Ran the CSV through our deduper first. The phone column was live for 95% of the rows I tested. Bought it while building a neurosurgeon doctor prospecting workflow for United States. Genuinely useful.
Pulled the trigger after reading the row count. Catchment overlap with our existing CRM was minimal — almost all net-new leads. Bought it to map neurosurgeon doctor density across United States. Money well spent.
Tried three vendors before this. Bounce rate stayed under 4% on a 1,000-contact email send. Bought it for a United States-focused neurosurgeon doctor territory cut. Saved us hours of manual cleanup.
