About MailPattern
MailPattern is a B2B email finder and verification tool. Given a contact's name and company domain, it identifies the company's email pattern from a dataset of 2.2M verified patterns across 1.68M domains, generates the address, and shows a confidence score. When there isn't enough data, it says so instead of guessing. Single lookups on the homepage are unlimited and free, with no sign-up required, and include mail-server verification (Valid, Invalid, Risky, or Catch-all). A Chrome extension adds the same lookup to LinkedIn profiles, and a bulk tool processes CSV lists — free accounts get 200 rows per month. Paid plans are one-time payments (1, 3, 6, or 12 months of 500–1,200 verified rows/month) rather than subscriptions, with no auto-renewal.
