Reach more subscribers and increase revenue.


Certified senders see inbox placement rates that are 32.5 percentage points higher

This happens at the top mailbox providers on average, compared to similar, non-Certified senders. How? Return Path Certification is the industry’s most powerful and unique whitelist, providing benefits at major mailbox providers and filtering companies to ensure your emails reach your subscribers.

More emails in the inbox means more opportunities for your customers to see your message, and ultimately drive increased ROI from the email channel. By not being Certified, marketers are leaving $135 billion on the table each year.


Certification is a powerful and unique program


Increase subscriber reach and ROI by receiving inbox placement benefits at major mailbox providers and filtering companies.


Understand email performance and impact through insightful, actionable data from mailbox providers.


Maximize email program performance with monitoring and support from Return Path.

Preferential inbox placement and decreased filtering aren’t the only benefits that Certification offers. Certification is much more than a whitelist; it’s a unique program that provides insightful, actionable data to help you send with confidence. Certified senders receive mailbox provider data from Return Path to help them understand the true impact of their emails.

The program also includes support and guidance along the way from Return Path. Our dedicated team provides 24/7 security monitoring, and you’ll receive alerts if issues are detected, along with specific recommendations on how to resolve them.
