What Does Disposable Email Mean?
Disposable email is a service provided to a registered user for a given period of time, using a temporary address. It should be distinguished from a disposable email address, which simply forwards messages to a primary email account and is often called an alias.
Disposable email is also known as temporary email and throw-away email.
Techopedia Explains Disposable Email
A disposable email service allows a user to register for a discussion forum and not receive spam via their primary email address. It typically has separate inbox, reply and forward functions.
Some disposable email service providers automatically create a temporary email address as soon as a potential user visits their site and clicks on a link. The user is then assigned a temporary email address, which may or may not be used.
