Always Free to Know

You deserve to know the status of your email list at all times, without having to pay up front. Our always free report empowers you to make informed decisions on the management of your email database.

Customer Centric

As a customer, you receive a dedicated customer advocate and are guaranteed a 30-minute initial response to any support request during business hours.

Self-Service Platform

Whether you have a list of 500 or 5 million, our self-service platform allows you to upload lists of any size, at any time. You decide when to upload, review, and purchase a list. Control the entire process through your personalized dashboard.


As soon as your list is uploaded it begins processing and can be ready in as little as an hour. Once a list is complete, you can review the results, purchase the cleaned email list, and import it back into your ESP.
