Case Study: Cloudmark achieves safer, more accurate email filtering with Return Path

How Cloudmark Protects the Consumer Email Experience with Return Path Data

Cloudmark, a provider of carrier-grade messaging security and infrastructure for large mailbox networks, faced the challenge of filtering massive volumes of consumer email while blocking spam, phishing, and spoofing without sending wanted messages to spam folders. To improve accuracy and reduce false positives, Cloudmark partnered with Return Path and used Return Path Certification, whitelist, blacklist, and threat intelligence data.

With Return Path integrated into its filtering algorithms and security platform, Cloudmark could quickly identify trusted senders, focus computing power on suspicious traffic, and respond faster to email fraud. The result was stronger protection against abuse, detecting more than 99% of abusive email while reducing false positives to near zero, and Return Path helped Cloudmark make email safer and more reliable for end users.
