Lookup an Email Address From Any Company Domain.

Yes. You start from the company's domain, not a name. Verifox surfaces the people who work there, so you pick the person you want and get their verified work email. Businesses assign addresses by formula, so once Verifox works out which formula that domain uses, it builds the candidates and confirms the one that actually exists.

The honest limit: personal inboxes have no formula to infer. This works for company domains, where addresses are standardized. Enter the domain and the lookup has everything it needs.

Enter the company's domain. Verifox surfaces the team behind it, infers the address convention that domain uses, assembles the plausible candidates for the person you want, orders them by that company's real formatting habits, then confirms the winner at the mail server with the same nine-check verification engine behind our paid API.

Nothing in that flow touches a private inbox or requires anyone's login. It is pattern inference plus a live deliverability check, not scraping.

That is the reverse direction: address in, owner out. This page goes domain-to-address; for the owner search, paste the address into the email lookup tooland it returns what the address itself reveals: the mailbox's existence, the domain behind it, its age, and whether it is disposable or a shared role inbox.

No tool can legitimately hand you a stranger's identity from a personal address alone. What you can verify is whether the address is real and what organization stands behind it.

Because there is no pattern to infer. Personal addresses on gmail.com or yahoo.com are whatever the owner picked at signup, so there is nothing to reconstruct. Work email lookup succeeds precisely because companies standardize their formats.

If you already have a personal address and just need to know it is real, the free email checker verifies any mailbox, consumer or corporate, in about 2 seconds.

You get a low confidence score or no result, never a dressed-up guess. The hard case is catch-all domains, where the server accepts mail for any address and a plain SMTP check cannot tell real from fake. 20 to 40% of B2B addresses sit behind catch-alls.

Verifox runs an AI-confidence pass on those domains and scores each candidate from 0 to 100. You decide where the cutoff sits, strict for cold sends, looser for nurture, instead of trusting a binary verdict.

Yes. Create a free account and you get 1,000 free credits immediately, or 2,500 if you sign up with a work address. No card required, and each credit covers a full lookup-and-verify.

Beyond the free credits, everything is pay as you go and never expires. Volume rates are shown for your region on the pricing page. No subscription, no monthly quota that lapses.

Yes. Hand a CSV of names and companies to the bulk email finder and every row comes back with three things: the address, the pattern that produced it, and its deliverability verdict. The list that comes out is sendable, not just enriched.

Bulk runs from a free account, and the same pipeline is scriptable through the REST API if your list lives in a CRM rather than a spreadsheet.

Both start from a company domain; they differ in what comes back. A lookup is precision: it surfaces the team, then returns the one verified address for the specific person you want. An extractor is breadth: the domain email extractor pulls every published address tied to the domain, useful when you want the whole company rather than one contact.

Both feed the same verification engine, so whichever direction you work from, the addresses that reach you are confirmed deliverable. The email finder hub covers the full toolkit.

For B2B outreach to a work address, yes. GDPR's legitimate-interest basis covers contacting people in their business role, as long as you honour opt-outs and meet CAN-SPAM's rules on your side. Verifox itself is GDPR-ready, CCPA-ready, and SOC 2 Type II audited.

On our side, the domain you submit is processed in memory, never stored, logged, or sold. The full data-handling breakdown is in the privacy policy.

Yes. Every lookup-and-verify endpoint is documented in the REST API reference, so the email address lookup drops into your CRM, sequencer, or enrichment pipeline. HubSpot, Salesforce, Zapier, and Clay all connect through it.

For AI agents, Verifox ships a native MCP server: point Claude, Cursor, or a custom LLM app at the MCP URL and the lookup and verify tools are available with zero glue code.
