The Challenge

Find a customizable solution to connect, unify, and activate first-party data in a single platform to deliver personalized product recommendations to customers across all channels.

The Outcome

Tradera drove user engagement and increased sales, homepage click-through rates, and email open rates through personalized recommendations, advanced segmentation, and customer journeys.


Tradera is laser-focused on creating a more sustainable way of life as Sweden’s largest online marketplace for used goods. The company streamlines its auction process by having a fully-integrated system that handles the full gamut of transactional processes: item auctions, payment methods, shipping alternatives, reviews, etc. Tradera wanted a powerhouse of a system to similarly handle a variety of marketing processes, and ultimately chose Blueshift for the job.


Surface the Right Auctions, to the Right Users, at the Best Time

Tradera’s unique business model is driven by user listings. To deliver the right customer experience they need to understand varying data types across their buyers, sellers, and catalog. Tradera needed to find a solution that could collect, unify, and activate all their data from their website, mobile application, and email campaigns in a single location. They also needed something that was customizable and could connect with their existing systems.

In short, Tradera needed a customizable solution that would enable them to:

  • Become agile with self-serve capabilities that enable them to build precise audience segments and launch multi-channel campaigns
  • Deliver personalized recommendations to each user based on past purchases, website activities, popular items, lost auctions, and more at scale without IT or engineering resources
  • Manage their constantly-changing product catalog, often an inventory of 1, to surface relevant, live auctions across channels
  • Improve user experiences by delivering highly-engaging, consistent opportunities to connect across their website, mobile application, and email

“Blueshift has helped us optimize and keep track of how we spend our advertising money more precisely, instead of it just being a big blur.”

Pain Point

Legacy Solution Lacked Data Collection and Automation Capabilities

Prior to Blueshift, Tradera was using a legacy marketing solution that required substantial manual effort and limited the team to batch-and-blast email campaigns. They had no visibility into performance and couldn’t easily access their first-party data. Adding to the complexity, auctions vary in length, and they have a constantly changing catalog of millions of products. Tradera needed a solution that could handle their dynamic catalog and also surface the most relevant recommendations to each member.

“I would recommend Blueshift to companies that have a unique business model. Blueshift is completely customizable, and can adapt to business-specific needs in ways that show immediate and profound impact.”

Deliver Personalized User Experiences Across Channels

Tradera selected Blueshift because of its superior ability to adapt to their business-specific needs, in addition to the platform’s sophisticated architecture and AI capabilities. Blueshift allows them to deliver personalized auction recommendations across all of their marketing channels such as email, mobile, and web, helping their users to discover the most relevant listings to power growth.

Through the integration, Tradera was able to introduce an endless scroll of personalized product recommendations on their homepage that adapts to each user’s interests and latest behaviors. Their small team has also been able to drive user engagement through highly-targeted campaigns such as real-time auction updates, post-auction updates, new listings, and favorite sellers notifications.

The following capabilities were essential to Tradera’s success:

  • Single Customer View centralizes both buyer and seller data from their website and mobile app such as placing a bid, wishlist, losses, website visits, page loads, and app opens to build a holistic view of their users.
  • Personalized Recommendations leverages AI to personalize customer experiences across their website, email, and mobile app based on users’ previous purchases, viewed items, similar products, and other attributes.
  • Advanced Segmentation allows Tradera to create precise user segments such as active buyers, frequent sellers, best customers, and more to deliver highly relevant, engaging messages.
  • Cohesive Multi-Channel Customer Journeys ensures highly personalized, consistent user experiences across all channels and devices.
