Verification is our service where we determine which email addresses will not be delivered and hard bounce right back to the sender. Hard Bounces are the second most harmful type of email data, eliminating these emails from a list is vital to a successful campaign. CleanMyEmails is able to verify Yahoo email addresses utilizing trade secret and proprietary technology. In addition to all of the popular domains such as Gmail, AOL, and Outlook, our verification service is also able to work with B2B domains making use of a specially developed grey listing technology.
We use sophisticated technology and dedicated IP addresses to check mailboxes and determine whether messages will soft bounce, hard bounce or deliver.
