To enable sending emails from a new domain (comms.nto.com.au) for Australian customers without impacting deliverability, Northern Trail Outfitters (NTO) must implement an additional Sender Authentication Package (SAP).
Sender Authentication Package (SAP): An SAP is a Marketing Cloud feature that authenticates a custom sending domain (e.g., comms.nto.com.au) to ensure emails are sent from a verified domain, improving deliverability and brand trust. It includes:
DomainKeys Identified Mail (DKIM): Signs emails to verify the sender’s identity.
Sender Policy Framework (SPF): Validates the sender’s IP address.
Domain-based Message Authentication, Reporting, and Conformance (DMARC): Enforces authentication policies to prevent spoofing.
Why it’s needed:
Using a new domain without proper authentication risks emails being marked as spam or rejected by email providers, impacting deliverability.
An SAP ensures that the new domain (comms.nto.com.au) is fully authenticated and aligned with email best practices, maintaining NTO’s sender reputation.
Implementation: NTO must purchase an additional SAP for the new domain, configure DNS records (DKIM, SPF, DMARC), and associate the domain with their Marketing Cloud account.
Why the other options are incorrect:
B. An additional IP address: A new IP address is not required for sending from a new domain. IPs are tied to the sending infrastructure, not the domain. Using a new domain with an existing IP is standard practice, provided the domain is authenticated via SAP.
C. An additional private domain: A private domain in Marketing Cloud is used for link wrapping and image hosting, not for sending emails. It does not address sender authentication or deliverability for the From address.
D. Register the new domain in Setup’s From Address Management: While registering the domain in From Address Management is a step in configuring the sending domain, it alone does not provide the full authentication (DKIM, SPF, DMARC) required to maintain deliverability. An SAP is needed to complete the setup.
