Experian Data Quality offers an email verification solution that instantly identifies whether an email address is valid and deliverable. With industry-leading technology and unparalleled speed and accuracy, you know whether an email address is accurate and actionable before mailing to it.

Our solution works by performing multiple checks on the syntax, domain, mail server and account. All validation occurs in real time, meaning no database lookups. This email verification process can be done at the point of collection or in bulk on an ad hoc basis.
