A DMARC (Domain-based Message Authentication, Reporting, and Conformance) alignment solution offers robust email security for shipping companies by preventing email spoofing, enhancing deliverability, and protecting against phishing attacks. By specifying authorized email servers and authenticating sender domains, DMARC alignment ensures that incoming emails are checked against authorized sources, reducing the risk of unauthorized parties spoofing the company's domain. This measure not only improves email deliverability rates but also mitigates the threat of phishing attacks, where malicious actors impersonate the company to deceive recipients into divulging sensitive information.
