List approval is our process to verify the existence of contacts in your list. In simpler terms, we make sure they are valid emails. During the list approval process “Under Review,” we sample a small percentage of your list using a 3rd party such as BriteVerify and Kickbox.
If the list has a high percentage of Invalid, Accept All or Unknown emails the list will be rejected.
However, in most cases, the list is approved within a matter of minutes depending on the size of the list. If your list is not approved, you will be notified via email with instructions on steps to get it approved.
