Email Waterfall Continues After Finding an Address

The email waterfall continues running because:

  • An email address was found, but the validation checker determined it is invalid
  • When validation fails, the waterfall automatically searches for additional valid email addresses

Solutions

  • Adjust validation settings to be less strict
  • Manually review and approve emails that may be incorrectly flagged as invalid
