Return Path historically provided email deliverability and inbox placement measurement and diagnostic tools for high-volume senders. Functionality included seed-based inbox placement testing, reputation and blocklist monitoring, spam-trap detection, complaint tracking, and deliverability consulting to help senders identify and remediate issues affecting inbox placement.
Important market reality: Return Path as a standalone platform is no longer sold following its acquisition by Validity. Return Path capabilities have been consolidated into Everest, Validity’s current email success and deliverability platform. Return Path–branded assets remain (for example, Certification and Sender Score/RPBL tooling), but prospective buyers are generally directed to evaluate Everest as the current product offering.
