Ran the CSV through our deduper first. Email coverage is the highest I've seen for United States B2B data. Bought it for a United States marketing agencie market-sizing project. Couple of small gaps but workable.
Plugged it straight into our outreach tooling. Encoded UTF-8 with no character-set surprises in Excel. Bought it as part of a wider marketing agencie expansion into United States. Will buy again.
