Optimizing DMARC Authentication for Large Store Networks

Hi there,

We currently manage over 200 stores, and for DMARC authentication, we need to add 4 CNAME records per store. That means adding around 800 records—manually!

Is there a way to use generalized records that would cover all our stores? We’re constantly adding new ones, so this would be much more efficient. Additionally, I’m concerned that our DNS provider may have limits on the total number of records allowed.

Thanks in advance for any guidance!
