the recipient was purposely deceptive and unscrupulous. Whatever the cause, DEA allows the user to take unilateral action by simply cancelling the address in question. Later, the user can determine whether to update the recipient or not. For convenience sake, disposable email addresses typically forward to one or more real email mailboxes where the messages are received. The recipient of a DEA never needs to know the real email address of the user. If the DEA is managed in a database, it is also possible to quickly identify the expected sender of each message by retrieving the recipient of each unique DEA. Used properly, DEA can also help identify which recipients are handling email addresses in a careless or illegitimate manner. Moreover, it can be an effective tool for spotting counterfeit messages, or phishers. DEA is most useful in situations where you suspect the email may be sold or released to spam lists or other unscrupulous entities. The most common situations are online registrations for things like discussion groups, bulletin boards, chat rooms, online shopping, and download websites. At a time when email spam is an everyday nuisance, and identity theft is a real danger, DEA can be a convienient tool for keeping someone safe and sane.
