Company Finder: Find & Verify B2B Emails Without Leaving Your Browser (2026)

Company Finder: Find & Verify B2B Emails Without Leaving Your Browser (2026)

Most B2B prospecting workflows look like this: export a CSV from Apollo, paste into a spreadsheet, run a separate verification tool, copy results back, and hope nothing broke along the way.

Company Finder on Email Validator collapses that into one screen — search agencies by country and niche, scrape public contact emails from their websites, verify each address with the same SMTP pipeline as Single Check and the API, and save contacts to named lists you can reuse for outreach.

What Company Finder Does

Company Finder is built for teams who sell to other businesses — WordPress agencies, email marketing shops, SaaS vendors, and consultants who need real inboxes, not scraped platform addresses like sales@klaviyo.com.

Step What happens
Search Pick country, industry keywords, and optional filters
Scrape We fetch company sites and extract public emails + phones
Verify Each email runs through live SMTP/DNS validation
Save Add contacts to lists — segment by campaign, client, or vertical

Every verification uses verify_email_for_user() — the identical code path as your dashboard Single Check. No second-class results.


Verify Button = Single Check (Same Engine)

A common question: "Is Company Finder verification as accurate as your API?"

Yes. When you click Verify (same as Single Check) on a contact, we call the shared verification module — same MX lookup, same SMTP probe, same status taxonomy (valid, invalid, catch_all, risky, over_quota, etc.).

That matters because:

  • Status you see in Company Finder matches what bulk Excel and API return
  • Credits deduct under the same billing rules (valid, invalid, and over_quota consume credits; catch_all and risky do not)
  • List rows sync when you re-verify an address elsewhere on the account

Saved Lists: Copy, Move, Filter

Once you have contacts, Company Finder lists become your CRM-lite for outreach prep:

  • Copy selected → lists — duplicate contacts into another list (source unchanged)
  • Move selected → lists — relocate contacts when curating a campaign audience
  • Not on any list filter — find scraped contacts you haven't filed yet
  • Select all not saved — bulk-add stragglers in one click

Your last active list is remembered in the browser, so refreshing the page doesn't reset your workflow.


Practical Workflow for Agencies

Here is a workflow we use internally for agency outreach:

  1. Search email marketing + UK or HR
  2. Verify top contacts — keep only valid for cold email
  3. Save to a list named after the campaign (e.g. "Email marketing Agency")
  4. Export or connect to mass mail with valid-only preflight

Rule of thumb: treat catch_all as unconfirmed for cold outreach. The server accepts any address — SMTP cannot prove the inbox exists. Use them for research, not guaranteed delivery.


Company Finder vs Buying a Lead List

Purchased list Company Finder
Source Unknown, often aged Fresh from company websites
Verification Sometimes none Built-in SMTP verify
Segmentation Fixed Your lists, your rules
Compliance Variable You control who you add

Company Finder doesn't replace consent-based marketing laws (GDPR, CAN-SPAM). It gives you accurate contact data so you don't waste sends on dead addresses.


Getting Started

  1. Log in at email-validaton.com
  2. Open Company Finder from the dashboard
  3. Run a search, verify a handful of emails free-tier or with credits
