DMARC (Domain-based Message Authentication, Reporting &Conformance) is an email validation system that allows you to set policies on who can send an email using your domain based on DKIM and SPF. This email validation system is set up in such a way that if the DKIM and SPF fail, DMARC would initiate action.

If the record detects a misalignment between email sender and the address, DMARC activities a protocol which tells the receiving server to accept, quarantine, or reject the message based on the policy defined by the sender.

What is a Feedback Loop?

Feedback loop allows senders to receive alerts from users who complained or reported this particular sender as a spammer. The mailbox provider forwards this message to the sender's specified email address that has been set up, so the sender can suppress or permanently remove this user from their active list.

What is Email Authentication?

Email authentication a process that verifies that an email comes from who it claims to be from. It allows the mailbox provider to approve that the sender is the one who he assumes to be. Most common email authentication standards are DMARC, DKIM, and SPF.
