Complaint Rate Calculator
Turn complaints and deliveries into a complaint rate. The check runs in your browser. MailShrine Email Sanitization flags invalid syntax, disposable and role-based addresses, and duplicates. It does not probe mailboxes, and it does not send the campaign.
Results appear here after you click Calculate.
