Phishing URL checker addresses (DEA) are temporary email addresses that users use for one-off communications or to access content without revealing their real email address. Users can often generate these email addresses in just a few clicks, and they self-destruct after a short period of time—for example, within twenty minutes. This makes it easy for consumers to sign up for mailing lists and leave one-off comments on blog posts without exposing their real emails to bad actors or losing the benefits of the service.

Unfortunately for marketers, this can negatively impact deliverability and skew analytics. It can also make it difficult to connect with the audience, and it may lead to a high bounce rate or a lower sender reputation.
