High Quality Content by WIKIPEDIA articles! Disposable email addressing (DEA) refers to an alternative way of sharing and managing email addressing. DEA aims to set up a new, unique email address for every contact or entity, making a point-to-point connection between the sender and the recipient. Subsequently, if anyone compromises the address or utilises it in connection with any email abuse, the address-owner can easily cancel (or "dispose" of) it without affecting any other contact. Following the cancellation or replacement of a disposable emailaddress, the (ex-)owner need notify no more than one person/contact of the change.
