Mailbox Providers

We help some of the world’s most reputable mailbox providers create a safer, smarter inbox for email users. Fueled by the world’s most powerful email data platform, we work with mailbox providers to eliminate spam and keep consumers safe from email fraud.

Over the last 15 years Return Path has built a trusted data sharing network (RepNet) with some of the world’s largest mailbox providers. This network is a collaborative environment in which mailbox providers freely share data about senders of commercial email. Return Path acts as the clearing house for this data, combining it, analyzing it and scoring each sender. Return Path then shares back with all members of the network the aggregated scores that identifies good senders (a whitelist) and bad senders (a blacklist). Each mailbox provider can use these lists to constantly monitor and improve the user experience and protect them from SPAM.

To further enhance the partnership with mailbox providers, Return Path has also designed and built tools specifically for Post Masters to ease the burden of managing their environments. These tools range from quickly identifying bad senders within a mailbox providers own environment (Outbound Abuse Manager) to a collaborative exchange of SPAM trap hits (Global Threat Exchange), to outsourced sender complaint management (Feedback Loop Manager).

Return Path is also a champion and co-author of the Domain-based Message Authentication, Reporting & Conformance (DMARC) specification. Working in conjunction with mailbox providers Return Path’s Email Fraud Protection suite of products can also be leveraged to help with managing inbound fraud. As well as contributing DMARC authentication failures and forensic data back to Return Path to reduce the time of detection and close down phishing attacks.
