MX Guard is a list verification and scoring infrastructure by VerifiedEmail. For sales inquiries please contact sales@verified.email.

Postmasters: VerifiedEmail verifies email lists and individual emails at the point of entry by attempting RCPT TO and gracefully closing the connection after SMTP response. Prior to the delivery verification, VerifiedEmail scores addresses by identifying if a host is a disposable email address provider, is reachable, and other factors.

To avoid abuse, VerifiedEmail does not offer list washing or spam trap removal services and employs multiple layers of protection from namespace mining powered by machine learning and statistical anomaly analysis.

VerifiedEmail is a subsidiary of Clean Email, a mailbox cleaning and unsubscribing tool. Clean Email has been in business for over 10 years and has served more than 1,500,000 users.
