“Great for Address Validation”

Easy to use and really fast! We bought the USPS Address Validation edition as we need to regular check and validate addresses in bulk. Initially we were getting about 72% hit rate which was about the same as the previous vendor, but when we mentioned this to our account manager she instantly setup a demo and showed us some things to help improve this. We then re-ran the process and it went from 72% to 91%, which then enabled us to contact over 65k new prospects, brilliant!
