Bringing together over 70 major mailbox providers across the globe, the Return Path Provider Network is a trusted data-sharing ecosystem created to protect and enhance the email experience for consumers.
Return Path has built tools specifically designed for Postmasters to ease the burden of managing their email environments, where mailbox providers can quickly exchange spam trap data (Global Threat Exchange) or outsource sender complaint management (Feedback Loop Manager). Return Path also provides the Reputation Network Blacklist (RNBL), which identifies the worst senders so their mail can be blocked or filtered. Similarly, we provide the Certification whitelist to highlight the top tier of the sending community who adhere to strict sending standards to help mailbox providers ensure wanted mail reaches their customers. Finally, Return Path publishes Sender Score, a 0-100 reputation score to help evaluate sender behavior and incoming mail quality.
