Once the list is done going through the verification process, the breakdown of statuses is easy to understand. Their pricing is also very reasonable. **What do you dislike about Kickbox?** It would be helpful to know how Kickbox determines the validity of an email address. Not sure if they publish their processes on how they go about verifying an email address, but easy access to this information would help establish more of my trust in the platform. **What problems is Kickbox solving and how is that benefiting you?** Kickbox is helping us sift our email data into buckets that allows us to determine quality so that we can take appropriate action.
