MailPattern

0 reviews

MailPattern is an email lookup tool that identifies professional email addresses from a dataset of 2.2 million real email patterns across 1.68 million company domains. Given a person's name and company domain, it finds the company's email pattern and shows a transparent confidence score — indicating low confidence instead of guessing when data is insufficient. Single lookups on the homepage are unlimited and free, with no registration or credit card required. A bulk lookup tool processes CSV files (free accounts get 200 rows per month), and paid plans verify each address against the real mail server via MillionVerifier, returning Valid, Invalid, Risky, or Catch-all statuses. A Chrome extension adds the same lookup to LinkedIn profiles and company websites. GDPR compliance is maintained by not storing searched emails.
