DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol that builds on SPF and DKIM. It lets domain owners publish a policy in DNS that tells receiving mail servers what to do when a message fails authentication -- deliver it, send it to spam, or reject it outright.
Beyond enforcement, DMARC also provides a reporting mechanism. When you add rua= and ruf= addresses to your record, you receive daily aggregate reports and (optionally) per-failure forensic reports. These reports give you visibility into who is sending email on behalf of your domain and whether it passes authentication.
A properly configured DMARC record with a policy of quarantine or reject is one of the most effective defenses against email spoofing and phishing attacks targeting your domain.
EmailQo helps you monitor deliverability, fix authentication issues, and make sure your messages actually reach your recipients.
