How the email address lookup works
Three steps, no scraping, no guesswork. Give the lookup a name and a company, let it generate and rank the candidate addresses, then trust the one it confirms is deliverable.
002GENERATE
Generate the candidates
Verifox builds the likely address patterns and cross-checks them against public sources, so the right format for that domain rises to the top instead of a blind guess.
003VERIFY
Verify before you trust it
Every candidate runs through the same nine-check engine our verification API uses. You get back a confirmed, deliverable address with a confidence score, not a maybe.
Why this lookup
A lookup that verifies before it hands you the address
Most tools that lookup email addresses hand you a pattern and wish you luck. Verifox finds the address, then proves it is deliverable, so your bounce rate does not pay for the lookup.
Accuracy
9checks per address
Verified, never just guessed
Every address the finder returns is run through the same nine-check verification engine before you see it, so you forward a confirmed inbox, not a hopeful pattern.
Scale
10krows per upload
Bulk and CSV, built in
Find one contact here, or upload a list of names and companies and get a clean, verified CSV back. The same verification stack runs on every row.

The honest version
What it really means to lookup an email address
To lookup an email address is to start with a name and a company and end with the work email behind them. You know who you want to reach, you know where they work, and the one thing missing is the address itself. That is the gap this tool closes: hand Verifox the name and the company or domain, and it returns the email so you can actually start the conversation instead of staring at a dead end.
Here is the part most tools gloss over. There is no public directory you can read a private address straight out of, and Verifox does not pretend otherwise. What a good lookup does is smarter than that. It learns how a given domain formats its addresses, generates the realistic candidates, and ranks them by how that company actually builds emails. That is the email finder ai step, and it is why working from a domain is so much more reliable than typing a name into a generic search box. Need to go the other way, from a profile to an address? The LinkedIn email finder covers that same name-to-email path.
The candidate is only a lead until it is proven. So every address Verifox surfaces is run through the same find-and-verify pipeline that powers our paid product: an SMTP-level check, catch-all and disposable-domain filtering, and a confidence score from 0 to 100. The result is an address you can send to today, not a guess that bounces and dents your sender reputation. Wiring it into a sequencer, a CRM, or an AI agent? The same engine is available through the REST API, with pay-as-you-go pricing localized to your region on the pricing page.

What teams are saying
Built for the teams that ship outbound
Growth leads, marketers, and engineers running real campaigns on real lists. Specific numbers, specific tools they switched from, and a verified email address on every byline.
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%.
Thomas G.GTM Lead, Stripe
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.

Common questions
Email address lookup, answered
The questions we get from sales, recruiting, and growth teams that land here to look up a work email, with the real method, real limits, and the verification stance behind every result.
How do I lookup an email address for someone?
Give the lookup tool a person's name and their company or domain. Verifox builds the address patterns that domain is likely to use, then cross-checks the candidates against public sources so the right format rises to the top instead of a blind guess.
The address is then run through our nine-check verification engine so you receive a confirmed, deliverable email, not just a pattern. You never need anyone's login, and nothing about the lookup touches a private inbox.
Is the email address the lookup returns verified, or just a guess?
Verified. This is the difference between Verifox and a guess-only email address lookup. 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 with every result, so you can threshold what reaches your sequencer. If you only want to confirm an address you already have, the free email checker runs the same checks.
Is the email address lookup free?
You can run a few lookups from this page without an account, no card required. Create a free account and you get a batch of free credits on the spot to look up and verify more addresses.
After that, lookup credits are pay as you go and never expire, with volume pricing localized to your region on the pricing page. One credit covers a single lookup-and-verify.
Can I lookup email addresses in bulk from a list of names?
Yes. Upload a CSV of names and companies and Verifox returns a clean file with the found address, the matched pattern, and a verification verdict on every row, so the whole list is sendable, not just looked up.
Bulk lookups, CSV upload, and API access are available from a free account up. Most teams move to a pay-as-you-go credit pack once they are enriching lists regularly.
Can I look up an email by domain instead of a full company name?
Yes. The lookup accepts either a company name or a raw domain, so acme.comworks just as well as “Acme Inc”. Email finder by domain is the most reliable input because it removes any ambiguity about which company you mean.
Working from a website rather than one person? The domain email extractor pulls every address tied to a domain. And if you want an email owner search, the reverse question of who an address belongs to, the email finder tool covers the full lookup workflow in both directions.
Do you use AI to find the right email address?
Yes. The email finder AI 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 lookup 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.
How is this different from Hunter, Apollo, or RocketReach?
Those tools look up addresses and leave verification as a separate step or a separate product. Verifox verifies every address before it reaches you, so a found email is a sendable email. We also ship a native MCP server for AI agents that no other lookup tool offers.
On price, Verifox credits are pay as you go and never expire, rather than a monthly subscription where unused credits lapse. See the live, region-localized numbers on the pricing page.
Is it legal and GDPR compliant to lookup an email address?
Looking up a business contact's work email for legitimate B2B outreach is permitted under GDPR's legitimate-interest basis, provided you honour opt-outs and follow CAN-SPAM. Verifox is GDPR and CCPA compliant and SOC 2 Type II audited.
We process the name and domain you submit in memory to build and verify the address, and we do not sell your input or the result. The full breakdown is in the privacy policy.
How accurate is the lookup, and how fast?
Because the address is verified at SMTP level before you see it, the deliverable rate on returned addresses is high and the bounce risk is low. Each result carries a confidence score so you can set your own threshold for cold sending versus nurture.
A single lookup-and-verify returns in a couple of seconds, and bulk jobs process in parallel. Live uptime and incident history are at status.verifox.ai.
Can I add the email lookup to my own app or AI agent?
Yes. The REST API reference documents the lookup-and-verify endpoints, so you can wire the email address lookup into your CRM, your sequencer, or any tool that speaks REST. HubSpot, Salesforce, Zapier, Clay, and Apollo all connect through it.
Verifox also ships native MCP server support so AI agents (Claude, Cursor, custom LLM apps) can look up and verify addresses without glue code. Drop the MCP URL into your agent config and the tools are wired.
