A DMARC policy protects and helps the email receiver systems to take proper actions when emails from unapproved sender domains are received. This helps to isolate potential threats.

A DMARC-policy is really important to have in place for your email deliverability. If you are not sure what a DMARC-policy is and how that is setup - please refer to this link:

In short

  • DMARC-policy is setup to procect you from Spoofing
  • If you have a DMARC-policy setup, the ISP recieving the email from a sender that impersonates your domain is able to send you a report back telling you this. Knowing that this has happened, you can then take actions to stop them from further attempts.
  • We recommend that you properly look through the parameters of the record and what they do. If you are still unsure, this is a good start for a DMARC-policy:

Note: If you are sending from a subdomain, please consult your domain admin if you should setup up a DMARC-policy specifically for the subdomain or if you should setup the policy for the root domain and allow the policy for the sub domains as well. For deliverability purpose, there is no preferred way.
Please remember to setup an email address for receiving your DMARC-reports. It can be as simple as dmarcreports@yourdomain.com. Let’s say that your company’s name is domain is acme.com, then the address can look something like this - dmarcreports@acme.com.
