Disposable inbox prevention an era where digital privacy is constantly under threat, disposable email addresses are a useful tool for individuals looking to protect their inboxes and minimize the risks associated with spam, hacking, and data breaches. Disposable emails, which range from temporary addresses that only receive incoming emails for a set amount of time to masked and alias emails that forward messages indefinitely, serve as a barrier between an individual’s primary inbox and the websites or services they sign up for.

One of the primary reasons that users create disposable emails is to reduce the likelihood of their personal inboxes becoming clogged with unwanted communications, as a result of the sites they sign up for selling their email addresses for marketing purposes. They are also commonly used by people who wish to avoid getting their real email address caught up in a data breach and/or account takeover (ATO), where attackers replace the original user’s legitimate email with a fake one in order to access the platform’s assets, such as in-game items or virtual currency.

As a website operator, you must be mindful of the ways in which individuals use disposable email addresses, as they are often employed by low quality users, bots, and cybercriminals. Disposable inbox prevention begins with identifying these users during the registration process, and includes tracking suspicious patterns of behavior that can be indicative of low-quality accounts, such as quickly creating multiple accounts or signing up from different IP addresses. Moreover, implementing an MX record check during the signup process and maintaining a domain blacklist of known disposable email providers that are known to provide spam and abuse will help in preventing these types of accounts from entering your platform.
