Understanding Confidence Scores

Every email address returned by our domain email finder includes a confidence score that helps you prioritize your outreach and minimize bounce rates.

High Confidence

90-100% confidence score indicates the email format is very likely in use based on verification results.

Medium Confidence

70-89% confidence means the format is likely in use, though other formats may also be active at this domain.

Low Confidence

Below 70% suggests the email may be inactive and poses a higher bounce risk. Verify before using.

Confidence scores are calculated based on SMTP checks, source reliability, email pattern matching, and verification against public databases.

Email Pattern Detection

Our domain email finder automatically detects the most common email patterns used by each company, helping you construct additional email addresses when needed.

Pattern FormatExampleCommon Usage
[email protected][email protected]Most common format
[email protected][email protected]Small companies, startups
[email protected][email protected]Tech companies
[email protected][email protected]Less common, some SMBs

Companies often use multiple email formats. Our tool identifies all patterns in use and provides confidence scores for each.

Why Email Verification Matters

Finding email addresses is just the first step. Without verification, you risk high bounce rates that damage your sender reputation and reduce email deliverability for all future campaigns.

Our Verification Process Checks:

  • Syntax validation: Proper email format
  • Domain validation: Domain exists and accepts mail
  • SMTP verification: Mailbox exists and can receive email
  • Catch-all detection: Identifies accept-all domains
  • Disposable email check: Filters temporary addresses
  • Pattern matching: Confirms against known formats
