Email Discovery and Verification
Finding verified email addresses is critical for successful outreach. Here's how our system works.
How Email Discovery Works
When you click Find Email on a lead, LeadFinder Pro:
- Visits the company's website
- Scans for email patterns and contact pages
- Checks common email formats (first.last@, first@, info@)
- Cross-references with our data providers
- Returns the most likely email address
Email Verification
Our SMTP verification process:
- Checks if the email domain has valid MX records
- Connects to the mail server
- Verifies the specific mailbox exists
- Returns a verified/unverified status
Verification Statuses
- Verified ✅: Email confirmed deliverable
- Unverified ⚠️: Could not confirm — may still work
- Invalid ❌: Email does not exist
Best Practices
- Always verify before sending cold emails
- Verified emails have 95%+ deliverability
- Bulk verify to save time on large lists
- Re-verify emails older than 90 days
