Activate the Reply Mail Management feature in Marketing Cloud Growth

Only use these instructions for any subdomains that you created to use with Marketing Cloud Growth. If you authenticated your corporate root domain, consult with your DNS administrator to confirm that these instructions won’t cause a conflict with the inbound entries that are already in place. Reach out to Salesforce Global Support if you have questions.

Time Consideration

Please do not complete the delete domain steps below until your DNS administrator/IT team is ready to make DNS settings changes. Deleting the domain will prevent you from sending emails with Marketing Cloud, as email sending requires an active domain.

Known Issue Consideration

Currently there is a known issue that may affect your Salesforce DKIM Keys records when deleting domains from the Email Authenticated Domain page in Setup. Deleting domains as outlined by this knowledge article may inadvertently delete the Salesforce DKIM Keys records. Please work with your Salesforce admin during this deletion process to avoid any disruption to other outbound Salesforce email. For more information, please reference this known issue record.

Delete and Re-Add existing Domain

To show the new DNS entries in the Authenticated Domain setup, delete and re-add your existing Authentication Domain.

1. In the Quick Find box for Setup, enter Authenticated Domains, and select Email Authenticated Domains.
2. Select the domain that you want to enable for RMM, click the dropdown and select Delete.
3. Confirm Delete on the Confirmation Prompt.
4. Click Create New to recreate the domain.
5. Enter the domain name in the modal form and click Save.

Update Your DNS Records with new Inbound Records

1. In the Quick Find box for Setup, enter Authenticated Domains, then select Email Authenticated Domains. For each domain, click the dropdown and select Show Details.
2. When you access your DNS records (you may need to work with your IT team to review your current DNS records), make sure they include the below CNAME records. If any records are missing, work with your IT team to add them to your DNS settings. 
   
   

   Local Port (Host/Domain/Name/Alias)	Record Type
   bounce	CNAME
   leave	CNAME
   reply	CNAME
   anonymous	CNAME
   fbl	CNAME

3. For each CNAME record that you add, enter the Local Port, Record Type, Type, and Value. For additional help, review these DNS configuration tips.
4. In your DNS settings, update the DNS records to match the DNS records in your Salesforce org.

Activate your Authenticated Domain

1. After you create the new DNS entries, return to the Domain Details page by locating the domain that you want to activate.
2. Click the dropdown option for the Domain and select Details.
3. If the DNS records that you entered have propagated, you can use the enabled Activate button. If it is not yet enabled, allow some time for the DNS records to propagate. This process usually takes about an hour, but in some cases may take up to 48 hours.
4. Click Activate and wait for the domain activation process to compete.
5. When complete, the status of the domain should show as Active, both in the Authenticated Domain list and the Authenticated Domain Details page.
