Using your top-level domain (TLD) for the Sender Authentication Package (SAP) with Salesforce Marketing Cloud while simultaneously using it for corporate email is a common inquiry with a nuanced answer. While direct use of the TLD as the primary SAP domain is generally not recommended due to potential DNS conflicts, Salesforce Marketing Cloud offers a feature called Private Domain. This feature allows you to send emails with your TLD as the From address, even if your SAP is configured on a subdomain. This approach helps maintain strong email authentication and deliverability for both your marketing and corporate communications.
Key findings
Technical feasibility: It is technically possible to send from your TLD for marketing purposes, even when it is also used for corporate email, through Salesforce Marketing Cloud's Private Domain feature.
Subdomain for SAP: The recommended practice for SAP configuration is to use a subdomain (e.g., email.yourcompany.com) rather than the TLD itself.
Private domain functionality: After setting up SAP on a subdomain, you can add your TLD as a private domain, allowing you to send emails branded with your main domain.
DNS conflict avoidance: This setup bypasses conflicts with existing DNS records (like MX records) that are vital for your corporate email system.
Key considerations
DNS management: Managing DNS records for authentication is simpler with a subdomain. Salesforce typically provides the necessary DNS entries, but custom DNS hosting might be required for advanced setups.
DMARC alignment: The Private Domain strategy ensures DMARC (Domain-based Message Authentication, Reporting, and Conformance) passes through relaxed alignment, as the return-path domain will align with your SAP subdomain. Learn more about DMARC, SPF, and DKIM.
Reputation isolation: Using separate subdomains for marketing and corporate emails can help protect your primary domain's reputation. If your marketing emails encounter deliverability issues (e.g., getting blocklisted), it is less likely to affect your corporate communications. This is a best practice recommended by organizations like M3AAWG in their Sending Domains 101 document. Consider how subdomains affect your primary domain's reputation.
Cost implications: There may be an additional cost associated with purchasing a Private Domain SKU within Marketing Cloud.
What email marketers say
Email marketers often seek ways to align their marketing communications as closely as possible with their main brand identity, leading to a desire to use their top-level domain for email sending. While the technical complexities of integrating Salesforce Marketing Cloud's Sender Authentication Package (SAP) with an existing TLD can be daunting, the general consensus among marketers is that achieving this branding consistency is highly valuable. Many are willing to navigate the intricacies of DNS settings and additional features like Private Domains to ensure their emails are perceived as authentic and directly from their corporate brand.
Key opinions
Brand consistency: Marketers highly value the ability to send emails from their TLD to reinforce brand identity and trust with recipients.
SAP importance: They recognize SAP as a crucial tool for email authentication and overall deliverability, aiming to integrate it seamlessly with their existing domain strategy.
Subdomain is common: Many marketers are aware that subdomains are the more common and often recommended approach for SAP due to technical simplicity.
Interest in TLD solutions: Despite subdomain recommendations, there's a strong interest in understanding how to leverage the TLD for sending, indicating a priority for primary domain branding.
Key considerations
Balancing branding and deliverability: The challenge lies in achieving strong branding without compromising email deliverability, which heavily relies on proper authentication configurations.
Navigating technical requirements: Marketers need to understand the DNS entries and Salesforce-specific configurations required for both SAP and Private Domains. This can be complex, and resources like SFMC Stack's guide on SAP can be helpful.
Impact on corporate email: A primary concern is ensuring that marketing email configurations do not negatively affect the existing corporate email infrastructure or its deliverability. Refer to our guide on protecting your main domain reputation.
Cost vs. benefit analysis: The additional cost for a Private Domain SKU needs to be weighed against the perceived benefits of TLD branding for marketing emails.
Marketer view

What the experts say
Email deliverability experts consistently advise careful consideration when using a top-level domain for marketing emails, especially if it’s shared with corporate communications. Their insights highlight the technical challenges, particularly around DNS record management, and the best practices for maintaining domain reputation. They emphasize that while sending from a TLD is achievable in platforms like Salesforce Marketing Cloud, it typically involves specific configurations (like using private domains alongside a subdomain-based SAP) to avoid conflicts and ensure proper email authentication.
Key opinions
Subdomains are preferred: Experts generally recommend using a subdomain for SAP due to easier DNS record management and better isolation of sending reputation.
TLD sending is possible: It is not uncommon to configure Salesforce Marketing Cloud to send as the TLD, even if the primary SAP is on a subdomain.
Private domain functionality: The Private Domain feature in Marketing Cloud is key to allowing TLD sending while SAP remains on a subdomain.
DMARC compliance: This setup allows for DMARC to pass through relaxed alignment, ensuring authenticated sends. For more on DMARC, see our page on fixing common DMARC issues.
Key considerations
DNS record conflicts: The main reason against direct TLD use for SAP is potential conflict with existing DNS records, such as MX records, which are essential for corporate email traffic. This is a primary concern for email domain authentication best practices.
DNS hosting: Salesforce may not host customized DNS, implying that organizations might need to manage their own DNS for complex TLD configurations.
Deliverability impact: Using separate subdomains can help protect the overall domain reputation. If marketing emails cause issues (e.g., land on a blocklist or blacklist), corporate email deliverability is less likely to be impacted. Spamhaus provides marketing FAQs that touch upon domain separation.
Complexity: While feasible, the configuration for TLD sending can be more complex than a straightforward subdomain setup and requires a clear understanding of DNS interactions.
Expert view
Deliverability expert from Email Geeks states that while technically possible, they always recommend using a subdomain for SAP instead of a TLD, as it's easier to manage DNS records for authentication.

What the documentation says
Official documentation for Salesforce Marketing Cloud and general email industry best practices provide clear guidelines on domain usage for email sending. These sources primarily advocate for the use of subdomains for third-party email service providers (ESPs) like Marketing Cloud. However, they also detail how features such as the Sender Authentication Package (SAP) and Private Domains can be configured to achieve desired branding outcomes, even allowing the TLD to appear as the 'From' address. The documentation explicitly outlines the DNS records required and explains the underlying authentication mechanisms like SPF, DKIM, and DMARC that make these configurations work.
Key findings
SAP's dedicated domain: The Sender Authentication Package includes a dedicated domain feature designed for proper configuration and use by Marketing Cloud.
Private domain function: Private Domains enable sending mail from an authenticated domain, including comprehensive authentication like SPF, Sender ID, and DKIM.
DNS requirements: Specific DNS entries, including MX, A, and CNAME records, are needed for SAP setup, often pointing to Salesforce infrastructure.
Branding replacement: SAP aims to replace all references to Marketing Cloud with your authenticated domain for stronger branding.
Key considerations
Subdomain best practice: Industry bodies like M3AAWG recommend using a subdomain when sending through third-party platforms to protect the main corporate domain's reputation. This aligns with advice on using subdomains for marketing emails.
DNS maintenance: Salesforce provides specific guidance on DNS record maintenance for their ESP services. Conflicts with existing corporate DNS records must be avoided.
Reply mail management: SAP includes Reply Mail Management (RMM), allowing Marketing Cloud to handle replies to the 'reply to' email address, integrating with the chosen domain strategy.
Multiple SAPs vs. business units: While a Marketing Cloud account can have multiple SAPs, a single business unit only supports one SAP for branding, impacting how domains are structured across an organization.
