Cloudmark provides carrier-grade messaging security and infrastructure solutions for the world’s most demanding fixed, mobile and social networks. In just 60 seconds a single spam run can drop more than one million messages into a mailbox provider’s network. To protect their account holders from email abuse like this, more than 120 of the world’s largest mailbox providers including AT&T, Comcast, Cox Communications, and Verizon turn to intelligent network security solutions from Cloudmark. Return Path is proud to play a critical role in this mission as a partner with Cloudmark, providing whitelisting and blacklisting solutions and critical threat intelligence data. Our collaboration helps to protect consumers around the world from spam and phishing attacks while ensuring that the messages they want reach the inbox.

Challenge

Commercial email represents a unique filtering challenge for mailbox providers. While marketing messages are typically not a priority for enterprise and business network users, they are clearly important to consumers. So consumer mailbox providers face increased pressure to ensure that the marketing messages their users want aren’t diverted to spam folders or blocked.

Solution

In response, Cloudmark developed spam filtering technology and logic that addresses both challenges faced by large consumer networks: the need to keep abuse out of the inbox, and the need to deliver the email that people want and expect. Return Path Certification plays a critical part in Cloudmark’s exceptional filtering accuracy, which detects more than 99 percent of abusive email while reducing false positives to near zero.

Marketers that qualify for Return Path Certification and inclusion in its industry-leading whitelist comply with stringent requirements, following consumer-friendly best practices to empower subscribers and reduce complaints. By incorporating the Return Path whitelist into its filtering algorithms, Cloudmark instantly identifies messages from these legitimate, trusted senders, which means that it can focus its computing power on assessing suspicious messages. Angela Knox, VP Engineering at Cloudmark, says her company has complete confidence in Return Path Certification and the role it plays in Cloudmark’s filtering.

“Return Path provides data we can trust. That’s why content that comes from senders on Return Path’s whitelist is given preferential treatment,” Knox said. “It helps us make faster, more accurate decisions that keep our clients’ networks safer while delivering a better, more secure experience for their end users.”

Cloudmark’s mission extends beyond reducing spam to combating cyberthreats such as phishing and spoofing. Return Path directly contributes to these efforts, too. Cloudmark’s Security Platform for Email runs on an adaptable workflow engine that uses current threat data to adapt and protect users against future threats from email fraud. By incorporating Return Path’s proprietary email threat data and its blacklist of known malicious senders, Cloudmark significantly increases the number of email-borne threats it detects while decreasing the time it takes to find and respond to email fraud.

Results

“Return Path has been integral in helping us identify and eliminate abuse, making email safer for everyone,” said Knox. “Together we’ve worked on major anti-spam and anti-fraud initiatives like DMARC, with the common goal of safeguarding trust and security in the email channel. We’ve made great strides, largely because of the support we get from technology partners like Return Path.”
