How to find business emails from a list of company domains

Method 1 — Website crawl (highest accuracy, slower)

Kavex's Website Scraper visits each company's domain, follows up to 4 contact-related pages, and extracts emails it finds in HTML (mailto: links + text patterns). Accuracy: about 65-75% of businesses have a discoverable email this way. Cost: 2 credits per page.

Method 2 — Pattern guessing + verification (faster, broader)

If you have first name + last name + domain, the Email Finder guesses the most likely pattern (firstname.lastname@, f.lastname@, firstinitial+lastname@) and runs each through SMTP verification. Returns the first one that passes with a confidence score. Cost: 5 credits per find.

Method 3 — LinkedIn + email pattern (highest signal, highest cost)

Use LinkedIn Company People to get the names of people in target roles at a company (e.g. "Head of Sales at Stripe"), then chain into Email Finder. This gives you both the right person AND the email — better than either alone.

• Step 1: /configure/linkedin-company-people, enter company URL + title filter
• Step 2: download the CSV of names
• Step 3: /configure/email-finder, upload the names + domain
• Step 4: optionally chain Email Verifier on the results

Quick verifier check — should you always verify?

Yes. Even a 90%-accurate email finder produces 10% bounces on a 1,000-email list, which damages your sender reputation. Email Verifier checks SMTP response per address (1 credit each) and flags catch-all domains.
