Our New Catch All Email Verification Service

Traditional verification methods can not verify catch-all domains. That’s why we have developed our own catch-all service (CAV). Utilising a combination of traditional verification and email technologies, we have built a system to verify the deliverability of catch-all domains.

CATCH ALL EMAIL VERIFICATION

Our CAV solution is designed to work in conjunction with our industry leading B2B batch API so when a file is sent for validation, we will carry out the traditional verification check and the results will come back as OK, Bad and Unknown (along with the relevant additional statuses), then the catch-alls from the Unknowns will then be sent off for the second enhanced clean automatically and a second results file for this will be returned to you with the following:

StatusAdditional StatusExplanation
CatchallPassNoBounceReceivedNo Bounce Received means we have received confirmation that an email has been delivered and we received no soft or hard bounces messages from the target mail server
CatchallFailHardBounceHard Bounce means we have received a definitive response from the target mail server, such as “Email Address Does Not Exist” These emails are BAD. We recommend that you do not email to these addresses
CatchallFailBadSyntaxThe syntax of the email address has been pre-screened and determined to be badly formatted or not confirming to RFC
CatchallUnknownSoftBounceSoft Bounce means the target mail server has strict anti-spam techniques in place and refused to allow a connection. These emails are potentially OK, but should be treated with caution! We recommend you introduce them gradually into your mailing list
CatchAllRiskyInconsistentBounceInconsistent Bounce means we have received multiple responses from the target mail server. These emails are potentially OK, but should be treated with caution! We recommend you introduce them gradually into your mailing list

We Can Verify Office 365

WE ARE THE ONLY PROVIDER

Office 365 mail servers are mostly catch-all, therefore unverifiable by other services. However, the Email Checker CAV system is optimized to fully verify Office 365 emails. We are the only provider able to do this.

A TRUE CATCH ALL SERVICE

Furthermore, some Office 365 servers are not catch-all but respond with false “OKs” for emails that are in fact invalid. Our CAV system double checks all Office 365 OKs to make sure they are truly valid.
