Eloqua is Oracle's marketing automation and email service platform, acquired as part of Oracle's marketing cloud strategy. It handles campaign management, lead nurturing, and email delivery for marketing and customer-facing operations across a range of organisations.
Eloqua's footprint in the email infrastructure landscape is concentrated among smaller and mid-market organisations, predominantly in the .com space, and often appears alongside Microsoft 365. This distribution pattern means that mail teams receiving email from these organisations, or evaluating their domain's email authentication setup, are likely to encounter Eloqua's SPF, DKIM, and feedback loop mechanisms as part of the broader email ecosystem.

Eloqua operates as a multi-tenant platform where organisations delegate email sending to Oracle's shared infrastructure via SPF include mechanisms. This centralises authentication management but requires careful SPF, DKIM, and DMARC configuration to ensure Eloqua's servers are authorised to send mail on behalf of the domain. Because multiple Eloqua customers share the same sending infrastructure, organisations must monitor feedback loops and reputation signals to detect issues that might affect other tenants using the same pool.
