Customer service and support platform provider Zendesk has employed DMARC to monitor email activity using their domains for several years. In September, Zendesk switched over 80,000 sub-domains that they use to support their customers to a “p=reject” DMARC policy. This prevents fraudulent email using these sub-domains from reaching consumers, and protects their customers’ and Zendesk’s reputations as responsible email senders. DMARC.org hopes that other companies helping businesses support their customers through email will take similar steps to protect those customers from potential abuse.
