Custom Domain or Subdomain Delegation

You can use domain or subdomain delegation, also called zone delegation, to configure your DNS. Subdomain configuration transfers only part of your existing custom domain to Marketing Cloud Engagement as part of your authenticated domain configuration. Engagement uses only the specified subdomain for appropriate activities.

Important Where possible, we changed noninclusive terms to align with our company value of Equality. We maintained certain terms to avoid any effect on customer implementations.

Note Subdomains are used for sending email messages with your company’s branding. For information regarding the subdomains used to construct your API endpoints, see Your Subdomain and Your Tenant's Endpoints.

As part of domain or subdomain delegation, you point a specific domain or subdomain, host, or zone name, to Marketing Cloud Engagement DNS servers. This sample shows the various configurations for a domain.

example.com - your domain name
www.example.com - your current website URL
server.example.com - the servers used by your custom domain
email.example.com - the custom subdomain to be used

In this example, you use only the custom domain or subdomain and nothing else. Other Engagement tasks don’t impact any other portion of your domain. This example uses the subdomain email.example.com, but you can specify a value other than “email” for the custom subdomain. Use a value that your subscribers recognize as part of your brand, because this value appears in the From Name of your email messages, as well as view-as-a-webpage, link wrapping, and image wrapping.

Configure Your DNS Settings

Enter these values for the subdomain to assign to Engagement.

ns1.exacttarget.com
ns2.exacttarget.com
ns3.exacttarget.com
ns4.exacttarget.com

Hyperforce DNS records:

ns01.ums-dns-salesforce.com
ns02.ums-dns-salesforce.com
ns03.ums-dns-salesforce.com
ns04.ums-dns-salesforce.com

Note Every DNS service appears differently. Be familiar with your service before attempting to make this change. Not all DNS servers or DNS service or domain registrar control panels support subdomain delegation. Contact your DNS provider to ensure you can use this service.

This example shows a typical DNS server configuration, including the applicable subdomain information shown in the last four lines:
