Email Finder & Verifier API — Find Verified B2B Emails

Email Finder & Verifier API — Find Verified B2B Emails

You give: names + company domains directly, or a CSV/XLSX/Google Sheets file, or an Apify Dataset ID. You get: their verified, deliverable email address — one confirmed mailbox, with a confidence score, marked FOUND or NOT_FOUND. You pay: only per verified email found — $0.008. Not-found is free.

No LinkedIn, no scraping of protected sources. This is a deterministic pattern engine plus live deliverability verification — the two things that actually turn a name into an address you can send to.

Have LinkedIn profile URLs instead?

Use LinkedIn Email Finder — Verified Emails, No Cookies. Paste LinkedIn URLs/usernames and get profile + company context with a deliverability-checked email. $0.03 only when a verified email is found.

Need LinkedIn-based bulk prospecting?

Already have LinkedIn profile URLs? Use Bulk LinkedIn Email Finder — Verified Emails, No Cookies: https://apify.com/qualifyops/linkedin-email-finder-verified

Starting from target companies and need to discover employees or decision-makers first? Use LinkedIn Company Employees Scraper + Verified Email Finder: https://apify.com/qualifyops/linkedin-company-employees-email-finder

That gives you a simple QualifyOps ladder: name + domain → this Actor; profile URLs → Bulk LinkedIn Email Finder; companies → Company Employees + Email Finder.

Bulk input without JSON

You do not need to hand-format a JSON array. Paste a CSV or Excel file URL, a shareable Google Sheets link, or an Apify Dataset ID from another Actor. Common name and domain/website column names are detected automatically.

Lower-cost verification waterfall

Candidates are verified in rounds: the most-likely pattern for every unresolved person first, then the next pattern only for people still unresolved. That preserves the strict SMTP/catch-all gate while avoiding unnecessary paid verification calls.

Why "verified" is the whole point

Most email finders hand you first.last@company.com and call it a day. You send, it bounces, and your domain reputation takes the hit. Here, every FOUND address has been through:

pattern generation → syntax → MX record → live SMTP mailbox check → catch-all detection → confidence score

Only an address that a real mail server accepts, that is not catch-all, at confidence ≥ 0.80, is returned as FOUND. Everything else is NOT_FOUND with a reason and a clearly-labelled best_guess — never a silent, billed guess.

How it works

1. Normalize the name (lowercase, strip accents/punctuation) and the domain (strip https://, www., paths — full URLs are fine).
2. Generate candidates in priority order: first.last, first, flast, firstlast, first_last, f.last, last.first, lastf, first-last, last — each @domain.
3. Optional site scan (siteScan, on by default): fetch the company's homepage, /contact and /about and promote any published address that matches a candidate to the front — those are real, not guesses.
4. Local pre-filter (free): drop bad-syntax candidates and, if the domain has no MX record at all, return NOT_FOUND immediately — with no charge.
5. One batched deliverability check: survivors go to a proven Apify Store validator with real SMTP egress, in a single call per run.
6. Pick the winner: the first deliverable, non-catch-all, confident address becomes FOUND. You are charged only for FOUND.

What each row gives you

Column	Meaning
action	FOUND (verified deliverable) or NOT_FOUND (with reason)
firstName / lastName	The person you asked about
domain	The normalized company domain
verified_email	The deliverable address — only on FOUND
pattern	Which pattern won (first.last, flast, published, …)
confidence	0–1 deliverability confidence
source	pattern (generated) or published (found on the company site)
candidates_checked	How many addresses were tested
reason	On NOT_FOUND: catch_all_domain / all_rejected / no_mx / verifier_unavailable
best_guess / best_guess_confidence	On NOT_FOUND: the most-likely address, clearly not verified

Honest by design

• We never invent an address and label it verified. FOUND means a live mail server accepted that specific mailbox.
• Catch-all domains — which accept everything and confirm nothing — are returned as NOT_FOUND (catch_all_domain) and are not charged. We will not bill you for a domain that cannot actually confirm the person.
• If the verifier is unavailable, we degrade to NOT_FOUND (verifier_unavailable) — never a fabricated "deliverable" result, never a charge.
• A best_guess is always presented as a guess, never as a verified address.

For agents & automation

Call it via the Apify API or MCP. Pass an array of {firstName, lastName, domain} (or {fullName, domain}) and get back deduped, verified rows — ideal as a step in an enrichment pipeline. Schedule it for recurring enrichment of a lead list into your CRM or sequencer. You pay only for the addresses that are actually deliverable.
