People and email addresses Hunter knows at a company, with roles and confidence. DELIVERABILITY WARNING: this is a directory listing, not a verified list — each row's `verification.status` is null unless Hunter has checked that mailbox, and `confidence` below ~50 is a pattern guess. Live 2026-09-08, a team that mailed generic rows (info@, sales@) straight from this endpoint bounced on 73 of 79; a hunter.people.email.verify call per address ($0.012, or leadmagic.people.email.verify at $0.006) would have caught all 73. Verify before outreach, and never invent info@ for a domain this returned nothing for.
