How do I find someone's email address when it isn't public?

A starting point

Start with the obvious: their site, LinkedIn contact info, or a plain guess at the company's email pattern (first@, first.last@), then verify before sending so you don't burn deliverability on bounces. Email-finder tools help, but treat their output as a guess, not a fact, and always run it through a verifier. As a starting point, if you can only find a generic info@ address, a warm reply on LinkedIn or a real intro usually beats guessing an inbox that may not exist.

Why we picked it This is the plain, do-it-yourself walkthrough to read before you pay for any tool. It covers the free manual routes (guessing the company email pattern, Google search operators, LinkedIn contact info, the GitHub commit trick) alongside the finder and verifier tools, with rough accuracy and effort noted for each. It also drills the one rule beginners skip: always verify before you send, because a bounce costs more than the address was worth.

How to Find Anyone's Email Address: 13 Methods That Work

From saleshandy.com by Saleshandy

  • Most companies use one predictable email format, so one known address at a firm often unlocks everyone else's.
  • Free methods (Google operators, LinkedIn, GitHub, company pages) get you far before any paid finder is needed.
  • Every method ends the same way: verify the address first, because bounces damage your ability to reach anyone later.

Why we picked it A guessed or bulk-sourced address is a gamble, and one bounce-heavy send tells Gmail and Outlook you are not a real sender, which follows your domain for weeks. Run each address through ZeroBounce first: it flags invalid addresses, spam traps, and catch-all domains before you hit send. Think of it as the safety step between finding an email and actually mailing a founder you want to keep as a contact.
