We are going to use Marketing Cloud with Salesforce.
Per the instructions from Marketing Cloud, we will need to create a subdomain and then add four NS records for the subdomain to assign to Marketing Cloud
Subdomain has been created with our host WP Engine. (email.example.com)
CNAME record has been created and added to Cloudflare.
When visiting email.example.com, it redirects to the main URL…looks good.
I am having trouble with the NS part of the instructions from Marketing Cloud.
Each time I try to add a NS record, I get an error message that says “Non-NS records with that host already exist” error.
I was able to successfully create a sample NS record: sample.example.com.
So there is something with the subdomain name that was created “email”, that keeps giving me the error mentioned above when trying to create the needed four NS records.
When looking at the DNS records “Name” column, I don’t see anything named email, except for the new subdomain that was created, and then the CNAME record was created for this.
Any suggestions are greatly appreciated!
