Zeta Global is a customer lifecycle management marketing company which was founded in 2007. Zeta has a self-service "Privacy Choices" page linked from its privacy policy, but there are two separate flows: one for identifiable data in the Zeta Data Cloud (requires verifying the email address tied to your data) and a separate real-time cookie/behavioral-advertising opt-out that only works in the browser you use, so you must repeat it per browser/device and after clearing cookies. California residents can also call 1.866.709.0840, and problems or appeals go to privacy@zetaglobal.com. Note Zeta's own published statistics show it fully or partly complied with only about 19,683 of 314,667 deletion requests in 2025, so expect a possible denial; stated response time is 30 days (Europe/Canada) or 45 days elsewhere, up to 90 in high-volume periods.
