The Domain Email Extractor That Verifies Every Address.

You give it a company domain, like acme.com, and it returns the work emails that belong to that domain. Verifox figures out how the domain formats its addresses, builds the realistic candidates for the people you want to reach, and cross-checks them against public sources so the right format rises to the top.

Every address is then run through our nine-check verification engine so you receive confirmed, deliverable emails, not raw patterns. We do not scrape web pages or harvest mailboxes, and you never need a login for the target company.

Verified. This is the difference between Verifox and a guess-only or scrape-only extractor. Every address goes through the same engine our paid verification API runs: MX record, SMTP mailbox check, catch-all detection, disposable and role-address filtering, and an AI-confidence pass.

You get a 0 to 100 confidence score on every result, so you can threshold what reaches your sequencer. If you only need to confirm a domain address you already have, the free email checker runs the same checks.

Free to start, with real numbers attached. Create a free account and you get 1,000 free credits on the spot, or 2,500 free credits if you sign up with a work email. No card required, and the sample extraction on this page costs nothing while you decide.

Ten credits cover one find-and-verify lookup, and credits are pay as you go and never expire, so an unused balance in June still works in December. Volume pricing is localized to your region on the pricing page.

Yes, and the workflow is built for exactly that shape of input. Upload a CSV with one domain per row (add name columns if you are targeting specific people) and Verifox returns the same file extended with the detected pattern, the found address, the verification verdict, the 0 to 100 confidence score, and a catch-all flag on every row. The verification leg runs at roughly 10,000 emails a minute on the standard tier, so a few thousand domains do not mean an overnight wait.

The bulk email finder covers the large-list workflow end to end, and lists that start from profiles rather than domains are better served by the LinkedIn email finder.

A typical web email extractor crawls a website and scrapes any mailto: strings it finds, which gives you stale shared inboxes like info@ and misses the actual decision-makers. Verifox works the other way: it generates the addresses real people at that domain use, then verifies each one.

The result is targeted, deliverable contacts rather than a pile of scraped role addresses. If you do want a single inbox confirmed, the email finder tool covers the full lookup workflow in both directions.

Yes. The extractor's AI layer ranks the candidate patterns by how that specific domain tends to format addresses, and an AI-confidence pass resolves catch-all domains that a rules-only extractor would leave as “unknown”.

The AI assists the ranking and the catch-all call. The final verdict still comes from a real SMTP-level verification check, so a confident-looking guess never ships unverified.

Yes, and this is where most extractors fall down. A catch-all domain accepts mail to any address, so a naive SMTP check reports every guess as “valid”. Verifox detects the catch-all, flags it, and leans on the AI-confidence pass and pattern evidence to score the most likely real address rather than rubber-stamping all of them.

You still get a clear confidence score and a catch-all flag on the result, so you decide whether to send now or route the address to a deeper verification step first.

The method matters more than the label. Regulators have penalized tools that bulk-scrape personal data off web pages and resell it, because the people in those databases never had a realistic path to object. Pattern generation sits on firmer ground: deriving a business contact's work address for legitimate B2B outreach is permitted under GDPR's legitimate-interest basis, provided you honour opt-outs and follow CAN-SPAM.

Verifox is built for the second model. We do not crawl or warehouse web pages; the domain you submit is processed in memory to generate and verify addresses, then discarded, never stored or sold. Verifox is GDPR and CCPA compliant and SOC 2 Type II audited, with the full breakdown in the privacy policy.

The verification engine behind every extracted address measured 99.99% accuracy on a 1,000-address benchmark list (self-measured), so a returned address carries real deliverability evidence, not a hopeful pattern. Each result also ships a 0 to 100 confidence score, letting you set your own threshold for cold sending versus nurture.

On speed: each verification pass runs at a median of about 380 milliseconds, so a full domain extraction (detect the pattern, build the candidates, verify each one) returns in a couple of seconds, and bulk jobs run the candidates in parallel. Uptime and incident history live at status.verifox.ai if you want the operational record before wiring it into a pipeline.

Yes, and the integration is one call deep. Send the finder endpoint a payload like {"domain": "acme.com"} and the response carries the detected pattern, the verified addresses, and a confidence score per result, ready to drop into a CRM record or a sequencer step. The REST API reference documents the request and response shapes, and HubSpot, Salesforce, Zapier, Clay, and Apollo all connect through it.

For agentic stacks, the native MCP serverexposes extraction and verification as tools Claude, Cursor, or a custom LLM app can call directly: paste the MCP URL into your agent config and a prompt like “extract verified emails for acme.com” just works, no glue code.
