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.
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.
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.
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.
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.

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.

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.

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.

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.
Every address is verified live before it is returned, never guessed from a pattern.
No pattern guesses. The mailbox answered before we returned it.
Bulk CSV in, verified list out. Same speed on every plan.
The corpus behind every pattern the finder recognises.

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

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%.

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.

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.

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.

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.

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.

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.

Bulk upload, sorted CSV back in twenty minutes, plug into our growth stack. The half-day list-hygiene project per cohort turned into something the marketing intern runs on autopilot.

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
What teams ask before they switch: how the finder works, what the score means, and where the legal lines sit.
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.
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.
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.
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.
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.
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.
Finding a business contact for legitimate B2B outreach is permitted under GDPR's legitimate-interest basis, provided you honor opt-outs and follow CAN-SPAM. Verifox works only from the inputs you give it plus public sources; we never scrape platforms or resell contact databases. Submitted data is processed in memory, never stored, logged, or sold, and the service is SOC 2 Type II audited. The full stance is in the privacy policy.
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.
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.
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.
