About Sender Score Accreditation

Sender Score accreditation is one program that comprises Sender Score Certified and Sender Score SafeList, the two largest third-party whitelists in the world. With Sender Score accreditation, you will find that as you improve the percentage of email that gets to the inbox, you will also see a correlated increase in your revenue and response.

A recent study by Return Path found that Sender Score Certified members experienced a 21% lift in overall delivery rates. Each percentage lift in delivery rates translates into increased program revenue and in many cases, significant savings. Along with the obvious financial advantages of improved inbox delivery, Microsoft recently announced that Sender Score Certified members will receive additional privileges when sending to Windows Live Mail users. The most significant is that images and links will be enabled by default for email sent from active, certified IP addresses. This means that Sender Score Certified senders can move past the challenges around rendering and image suppression that plague most email marketers.

To gain accreditation, email senders must adhere to a strict set of industry standards for email communication. Senders are not required to make any changes to their sending infrastructure or implement any proprietary technology to implement Sender Score Certified and Sender Score SafeList.
