Automatic Subdomain Discovery
TDMARC offers the Automatic Subdomain Discovery feature that analyzes the entire outbound email channel of your domain and automatically lists down all of its subdomains. You can then apply filters on specific subdomains to see the data specifically related to them.
Take the domain name kratikal.com for an example.
If you click on ‘All Subdomains’, the TDMARC dashboard allows you to see the data combined for all the subdomains under this domain name.

You can also choose to see the data related to a particular subdomain, for instance, admin.kratikal.com.

Also, TDMARC doesn’t charge anything extra, no matter how many subdomains are associated with your domain.
