Disposable Email Detection API is essential to building a quality list of valid, engaged addresses. However, many marketers are finding that disposable emails—or at least address services that provide throwaway inboxes—are making it their way onto their lists. This can really hurt a merchant’s efforts to drive engagement.

For example, if you send an email blast to a list that contains DEAs, chances are that those addresses will bounce or be marked as spam, leading to your campaigns being lost in the noise. And if you’re looking to build brand trust and loyalty, it doesn’t make sense to spend your marketing dollars on messages that aren’t going to reach an audience.

How to Block Fake Disposable Email Addresses

In addition to being a nuisance for marketers, DEAs can be dangerous for consumers too. They can be used by fraudsters to commit online scams and to evade security measures designed to protect real email addresses. And when it comes to preventing fraudulent transactions, prevention is definitely the best medicine.

So what can you do to block fake disposable email addresses from entering your subscriber list? It’s important to identify them in real-time, at the point that users sign up for your mailing lists. This can be done by integrating an email verification API into your website registration form. This type of tool will scan the provided email address for signs that it is a DEA, and it can even identify if an email address has been used by a user before. This helps prevent DEAs from being added to your list and bogging down your deliverability.
