How to Add DMARC Record to AWS’s DNS-Route 53
This guide will show you how to add DMARC record to your domain. Experts at EasyDMARC strongly recommend to add DMARC (Domain-based Message Authentication Reporting and Conformance) record only for monitoring: with policy (p) = none. Here is the example

Remember, only DMARC record with “p=reject” policy is the most powerful and industry standard email authentication system. However achieving “p=reject” is hard, because putting it in DNS without proper monitoring, can get your perfectly valid emails to be rejected.
After a day or 2 email service providers will start to send DMARC XML reports to the email address that you have published in your record. You need to collect and analyze aggregated reports which can give you deep inside of you email flow.
Aggregated reports are in XML format and it is hard to analyze them. You can use free DMARC aggregated reports analyzer for visualization.
You can use the EasyDMARC to automate the process and receive notifications and suggestions to improve your email security.
