What is a Disposable Email Address?

Disposable email addresses are temporary email address accounts that can be quickly created or discarded. They are used for very short periods of time and allow users to bypass certain restrictions online where an email address is required. Temporary addresses are frequently used by low quality users and cybercriminals, so it's a good practice to prevent these kinds of email addresses.

Temporary and disposable email providers are gaining in popularity, as mail services have made it easier for users to create their own disposable email service. These types of emails are considered low quality since users typically only use them for a few minutes to create fake accounts or bypass some form of user validation. These inboxes are often never checked again. Users typically create many disposable emails within a short period of time. Most temporary email services will allow the user to create an unlimited amount of accounts, which is why detecting disposable emails is so important for any website or business online.
