Case Study: Marks and Spencer achieves near-perfect email deliverability with Return Path Certification

Marks and Spencer optimises best-in-class email program with Return Path

Marks and Spencer, one of the UK’s best-known retailers, needed to protect the deliverability of its carefully curated email program as it expanded its list size and relied on subscriber data to send highly relevant messages to loyal customers. With email performance critical to driving traffic, revenue, and engagement, M&S turned to Return Path and its Certification program to ensure its campaigns continued reaching inboxes.

Return Path’s Certification program helped Marks and Spencer achieve near-perfect inbox placement by reducing filtering and throttling at major mailbox providers. As a result, M&S saw open rates increase by 20%, bounce rates fall by 86%, and click-throughs rise by 8%, while also improving delivery speed and giving the team confidence to scale broadcast volumes.
