MailPattern - Free Email Finder

Instantly guess anyone's work email from their company domain. Free, unlimited, no strings attached.

MailPattern instantly guesses anyone's work email from their company domain — completely free, with no usage limits or hidden paywalls. How it works: Type a company name or domain, or click "Pick company"/"Pick name" to grab it directly from the page you're viewing (LinkedIn, a company site, anywhere) Enter the person's first and last name (auto-filled when picked) Get a guessed email address with a confidence score based on real pattern frequency data Unlike other tools that gate results behind monthly credit limits, MailPattern's core lookup is free and unlimited. We built this because researchers and small teams deserve access to good email-finding tools without the paywalls. Features: ✓ Docked side panel — stays open alongside the page you're browsing, so you never lose your results by clicking away ✓ Pick company or name directly from any page with one click — no manual copy-paste ✓ Instant pattern-based email guessing ✓ Confidence scoring so you know how reliable a result is ✓ One-click copy for guessed emails ✓ Optional email verification (checks if an address is likely deliverable) ✓ Works with any company — search by name or domain directly ✓ No sign-up required to use the extension Need to look up hundreds of contacts at once? Visit mailpattern.tech for bulk lookup and custom lead list requests. Privacy: The extension only reads page content when you explicitly click "Pick company" or "Pick name," and only the specific text you click on — nothing is scraped automatically or in the background. We don't store your searches long-term or sell your data. See our privacy policy for details.
