Email remains a critical component of successful marketing strategies, connecting businesses to a dedicated audience. How to detect disposable emails? – or burner addresses – however, can pollute lists and negatively impact campaign metrics.
Domain Reputation Guidelines: Navigating the Landscape of Trust
DEAs are temporary, single-use email addresses that auto-destruct after a set amount of time, usually within minutes. They are commonly used to circumvent email validation on web forms, signups and forums or to stay anonymous online. They are also popular among people trying to avoid spamming brands or other users of online services.
While some people use DEAs for legitimate reasons, such as to test email workflows, others will signup with them for your newsletter or free trial using a DEA, then delete the address and never come back. This type of churn can cause you to lose valuable leads and revenue.
The good news is, catching these types of one-off or throwaway emails is fairly straightforward with the help of email verification tools. Whether you’re using an API that can be integrated into your signup process or a web-based email validation tool, the right verification tools will help identify and flag disposable or alias addresses for your review.
Email verification tools will compare the domain part of an email address against a database of known DEA providers, identifying if it is indeed a disposable or alias email address. This will prevent DEAs from being included in your mailing list and help ensure that your emails are sent to engaged subscribers.
