DMARC viewer

DMARC viewer is a Django-based web application that lets you visually analyze DMARC aggregate reports, providing unique insights into how your mailing domains are used and abused. Moreover, with DMARC viewer you can create and store custom analysis views that filter reports based on the criteria you are interested in.

Live Demo

A DMARC viewer demo is available at

Configure DNS

To receive DMARC aggregate reports for your domains all you need to do is to add a DMARC entry to your DNS records. Read "Anatomy of a DMARC resource record in the DNS" for initial guidance.

Start Analyzing!

To analyze your own DMARC aggregate reports you need to deploy an instance of DMARC viewer. Follow these steps to get you started:

  1. Deploy your own instance of DMARC viewer,
  2. import DMARC aggregate reports,
  3. and create analysis views.

Alternatively you can deploy DMARC viewer using docker.

You'll find further usage instructions on the DMARC viewer help page and plenty of contextual help throughout the website (look out for "?" symbols).
