Case Study: Zillow achieves 161% email open-rate improvement with Bird (formerly MessageBird)

How Zillow Uses Email to Help Users Find Their Way Home

Zillow, the leading real-estate marketplace with more than 110 million U.S. homes in its database, needed a reliable way to nurture long-term relationships across the home-ownership lifecycle. Email is central to that strategy for time-sensitive alerts (new listings, open houses, mortgage info) and must be delivered at scale and on time, so Zillow partnered with Bird (formerly MessageBird) for email delivery and engagement infrastructure.

Bird provided a high-performance, API-driven email platform that ensured timely inbox delivery, handled surge volumes, and enabled measurement of opens, clicks, and unsubscribes as well as audience segmentation and trigger-based messaging. The solution helped Zillow achieve a 161% improvement in open rates and supported business activity tied to $965 million in revenue across its 110 million-home database, with Bird acting as an extension of Zillow’s team.
