How to Find Anyone's Business Email (2026): 7 Methods, Free Email Finders and What the Tests Show

The fastest way to find someone's business email is to enter their name and company domain into an email finder, then verify the result before you send. If you'd rather not use a tool, work out the company's email pattern from one known address and verify your guess. Never send to an unverified address, and never trust an email a chatbot gives you: in a September 2026 study, 76% of addresses produced by AI models were invalid.

We compared the free tools, the published accuracy tests and the official rules from Google, the FTC and the UK's data regulator, and flagged the widely repeated claims that are out of date.

The short answer

One address, right now: use a free email finder with the person's full name and company domain.
No tools: find one real address at the company, copy its pattern, then verify.
Hundreds of addresses: use a lead database or AI prospecting tool that verifies at the point you export.
Always: check every address with a verifier, and treat "accept-all" results as risky.

Find rate vs accuracy: why the tests disagree

Email finder tests produce wildly different numbers for the same tool because they measure different things. Saleshandy's September 2026 test of 14 tools gave Hunter 95% accuracy: of the addresses Hunter returned, 95% were valid. Emailchaser's 100-contact test found Hunter located only 67% of the people it searched for. Hunter's own study put its success rate at 64% of 305 lookups.

All three can be true at once. Accuracy measures how many found addresses are real. Find rate measures how many people you get an address for at all.

Hunter measured three ways: 95% accuracy of returned emails (Saleshandy), 67% find rate (Emailchaser), 64% valid-result rate (Hunter study) — Accuracy and find rate measure different things. Sources: Saleshandy, Emailchaser, Hunter, 2026

Two other caveats apply. Both Saleshandy and Emailchaser ranked their own tools first, and Saleshandy points out that most vendors publish accuracy figures without saying how they measured them. Mailmeteor, for example, advertises 97%+ accuracy on its finder page, but scored 70% in Saleshandy's test. The most rigorous public test Saleshandy found came from Anymail Finder, which checked 14 tools against 5,000 contacts using three independent verifiers and published its method, though it was also one of the tools tested. The safest approach is to run your own test on 20 people whose emails you already know.

Method 1: Use an email finder

Enter the person's first name, last name and company domain, and the tool tests common patterns, checks the mail server and cross-references its database. Mailmeteor describes exactly this three-step process.

A few habits improve results:

Use the full name. "Jonathan Smith" returns better matches than "J. Smith."
Confirm the domain first. Many failed lookups come from the right name on the wrong domain, such as a company's marketing site instead of its mail domain.
Check the result label. Most tools mark results as valid, risky or accept-all. Only "valid" is safe to send to without further checks.
Know the credit rules. Hunter, Saleshandy and several others don't charge when they find nothing. Saleshandy notes that Snov.io charges a credit even for results it couldn't verify.

Here's what a typical lookup looks like. Say you want to reach Maria Lopez, head of finance at a 300-person logistics company. You confirm on LinkedIn that she still works there and that the company emails from its main domain, not a regional one. You enter her full name and the domain into a finder, which returns maria.lopez@ marked "valid." Total time: under a minute. If it returns "accept-all" instead, move to the verification steps below before you send.

Method 2: Work out the company's email pattern

Companies use one format for everyone, so a single known address reveals the pattern for the whole organization. According to Sendburg data cited by MailTester.Ninja, based on 336,782 verified B2B addresses:

Format	Example	Share of addresses	When to guess it
first.last@	jane.smith@acme.com	47.7%	First guess, especially at large companies
flast@	jsmith@acme.com	26.8%	Second guess
first@	jane@acme.com	~9%	Startups and small teams
firstlast@	janesmith@acme.com	~6%	Some tech companies
f.last@	j.smith@acme.com	~5%	After the top four

Two formats, first.last and flast, cover about three-quarters of business addresses, and over 74% of companies with 10,000+ employees use first.last. Small startups lean toward first@.

To find a known address, check the company's contact, team and press pages, investor documents and author bios, or search the domain with an @ symbol on Google.

One warning: never send to every pattern to see which one bounces. Each wrong guess is a hard bounce against your domain, and the FTC treats generating addresses by "dictionary attack" as an aggravated CAN-SPAM violation. Generate the candidates, verify them, and only send to the one that confirms.

Method 3: Search the company's own pages

Companies publish more addresses than you'd expect: press contacts, partnership inquiries, conference speaker bios, PDF reports and job postings. This works best for founders, executives and anyone who deals with the public. It's slow but free, and even a generic address like press@ confirms the domain.

Useful Google searches include:

"@company.com" to surface any address published on the web at that domain.
site:company.com "email" OR "contact" to find contact pages and staff listings.
"Jane Smith" "@company.com" to look for the person's exact address in documents and directories.
site:company.com filetype:pdf to find reports, brochures and investor documents that often list contacts.

Method 4: LinkedIn and browser extensions

LinkedIn rarely shows email addresses, but it confirms the three inputs every other method needs: the exact name spelling, current employer and role. Browser extensions that display emails on LinkedIn profiles are only as good as the database behind them. Some pull verified records, while others guess from patterns.

The UK's data regulator adds a nuance. Its B2B marketing guidance says people often use professional networking sites in a personal, if professional, capacity, so messaging them there isn't automatically treated as B2B marketing. Use profiles to research people, and email their work address.

Method 5: Just ask

For a handful of high-value contacts, a short message asking for the best email to reach them often works and warms up the conversation. It doesn't scale, but for a key account it's frequently the fastest route.

Method 6: Use a verified lead database

When you need hundreds of contacts, one-by-one lookups stop making sense. A B2B lead database or AI prospecting tool searches by role, industry and company size and returns verified emails in bulk. The quality question is when the data was last verified: B2B email data decays at roughly 22.5% a year, as covered in our B2B email list guide. Prefer tools that verify at the moment you export, such as Spona, which builds verified lists from 40+ sources, and use waterfall enrichment to fill gaps from multiple sources.

Method 7: Don't ask a chatbot

It's tempting to ask ChatGPT or another AI model for someone's email. Hunter tested exactly that in September 2026, sending 915 prompts to each of several models and verifying every address they returned:

76% of AI-generated addresses were invalid, 10% were accept-all, and only 14% were valid.
The strongest model returned a valid contact only 19.5% of the time.
Pushing harder made it worse. Telling a model "don't leave the email blank" cut refusals to 1%, and the gaps were filled with made-up addresses.
Connected to a real data source, the same model's success rate rose to 78%.

AI is useful for deciding who to contact. The email itself has to come from a verified source.

A bulk workflow for lists

Once you need more than a handful of addresses, the one-by-one methods above turn into a process:

Build the account list first. Define the companies that fit your ideal customer before you look for people. Our guide to building a lead list covers this step.
Pick roles, not names. Decide which job titles you need at each account, then let a database or finder return the people.
Find in bulk. Upload names and domains to a bulk finder, or export directly from a database.
Verify everything. Run the full list through a verifier, even if the tool says it's verified, and separate valid, accept-all and invalid results.
Cap the risky segment. Send to accept-all addresses only as a small slice of each campaign, following Hunter's 2–5% guidance.
Re-verify before each new campaign. A list that was clean three months ago won't be clean today.

How to verify an address before you send

Verification tools check that the syntax is valid, that the domain can receive mail and, through a server handshake, that the specific mailbox exists, all without sending an email.

The hard case is accept-all domains, also called catch-all. These servers accept mail for any address, so a verifier can't confirm whether a specific mailbox is real. They're common: Hunter found 38% of domains in a 2,572-address sample were accept-all, and MailTester puts the share of addresses at about 25%.

Bounce rates in Hunter tests: 1% for valid addresses, 27% for accept-all addresses, 0% for Google addresses converted to people chips, 56% for unconverted ones — Bounce rates by verification result. Source: Hunter accept-all experiments

In Hunter's test, emails to accept-all addresses bounced 27% of the time, against 1% for verified addresses. Hunter recommends keeping accept-all contacts to 2–5% of any campaign, or reaching them through another channel. For Google-hosted addresses, Hunter also found that addresses Google Sheets could convert into a "people chip" bounced 0% of the time, while unconverted ones bounced 56%.

A "risky" result isn't always a catch-all. Mailmeteor notes it can also mean the receiving server was rate-limiting verification checks, so it's worth re-checking those addresses later before you discard them.

Re-verify any list older than about 90 days, because people change jobs and addresses stop working.

Finding emails for specific roles

Senior roles follow the same company pattern as everyone else, so the methods above still apply. The difference is where to look first:

CEOs and founders appear in press releases, funding announcements and investor materials, which often include a direct address.
CFOs and finance leaders are named in annual reports and investor relations pages at larger companies.
HR and recruiting leaders often post from their work address on job listings and careers pages.
IT and security leaders speak at conferences, and speaker bios regularly include contact details.

If you need many people in the same role across an industry, such as every CFO at mid-sized logistics companies, a role-filtered search in a tool like Spona is far faster than finding each name first.

Finding emails at small and local businesses

Small companies break most of the rules above. They often have no consistent pattern, use the owner's first name only, or run email on a personal Gmail address. Pattern data reflects this: bare first@ formats are far more common at startups and small teams than at enterprises.

For local businesses, start with the company's website, Google Business Profile and any industry directories, which often list the owner's name and a contact address. Remember the UK rule above: sole traders are treated like individuals, so business-to-business exemptions don't apply to them. If you need owner names before you can look for emails, our guide to finding a business owner walks through public records and other sources.

Email finder vs verifier vs reverse lookup

These three tools are often confused:

Email finder: starts from a name and company, returns an address you didn't have.
Email verifier: starts from an address, tells you whether the mailbox exists.
Reverse email lookup: starts from an address, tells you who owns it and where they work.

Most finders include basic verification, and Saleshandy notes several tools bill finding and verifying separately. Hunter, for example, charges 1 credit to find an address and half a credit to verify one.

When nothing works

Sometimes every method fails. That usually means one of four things: the person has left the company, they use a non-standard alias, the company runs an unusual format, or the domain is accept-all and won't confirm anything.

Check LinkedIn to confirm they're still in the role, then try the top two patterns through a verifier. If nothing confirms, reach the person through a different channel, such as a phone call or LinkedIn message, rather than sending to an unverified guess. One missing contact costs you nothing. A bounce costs you deliverability across every email your domain sends.

Claims that don't hold up

Claim	Where it appears	What primary sources show
Hunter's free plan gives 25 searches (or ~150 credits)	no2bounce; an old Hunter blog post; Surfe	50 credits a month (Hunter help center, Aug 2026)
Use Clearbit to look up or verify emails	IT Now Technologies (Mar 2026)	Clearbit's free tools were retired April 30, 2025 (Clearbit)
Mailmeteor finds emails with 97%+ accuracy	Mailmeteor	70% in Saleshandy's 14-tool test
Google requires bounces under 2%; 5% triggers filtering	MailTester.Ninja; SalesTarget	Google sets spam-rate limits (below 0.10%, never 0.30%), not a bounce % (Google)
GDPR usually requires consent for B2B email	no2bounce	ICO: legitimate interests is the likely basis for emailing corporate subscribers

The Hunter free-plan confusion is the clearest example of stale content. no2bounce says Hunter's free plan offers 25 searches, matching a Hunter blog post last edited in August 2026 that still lists old plans. Surfe says about 150 credits. Hunter's help center, updated August 20, 2026, says 50 credits a month, where finding an email costs 1 credit and verifying one costs half a credit. Similarly, IT Now Technologies still recommends Clearbit for email lookups, although Clearbit retired its free tools on April 30, 2025.

Bounce-rate rules are similarly muddled. MailTester says Google's guidelines direct senders to keep bounces under 2%, and SalesTarget says bounces above 5% trigger active filtering. Google's sender guidelines set no bounce percentage. They require spam rates below 0.30% and recommend staying below 0.10%. Low bounce rates still matter, but the 2% and 5% figures are industry rules of thumb, not Google requirements.

Is it legal to find and email someone?

Finding a public business email is generally legal. Emailing it is governed by the recipient's country:

United States: CAN-SPAM covers B2B email with no exception. Each violating email can cost up to $53,088, and you must include a physical address, a clear opt-out, and honor opt-outs within 10 business days.
United Kingdom: the ICO says the PECR email consent rule doesn't apply to corporate subscribers such as limited companies, but UK GDPR still applies to named contacts. Sole traders and some partnerships are treated as individuals and need consent. If you get data from a third party, you must give people privacy information within one month.
European Union: GDPR allows B2B prospecting under legitimate interests in many cases, but national email rules vary, so check the country before you send.

Contrary to no2bounce's claim that GDPR "usually" requires consent for marketing emails, the ICO lists legitimate interests as the likely basis for emailing corporate subscribers. This is general information, not legal advice.

FAQ

How do I find someone's business email for free?

Enter their name and company domain into a free email finder such as Hunter (50 credits a month) or Mailmeteor (free single lookups). Without a tool, find one known address at the company, copy its pattern and verify the result with a free checker.

What is the most common business email format?

firstname.lastname@company.com, used by 47.7% of 336,782 verified B2B addresses in Sendburg's data. First initial plus last name (jsmith@) comes second at 26.8%.

How accurate are email finders?

It depends on the metric. Saleshandy's test found 70% to 98% of returned addresses were valid across 14 tools, while find rates in other tests were lower: Hunter found 67% of people in Emailchaser's test. Run your own test on 20 known contacts.

Can ChatGPT find someone's email address?

Not reliably. In Hunter's September 2026 study, 76% of addresses produced by AI models were invalid. Models only became reliable when connected to a verified email database.

What does accept-all mean in email verification?

The domain accepts mail for any address, so the verifier can't confirm the mailbox exists. In Hunter's test, accept-all addresses bounced 27% of the time, compared with 1% for verified ones.

Is it legal to email someone whose address I found online?

Usually, for relevant B2B outreach, if you follow local rules. In the US, CAN-SPAM requires a physical address and a working opt-out. In the UK, emails to limited companies don't need prior consent under PECR, but UK GDPR still applies.

How many emails can I find for free?

Most free plans cover 25 to 50 lookups a month. Hunter gives 50 credits, GetProspect 50 valid emails, Lusha 40 credits and Apollo 900 credits a year, according to Hunter's help center and Saleshandy's 2026 comparison. Mailmeteor allows unlimited single lookups but no bulk searches.

How do I find the email of a CEO?

Use the same methods: an email finder with the CEO's name and company domain, or the company pattern. Founders and executives often publish addresses in press releases and investor materials, so check those first.
