The good news is that cleaning up old email addresses is easy, accurate and cost-effective.

Our product choices for identifying old email addresses are

CORE

If your list contains fewer than 500,000 unique email addresses you can upload it at anytime for self-serve validating. CORE provides results in extra columns on the end of yours.

In addition CORE provides information about the domain country code and mail provider; in total you receive four pieces of information about each email address.
