DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol designed to mitigate the risks associated with email fraud and phishing attacks. DMARC enables domain owners to define which email servers are authorized to send messages on their behalf and provides feedback on email authentication results. For e-commerce businesses, adopting DMARC can help safeguard customer data and enhance email deliverability. By guaranteeing that marketing messages are authenticated and sent out effectively, businesses can elevate customer engagement, minimize the risks of fraud, and improve customer satisfaction.
