Email finder and verifier for sales, recruiting, and outreach teams that need accurate professional contact data.
Hunter.io is a long-running email discovery and outreach platform built around a simple promise: give it a company domain, and it returns the verified professional email addresses associated with that company, along with the names, job titles, and source URLs where each address was found on the public web. The platform has grown from a niche email-lookup utility into a full cold outreach stack used by more than six million professionals across sales, recruiting, partnerships, journalism, and link building.
At the core of the product is the Domain Search, which crawls publicly available web pages and uses pattern-based prediction to surface every email associated with a given organization, ranked by confidence score. The Email Finder takes a person's name plus a company and returns the most likely address using the company's detected pattern (first.last, firstletter+last, etc.) validated against Hunter's 100M+ email database. A companion Email Verifier checks any address for deliverability through syntax validation, domain checks, and mail server testing — useful for cleaning imported lists before sending.
