Questions about the CNAME lookup
What is a CNAME record?
A record that makes one name an alias of another. Resolvers follow it and use the records of the target.
Can a root domain have a CNAME?
No. A root domain such as yourbrand.com holds SOA and NS records, and a CNAME cannot sit beside other records.
Why do tracking domains use CNAME records?
A custom tracking domain points to the sequencer's tracking server with a CNAME, so the links in your email use your own domain.
