Three steps

From a name or a domain to a verified inbox

No scraping, no guesswork. Search by domain, name, or bulk CSV, let the engine generate and rank the candidates, then trust the one it confirms.

001INPUT

Enter a name or a domain

Search by company domain to map everyone we can identify there, by first name, last name, and domain for one person, or upload a CSV for the whole list. No scraping, no profile URL to hunt down.

002GENERATE

We rank every candidate

Verifox builds the address patterns the domain is likely to use, then cross-references them against public sources so the company's real format rises above the guesses.

003VERIFY

Verify before delivery

The best candidate is confirmed with a live SMTP handshake through the 9-point verification engine and returned with a 0 to 100 confidence score, not a guess.

The honest answer

What an email finder does

It turns the two things you usually have into the one thing you need: a work email that will actually be delivered.

An email finder service turns the two things you usually have, a person's name and the company they work at, into the one thing you need: a work email that will actually be delivered. Under the hood, Verifox does three jobs in sequence. It first studies how the target domain formats its addresses and generates the realistic candidates. It then cross-references those candidates against public sources, so the format the company really uses rises above the guesses. Finally it confirms the winner at the mail server itself, with a live SMTP handshake and mailbox ping, before the address ever reaches your screen.

The service, end to end

Four ways to find an address, one engine

Search by domain, by name, in bulk, or over the API. Every result comes back through the same 9-point verification engine before you see it.

Domain search

Map a whole account at once

Point the finder at a company domain and get back every address we can identify there, each with a job title, a confidence score, and the number of sources it was seen in. The fastest way to work out who is actually worth contacting.

Name lookup

One person, one address

Give it a name and a company and the engine models how that domain formats addresses, ranks the realistic candidates, and confirms the winner at the mail server before it reaches your screen. No permutation list for you to guess from.

Bulk

A CSV in, a clean list out

Upload names or domains in bulk and the same engine runs every row, deduplicates as it goes, and returns a file you can send from. Rows that fail verification are filtered out rather than padded back in to inflate the count.

API

Wired into your own stack

Every search available over REST, so the finder can run inside your CRM enrichment, your signup flow, or a nightly job. AI agents reach the same endpoints through the native MCP server, with identical verification on every result.

One search, every check

Everything the finder proves

Finding an address is half the job. Every address this finder returns has already been through the same nine-check engine the paid API runs.

What teams are saying

Built for the teams that ship outbound

Growth leads, marketers, and engineers running real campaigns on real lists, with a verified email on every byline.

Thomas George, GTM Lead at Stripe

90% lower bill, 0.4% bounces

We were paying ZeroBounce a four-figure monthly bill and still landing 3% bounces on cold campaigns. Switched the pipeline to Verifox, dropped to 0.4% bounces, and cut the bill by more than 90%.

Catch-all finally has a verdict

Other tools flag 30% of our B2B list as 'risky catch-all' and leave the call to us. Verifox returns a real verdict on those addresses, with a confidence score. We send more, we send safer.

Reputation rebuilt in 6 weeks

We had a Gmail spam-folder problem after a bad list import. Verifox cleaned the list and the warmup ran on the same engine. Back in primary inbox in six weeks. One vendor, half the cost.

0.7% bounce on 50k

Ran a 50,000-address outbound list through Verifox before our quarterly campaign. Bounces landed at 0.7%, sender reputation didn't move, replies were up 22% over last quarter.

MCP in 10 minutes

Their MCP server let me wire email verification directly into our internal Claude agent in about ten minutes. Zero glue code. No other vendor in this space has thought about that workflow.

10k/min held under 400ms

Tested Verifox at 10,000 verifications per minute on a Tuesday morning. Latency held under 400ms median, no soft failures, no rate-limit walls. The vendor we benched throttled at 2,000/min.

Hygiene that doesn't break pipeline

Our SDRs were enriching from three tools and 14% of the emails were invalid before they hit the sequencer. Verifox sits in the pipeline now and the team stopped seeing 'undeliverable' replies the next week.

Scores you can act on

Verifox returns a 0-100 confidence score per address, not just a label. We thresholded at 75 for the cold sequencer, 60 for nurture, and our deliverability team finally has a knob they can tune.

Common questions

The email finder service, answered

What teams ask before they switch: how the finder works, what the score means, and where the legal lines sit.

What is an email finder service?

An email finder service takes the details you already have, a name, a company, or just a domain, and returns the matching work email address. Verifox adds the step most finders skip: every address is verified at the mail server before you see it, so the output is a sendable contact, not a guess. You can try the self-serve email finder tool right now, no account needed to start.

How does Verifox find an email address?

In three stages. The finder first generates the address patterns the target domain is likely to use, the firstname.lastname and f.lastname variants you see in the wild. It then cross-references the candidates against public sources so the company's real format rises to the top. Finally, the best candidate is confirmed with a live SMTP handshake and mailbox ping through the email verification engine, and the result lands with a confidence score attached.

How accurate are the addresses the email finder returns?

Accurate enough to send to, because nothing unverified leaves the pipeline. The verification engine behind every result measured 99.99% accuracy on a 1,000-address benchmark list, and each found address carries a 0 to 100 confidence score so you can set your own bar. Addresses that fail verification are filtered out rather than padded into your export to inflate the count.

Should I search by domain or by name?

Search by domain when you know the company but not the people: a domain search maps every address we can identify there, the fastest way into a new account. Search by name when you know exactly who you want: a name-based email lookup tests the likely patterns for that one person and returns the strongest verified match with its confidence score.

What does the confidence score on a found email mean?

It is the engine's 0 to 100 estimate that the address will accept your mail. High scores are mailboxes confirmed at the SMTP level. Mid-range scores usually mean a catch-all domain, where the server claims to accept everything; that is where the AI-confidence layer earns its keep, since 20-40% of B2B addresses sit behind catch-alls. Low scores mean we could not confirm the mailbox, so you decide whether the send is worth the bounce risk.

Can I find email addresses in bulk?

Yes. Upload a CSV of names and companies, or a list of domains, and the bulk email finder returns the file with addresses, confidence scores, and verification verdicts filled in. The verification layer processes about 10,000 emails a minute on the standard tier, so even a large prospect list comes back the same morning, ready for your sequencer.

How is an email finder different from an email verifier?

A finder discovers an address you do not have; a verifier confirms an address you do. Verifox welds the two together: discovery runs first, then the 9-point email verification service inspects the result before delivery. If you already hold an address and just want a verdict, the free email checker gives you 4 verifications a day with no account at all.

Is there an email finder API or MCP server?

Both. The REST API exposes find-and-verify endpoints that return the address, the confidence score, and the verification verdict as JSON, so the finder slots into a CRM, a sequencer, or your own pipeline. For AI agents there is a native MCP server: point Claude, Cursor, or a custom agent at it and the find and verify tools are wired without glue code.

How much does the email finder service cost?

Starting costs nothing: sign up and you get 1,000 free credits, or 2,500 if you register with a work email, no card required. After that, credits are pay as you go and never expire, so an unused pack in March is still good in December. Volume rates are geo-localized, so the pricing page shows the numbers for your region.
