After the static pre-check, we recommend that you upload your lists to our Email List Validation & Cleaning service for a full online validation (free for 1,000 email addresses):

• Syntax verification (IETF/RFC standard conformance)
• Automatic duplicate removal
• DNS validation including MX record lookup
• Disposable email address (DEA) detection
• SMTP connection and availability checking
• Temporary unavailability detection
• Mailbox existence checking
• Catch-All testing
