We just purchased the Email Verifier and have run over 26K email addresses. The initial run produced 6500 good, 600 bad and ~18K untested/with errors. We then decided to rerun the bad and untested/with errors and resulted in 2200 good, 1220 bad and the rest untested/with errors. First question is: what does "untested" mean and secondly, do we have to rerun all the time to get more accurate results? Thanks.
