To enable customers for Benchmark Email Authentication, a unique sub-domain is created under the main domain "bmsend.com." This sub-domain will be published in our DNS servers having unique authentication credentials for that customer. Please note that the domain "bmsend.com" should not be used in the "From" address field. Rather it is used in the "Sender" header field only.
Let us take an example of Benchmark Email itself for our monthly newsletters.
Example: Sender: "Benchmark Email" email@example.com
A unique sub-domain "benchmark" is created under the main domain "bmsend.com" for authentication on all the outgoing mails for the Benchmark Email account.
