Can we use sender authentication private domain?
I need to verify a domain to use different senders in Marketing Cloud (companydomain.com). We already have a Sender Authentication Package that is a subdomain of our domain (sap.company domain.com), but we need to use some emails as sender which they are from our domain (user1@companydomain.com, user2@companydomain.com …). These senders change a lot and sometimes we need to use Dynamic Senders, so I saw two options: use either a Private Domain or a Domain Registration. Can anybody help me with two doubts about it:
Private Domains allows you to send mail from an authenticated domain (https://help.salesforce.com/articleView?id=000318538&language=en_US&type=1&mode=1) This means that the send with a sender from a registered a Domain will not be authenticated or it depends on the configuration in our domain?
Can We use our domain as a private domain? Or it needs to be a subdomain (a non-existing domain)?
You will be able to send from the top level domain of your company (e.g. as john@company.com) by purchasing and configuring a sender authentication Private Domain on your company.com domain. Assuming you already have your SAP in place on e.g. marketing.company.com. Those that need to be within the same top domain as DMARC will otherwise fail. As in most cases for SAP, the subdomain is delegated to Salesforce name servers, and all DNS configuration is managed by their team. This is obviously not possible with regards to you top domain, so you will be provided with a set of DNS records to be updated in your existing zone of company.com Also managing RMM in SFMC will not be possible, as MX records for company.com already point to your existing mail servers
