-
Company Domain Discovery: The tool attempts to determine the company's domain by first trying a direct approach (companyname.com) and then using Google search if needed.
-
Email Format Search: The tool searches Google for "email format for X company" to find the common email pattern used by the company (e.g., firstname.lastname@company.com).
-
Email Pattern Generation: Based on the discovered format or using common patterns, the tool generates potential email addresses.
-
Email Verification: The tool attempts to verify each potential email using multiple methods:
- Email format validation
- Domain MX record check
- Direct SMTP verification (checking if the mailbox exists without sending an email)
-
Results Presentation: Verified emails are presented with a confidence score.
- Email verification accuracy depends on the mail server's configuration. Some servers may not reject invalid recipients during the SMTP handshake.
- Google searches may be rate-limited if used extensively.
- The tool may not work if verification services change their page structure.
