Email Validation & Hygiene

Clean emails through a validation process that combines both email hygiene and real-time email verification.

Improve deliverability by validating email addresses

EmailOversight provides the most advanced process to clean emails through a proprietary multi-method validation process that combines both email hygiene and real-time email verification.

How we verify emails

EmailOversight uses a multi-method solution that utilizes hygiene and verification scans to identify email-based threats such as spam traps, hard bounces, complainers, bots and more. These nefarious emails will cause your sending reputation, IP/domain reputation, and overall delivery to suffer severe damage.

During the combination of scans, the email passes through hygiene, first, in order to remove the reputation and network based problems. Harmful emails like traps, litigators, complainers, bots, disposable technology, and dormant accounts are found and removed prior to moving to phase two. In our second scan, emails are then processed in our verification portion where the system connects with a real-time “PING” in order to receive a proper response code back determining the validity of each email address. Delivery based problems like hard bounces, mal-formatted emails, over-quota accounts, and syntax errors will be found and removed, thus completing the validation process. By finding and removing all the damaging email addresses through the mixture of both processes, it will immediately improve your email deliverability, reputation, and increase your overall engagement propensity.
