How to add DMARC?

63 1 20


I got an e-mail to add a DMARC to my account as Google and Yahoo making changes.




But the link to "learn how to create a DMARC" seems complicated with the google link:

Is there an actual tutorial for Shopify users to add DMARC with a easy tutorial?


Edit: It seems I need to connect to my domain host, which I don't know the domain host, I tried going to ICANN but it comes back as "No registry RDAP server was identified for this domain. Attempting lookup using WHOIS service." and "Failed to perform lookup using WHOIS service: TLD_NOT_SUPPORTED."

  • VALUE: Copy and paste this line: v=DMARC1; p=none;

 Is the same for everyone? ( I will use my store of course).


I add this record and it looks ok. But when i check there is a warning on:  



DMARC Policy Not EnabledDMARC Quarantine/Reject policy not enabled
13 0 2

We received the same errors, so I changed ours to this:

v=DMARC1; p=reject; pct=100;;; fo=1; ri=24; adkim=r; aspf=r

You can see what all of the options are for here:
