Here is how you can verify if the DNS values are set up properly or not on your DNS hosting server.
Once you are on-boarded to MassMailer, you will receive a google sheet that provides the DNS values that you need to set up such as CNAME, A, SPF, DMARC, BIMI records.
Once the DNS values have been set up on your DNS hosting provider you can check them by going to:
and enter the respective HOSTNAME into the corresponding DNS RECORD Type.
You can verify all other DNS records if they have been propagated or not. If you see any problem you can work with your DNS hosting provider support team to resolve it.
