How to Find Verified B2B Emails for Free (Without Paying $99/mo)

Most executives leave public digital footprints across company press releases, podcast interviews, and conference speaker lists. You can query these directly using advanced Google dorks:

Example query: site:company.com "email" OR "contact" "founder" OR "CEO"

By targeting exact corporate subdomains, you can extract exact email naming conventions (e.g., first.last@company.com or first@company.com) without purchasing credits.

Guessing an email format is only half the battle. Before sending an email, verify the destination server. Using an automated terminal or MX tester, verify that the domain has active MX records pointing to Google Workspace, Microsoft 365, or a dedicated private SMTP.

Never email unverified addresses from a new domain—a bounce rate above 2% will flag your sending IP in Spamhaus or Barracuda.

Instead of manually assembling spreadsheets, open Olonyn's Lead Finder. Input the target job title, industry, and location. In 30 seconds, the autonomous crawler identifies matching decision-makers, resolves corporate domains, verifies the email syntax, and outputs a clean CSV.
