Identify disposable emails and prevent fake sign-ups

Many online retailers require a valid email address in order to make a purchase or access content. Unfortunately, some people take advantage of this requirement to create disposable email addresses in order to repeatedly access free trial offers, discounts and introductory bonuses. Unfortunately for marketers, this kind of abuse distorts the results of campaigns that rely on data to make informed decisions about customer conversion and engagement.

 

Identify disposable emails and prevent fake sign-ups email services – often referred to as burner email, one-off, auto-destruct or throwaway emails – offer a variety of features that allow users to quickly and easily create an email address for one-time use only. These temporary email addresses often look like real ones, and the user can quickly disable them at any time. Alternatively, they can be canceled by the service provider at any time to prevent them from being used for fraudulent activities.

While it is impossible to stop everyone from using disposable email addresses, there are a number of ways you can reduce the impact of such addresses on your marketing efforts. These methods include building trust with subscribers through respect and authenticity, providing relevant and valuable content, offering appropriate products/services and optimizing the subscriber journey.

 

Identifying and removing these zero-value addresses from your database is essential to ensure you are only sending emails to warm subscribers. To do this, you can use a real-time email validation service to flag these one-off addresses upon collection (Kickbox, for example) or restrict their entry into your list altogether by connecting an email verification API.
