How to Find Someone's Email Address (10 Ways)
From email finder tools to pattern-matching and verification, here's how to find almost anyone's work email address — and confirm it's real before you send.
Overview
Finding a work email address is usually fast once you know the methods: a dedicated email finder, a company's known address pattern, or the person's own public footprint. The part people skip — and the part that actually matters — is verification. Sending to guessed or stale addresses drives bounces, and a high bounce rate is one of the quickest ways to wreck your sender reputation.
10 ways to find an email address, fastest first
Work down this list until you have a candidate, then verify it. The first three get you there most of the time:
1. Email finder tool — Hunter, Apollo, or Snov.io take a name + company domain and return a likely address with a confidence score. Fastest at scale.
2. The company email pattern — find one known colleague's address (a team page, a press release, an email they sent) and copy the format. "jane.doe@acme.com" means everyone is first.last@, so you can build your target's address. See company email address format.
3. LinkedIn + a finder extension — pull the name and company straight from the profile; see how to find email addresses on LinkedIn.
4. Their personal site or about page. 5. GitHub profile (often a public commit email). 6. A conference talk, podcast, or speaker bio. 7. The reply-to on a newsletter they send. 8. The company contact / press / about page (or a press@ alias). 9. Twitter/X bio or a linked Linktree. 10. A mutual connection who can introduce you — the warmest option of all. Common patterns to test: first.last@, first@, flast@, firstl@, last@.
- Email finder tools (Hunter, Apollo, Snov.io) with confidence scores
- Company email pattern from one known colleague
- LinkedIn + a finder's Chrome extension
- Personal site, GitHub, conference/podcast bio
- Newsletter reply-to; company contact/press page
- A mutual connection (warmest of all)
Always verify before you send
A found address is a guess until it's verified. Run candidates through an email verification service to catch typos, dead mailboxes, disposable domains, and catch-all domains before they become bounces. Most finder tools include a confidence score; treat anything below ~90% as unverified and confirm it separately. Why it matters: mailbox providers read a high bounce rate as a spam signal, so sending to unverified guesses doesn't just waste effort — it lowers inbox placement for your good addresses too.
Respect the legal and ethical line. Finding a business email for relevant B2B outreach is normal and legal in many regions if you follow opt-out rules like CAN-SPAM and privacy laws like GDPR; scraping personal addresses, harvesting at scale, or ignoring unsubscribes is not. Stick to work addresses, keep a suppression list, and honor every opt-out — Mailbase enforces suppression at send time so a bounced or opted-out address never gets re-mailed.
- Verify every candidate before it touches a send
- Treat confidence scores below ~90% as unconfirmed
- Catch-all domains accept everything — they can't be confirmed by acceptance alone
- Business addresses only; keep a suppression list and honor opt-outs
Common Mistakes
- Sending to found addresses without verifying them first.
- Treating a finder's confidence score as a guarantee.
- Guessing a pattern on a catch-all domain and assuming it lands.
- Harvesting personal addresses instead of business ones for B2B outreach.

FAQ
What's the easiest way to find someone's email address?
An email finder tool — Hunter, Apollo, or Snov.io — that takes a name and company domain and returns a likely address with a confidence score. If you don't have one, work out the company's email pattern (first.last@, flast@) from one known colleague's address and apply it to your target.
How can I find an email address for free?
Find one known address at the company and copy its pattern; check the person's GitHub, personal site, or newsletter reply-to; or use the free tier of a finder like Hunter. Whatever the method, verify the result before sending — free guesses still cause reputation-damaging bounces.
Are email finder tools accurate?
The good ones are reasonably accurate and give a confidence score, but none are perfect and data decays as people change jobs. Always verify a found address before adding it to a send, because high bounce rates damage your sender reputation.
Is it legal to find and email someone's work address?
B2B outreach to business addresses is legal in many regions if you follow rules like CAN-SPAM (truthful headers, a physical address, a working opt-out). Personal-data and consent laws such as GDPR add requirements, so check your and your recipients' jurisdictions, and never harvest personal addresses.
