  • Domain Overview
    dmarcian’s Domain Overview displays a summary of the status of all your domains and sources along with a geographical location of recent abuse. It is a great place to get started, as you can view the state of your domains at a glance so you can get to work locking down your email domains.
  • Detail Viewer
    The Detail Viewer is a comprehensive data discovery tool that allows you to explore your DMARC data in a variety of ways and to inform you on how to get your email sources compliant with DMARC.
  • Source Viewer
    The Source Viewer is where you get a quick, digestible view of where your mail is coming from and most importantly, what level of SPF, DKIM, and DMARC coverage each of your domains have. A Source is either a server under your control or a third-party platform that’s sending email on your behalf. dmarcian has a powerful classification engine that processes the underlying DMARC data and provides users with a human-readable tag on which third-party platform is sending the mail.
