Ran the CSV through our deduper first. Dedup pass only flagged 1.2% — cleanest dataset I've worked with. Bought it to map pulmonologist doctor density across India. Connect rate could have been higher with cleaner mobile numbers.
Good to know what worked and what didn't, the email/LinkedIn coverage you mentioned is on our list for the next pass. If you want the gaps fixed sooner than the next refresh, open a support ticket and we'll spin a one-off pull.
