After you have added a DMARC record to your DNS, you’ll start receiving data pertaining to your email deliverability, domain usage, and domain security. Wondering what to do with it? Well, we’ll tell you just that! But first, you need to understand what a DMARC report is. What is a DMARC report? DMARC reports are authentication results from your domain. It acts as a feedback mechanism that helps the domain owner track email security and deliverability issues. The report also intimates the domain owner of malicious sources and protocol errors. DMARC reports are a goldmine of valuable information. This data can be used to strengthen a domain and take action against malicious sources while minimizing errors and deliverability issues. However, DMARC reports can be confusing to the average user due to their highly technical nature. The reports are of two types: DMARC Aggregate (RUA) Reports and DMARC Forensic (RUF) Reports. They are sent in XML format to the domain owner’s email address periodically. Let’s look at an example of a DMARC sample report and try to understand the different aspects it consists of.
