Email is a vital tool marketers use to communicate with customers and prospects. Cyberattackers know this and will often impersonate trusted brands and domains in phishing campaigns. The Domain-based Message Authentication, Reporting, and Conformance (DMARC) protocol protects brands and domains from impersonation, boosting customer confidence in email communications and shielding the brand from those who would coopt it for nefarious purposes. This report helps security and marketing pros collaborate on DMARC to protect the brand, bolster customer trust, and defend against phishing.
