DMARC, Domain Message Authentication Reporting and Conformance is an email authentication method that can be enacted on a domain and/or sub-domain level to inform mail receivers (Inbox providers like Google, Microsoft, etc.) how to treat email that fails authentication tests. One of the most noted benefits of enabling DMARC is that it allows senders to receive feedback on their email authentication performance and to identify email-based threats. In the case of the latter, DMARC allows a sender to publish Quarantine and Reject policies for email that fails DMARC compliance and have mail receivers block messages that aren't DMARC authenticated.
What does that all mean?
Essentially, through DMARC a sender informs a mail receiver about what to do to messages that don't pass email authentication tests. In doing so a sender builds a trusted email channel with Inbox providers, allowing mail receivers to block email-based threats such as phishing, spam, and malware and the sender to build a better email reputation to the inbox.
