We have opted for a sub-domain delegation configuration. After delegating the nameservers of the selected sub-domain to ET, Salesforce Marketing Cloud asked us to update MX records, create a mail box for the subdomain and initiate a whitelisting process. We were under the impression that once we delegated the sub-domain, we no longer had jurisdiction and SFMC would be able to complete all associated sub-domain configuration tasks. Does anyone have experience of delegating a sub-domain to SFMC and then being asked to configure the sub-domain mx records, create emails based on the sub-domain and whitelisting? Thanks


Depending on what info you have provided in the SAP order form. Usually, when you select the option of not hosting the DNS entries yourself, and delegate the subdomain to:


you will no longer have control of the domain, as everything is from then managed by Salesforce. Are you sure the subdomain CAN be delegated - or are there any existing entries for other purposes than Marketing Cloud sends/Cloud Pages?

  • Hi Lukas, The sub-domain was specifically generated for ET and we delegate them complete control. We were, thereforefore, confused by their subsequent request that we update MX records and create email inboxes based on the sub-domain. Also the white-listing request was a touch confusing.

  • You should push back, as you obviously can't manage DNS on a delegated subdomain. Have you checked the DNS records are set correctly, pointing at the NS servers above? Apr 9 '18 at 14:38

    Yes, all's validated. I think you're right, we need to make our point and ask for an accurate resolution.
