Just as PreferenceCentral was built in response to a growing demand for more user control over digital targeting and marketing, UnsubCentral was founded in 2004 to help marketers comply with the CAN-SPAM Act.

UnsubCentral was the first company to offer email suppression and campaign performance management solutions for advertisers, agencies, list managers, and affiliate networks. Since its inception, UnsubCentral has helped companies comply with the CAN-SPAM Act and data privacy requirements by allowing them to securely manage opt-out lists across the enterprise, affiliates and various third parties. Today, UnsubCentral is integrated with major affiliate networks and the leading email service providers. The mission is simple: to give advertisers, ad networks and affiliate networks the tools they need to conduct email marketing with confidence.
