DMARC, or Domain Based Message Authentication, Reporting & Conformance, is a way to authenticate email messages originating from ones own domain. This improves deliverability, as well as increases domain reputation but the most important thing to note is that it protects emails from your domain against spoofing, phishing, and abuse.
DMARC is an open standard that everyone can implement
What is important to note that you do not only need to protect yourself from inbound threats, but protect your domain from outgoing email traffic.
Relying on spam filtering only, you give complete responsibility to a 3rd part to filter out the fake emails sent from your own domain. With this as well, legitimate emails might end up in the spam folder as well as emails with malicious attachments ending up in ones inbox.
Domain owners are responsible for who has the ability to send emails on behalf of your domains. In addition to implementing SPF and DKIM, DMARC makes the good messages visible and recognizable to the recipient. Adding DMARC to ones domain informs the receiver how to handle the email when a DMARC Check fails and who to provide feedback to.
