How to Find Someone's Email Address
For a work address, find the company's email format (often firstname.lastname@company.com) from any address published on its site, press releases or filings, then apply it to the person's name. For a personal address, check their website, social profiles and any public CV. If you can't find it, message them on LinkedIn or through their employer instead of guessing.
Free methods, step by step
- Check the places people publish addresses. Look at their personal website's contact page, their employer's staff or press page, conference speaker bios, university staff directories, the commit details on a public GitHub profile, podcast show notes, and the contact section of any academic paper they've written.
- Find the company's address format. Search
"@company.com"with quotes. Press releases, job ads and support pages often show real addresses. If you findjane.doe@company.comandsam.lee@company.com, the format isfirst.last. Note the variations: some companies usejdoeorjaned. - Search the name with contact words. Try
"Jane Doe" email,"Jane Doe" contactand"Jane Doe" "@company.com". A filetype search such as"Jane Doe" filetype:pdfcan turn up a CV or a paper with an address on it. - Use the platform's own messages. LinkedIn, X, Instagram and similar sites let you message someone without knowing their address. That's often the better first contact anyway.
- Ask for an introduction. A short forward from a mutual contact ("Jane, meet Sam, who asked about…") gets far better replies than a cold email.
Example walkthrough
Writing to a researcher about their paper
Illustrative example. The names, numbers and details are invented placeholders, not a real person or case.
You want to ask "Dr. Jordan Placeholder" a question about a paper. The PDF lists a corresponding author address at the university. The university staff directory shows the same address, so you write a short, specific, non-commercial note. If the paper had no address, the department's contact page and a LinkedIn message would be your next steps.
Rules for sending
Finding an address is one thing; what you send is regulated. In the US, CAN-SPAM covers all commercial email, including business-to-business, and requires honest headers, a postal address and a working opt-out. Canada's anti-spam law, CASL, generally needs consent before you send a commercial message, plus identification and an unsubscribe link. In the UK, PECR bars marketing email to individuals without specific consent, except to previous customers who were given an opt-out; companies can be emailed. Non-commercial personal notes fall outside these rules. A sales sequence to addresses you guessed is where people get into trouble.
Checking an address before you send
If you've guessed a pattern, send a short, clear first message rather than trusting a tool that "verifies" by probing the mail server. Many company servers accept every address, so those checks are often inconclusive. A bounce tells you the pattern is wrong.
Common dead ends, and why they fail
- "Email finder" and "verifier" tools. Many company mail servers accept every address, so a "valid" result often means nothing. Guessing and probing can also look like spam.
- Personal webmail. Gmail, Outlook and similar addresses aren't published in any directory. Unless the person posted it themselves, you won't find it, and you shouldn't buy it.
- Leaked or breached data. Addresses from breach dumps aren't a legitimate source, and using them to contact people is a fast way to be reported.
- Cold sales sequences to guessed addresses. This is where CAN-SPAM, CASL and PECR come in. See the rules below.
What if nothing works
- Message them on LinkedIn or another platform, or through a website's contact form.
- Phone the company's switchboard and ask the receptionist to pass on a message or give you the right address.
- Write a letter to their workplace. It's old-fashioned, and it gets read.
What people search for on this topic
The platform pattern from people search repeats: LinkedIn, Facebook, Instagram usernames, and in question form YouTube, Snapchat, Discord and Spotify. People want to get from a profile to an address.
Bing mixes in a separate intent: military records ("military service record", "military rank", "DoD ID from their email"). That's a misfire of "mail" and "military", but it's consistent enough to suggest a military-records guide is wanted.
"Work email" and "business email" are the B2B end of the topic, where email-pattern methods work.

FAQ
Can I find someone's personal Gmail address?
Only if they've published it. There's no public directory of Gmail or other webmail addresses.
Is it legal to guess someone's work email?
Guessing isn't illegal. Sending commercial email is regulated: CAN-SPAM in the US, CASL in Canada, and PECR and UK GDPR in the UK.
How do I find who owns an email address?
Search the address in quotes and look at the domain. For a company domain, the website tells you who it belongs to; for a webmail address there's no public lookup.
What if I can't find their email?
Use LinkedIn or another network's messages, or ask a mutual contact to introduce you.
Can I email someone whose address I found on their website?
Yes, for a personal or non-commercial message. Commercial messages are regulated: in Canada CASL generally needs consent, and in the UK PECR restricts marketing email to individuals.
Are email verification tools reliable?
Not very. Many company mail servers accept any address, so the tool can't tell whether a real person sits behind it. A bounce tells you more.
