The Challenge

Engage a growing user base at a hyper-personal level through AI-powered recommendations, tailored content, and dynamic customer experiences to scale campaigns and drive growth.

The Outcome

Zumper used personalized recommendations, advanced triggers, and testing and optimization to improve customer experiences for their existing renters and re-engage previous customers.


Zumper is an end-to-end rental platform that aims to make renting a place to live as easy as booking a hotel. Their dynamic business model makes it critical to stay on top of availability, pricing, user preferences, and levels of user intent. As Zumper’s user base grew, and the number of listings and customer requirements increased significantly, the need for a marketing solution to engage their audience at a hyper-personal level, at scale, became a necessity.

Pain Points

In-House Solution Functionality Could Not Keep Up with Evolving Business Needs

Finding a place to live can be an all-consuming and frustrating process, especially when time is of the essence. Zumper needed to keep users engaged throughout their apartment search, which can range anywhere between 1 week and 6 months, and adapt to evolving preferences accordingly. At the same time, they need to constantly provide multiple, relevant alternatives, as rentals can quickly disappear.

After building a solution in-house that was heavily reliant on engineering resources, Zumper realized their business needs were evolving too rapidly to match users to the right rentals. They needed a fast, flexible system that could keep up with millions of listings at any given time.

“If we had stuck with our old system, we’d need to add a number of people across the board, data scientists, data engineers, and marketers, to achieve the complexity of what Blueshift does for us today.”

Increase Renter Engagement and Listing Discovery Through Data-Driven, 1:1 Recommendations

Zumper needed a platform that would ultimately enable them to:

  • Increase Engagement Through Tailored Content
    Provide users with relevant listings and content personalized to their individual criteria, such as price, room size, term length or pet-friendly.
  • Re-engage Customers to Come Back In-market
    Remind customers who dropped off or who have a lease ending that Zumper is the go-to resource for the perfect rental.
  • Create Valuable, Dynamic Customer Experiences
    Craft dynamic, multi-stage lead flows that evolve with user preferences and behaviors, and keep users informed along the way.

“No customer journey is linear. Blueshift enables us to cater to the unique preferences of each renter. It’s a true extension of our product and helps our end users discover rentals that meet their search criteria.”

Hyper-Personalize and Scale Campaigns with Advanced Recommendations and Triggers

Zumper ultimately turned to Blueshift to improve its customer experience through an AI-powered, rather than rule-based, recommendation engine. Blueshift’s unmatched quality of AI-powered recommendations covered all of Zumper’s use cases.

The multifaceted messaging triggers and ability to bring in rental listings and catalog data enabled Zumper to tailor messaging in real-time based on catalog updates and user behaviors. Zumper benefited from Blueshift’s commitment to being a collaborative partner and as a result was able to scale with the evolving needs of the business.

Blueshift easily integrated with Zumper’s existing infrastructure. The platform quickly provided value and became an integral part of the multi-channel marketing approach within two months of launch.

The following capabilities were critical to Zumper’s success:

  • Personalized Recommendations to surface the right apartments for each user and help them discover new listings by matching user preferences (such as price, location, and amenities) and browsing behavior with Zumper’s constantly changing listing catalog. Blueshift’s solution automatically updates recommendations as user preferences evolve throughout the apartment search.
  • Advanced Triggers to create rich, real-time user experiences by triggering messages and actions based on user behaviors, apartment listing changes, segments, and more.
  • Testing & Optimization incorporated into every campaign and optimized for rental application submissions by continuously improving every element of its campaigns, such as subject lines, content, and templates.

“Blueshift’s AI-powered recommendation engine allowed us to better serve our customers with targeted marketing and personalized campaigns at scale. The platform enabled us to turn user behavior into experiences that capitalize on actionable insights that were critical to customer experience.”
