Product Notice: Sender "From" Address Validation Coming to Eloqua [Nov 2025]

With the arrival of Eloqua's 25D (Nov 2025), we're making configuration updates to enhance email deliverability in Eloqua.

Overview 

To better align with email deliverability best practices and enhance compliance, Eloqua is rolling out configuration changes to how sender “From” addresses are managed with the 25D release (Nov 2025). Please also note that domains configured and used for sending emails in Eloqua should be dedicated solely to Eloqua, and should not be shared with other marketing platforms or external systems. This approach supports deliverability best practices and ensures compliance with these new requirements. These updates will ensure all emails are sent exclusively from validated and approved sending domains—helping protect your sender reputation and future-proofing your email programs.
