Salesforce Marketing Cloud is an email marketing and customer engagement platform operated by Salesforce, Inc., serving as a comprehensive email service provider (ESP) for organisations managing customer communications at scale.
The presence of Salesforce Marketing Cloud's SPF includes on smaller and mid-market websites—particularly within the .com space and often alongside Microsoft 365—reflects its footprint among growing businesses that bundle marketing automation with Microsoft's productivity suite. For email professionals, this pattern matters: understanding SFMC's infrastructure helps explain SPF configuration choices on inbound mail and clarifies sender reputation dynamics when organisations use multiple platforms.

Organisations using Salesforce Marketing Cloud typically publish the platform's SPF includes in their domain's SPF record, delegating outbound mail authentication to Salesforce's sending infrastructure. This delegation is fundamental to SFMC's architecture—the platform operates shared sending pools and managed IP reputation on behalf of customers, meaning the platform's DNS configuration directly influences how receiving systems evaluate the sender's legitimacy. For deliverability engineers, auditing SPF records that contain SFMC includes reveals both the organisation's reliance on SFMC for message delivery and the interdependency between the customer domain's reputation and Salesforce's IP infrastructure.
