Zwarte Roes is a Dutch specialty coffee roastery dedicated to offering high-quality alternatives to mass-produced supermarket coffee. Their approach focuses on small-batch roasting techniques that bring out the unique flavor profiles of carefully selected coffee beans.
While they began as a local business, they've been actively building their online presence for the past four years, implementing various marketing tools and advertising platforms to reach coffee enthusiasts throughout the Netherlands.
Marvin, one of the owners of Zwarte Roes, had been using TrackBee since June 2024 to enhance their Meta and Google Ads campaigns with great success. TrackBee had initially approached Zwarte Roes about improving their advertising tracking, and it had quickly proven its value for their advertising platforms. "We weren't really searching for a solution. We were approached by TrackBee," Marvin shares. "I found it interesting because we're always trying to improve our performance on Meta and Google."
While their paid advertising was performing well with the help of TrackBee, Marvin recognized they weren't maximizing their email marketing potential. In early 2025, Zwarte Roes set a goal to significantly improve their email marketing performance as part of their overall strategy.
At this point, their email marketing strategy with Klaviyo was limited to only running checkout abandonment flows. They weren't yet using abandoned cart flows and were missing a major opportunity to re-engage with potential customers earlier in their buying journey.
In February 2025, TrackBee released a new integration with Klaviyo. This integration tracks more abandoned cart events on your website than Klaviyo does, triggering abandoned cart flows more frequently and generating additional revenue.
The timing of the release aligned perfectly with Zwarte Roes' email marketing improvement goals. Since they already had checkout abandonment flows live, they wanted to create new abandoned cart flows and measure TrackBee's impact.
After the integration's release, Zwarte Roes quickly expanded their email marketing strategy by implementing 2 new abandoned cart flows:
This approach allowed Zwarte Roes to directly compare performance and measure TrackBee's impact on their abandoned cart revenue. TrackBee should successfully capture abandoned cart events that Klaviyo's standard tracking pixel missed due to:
Zwarte Roes observed clear distinctions between their two abandoned cart setups within just 30 days of implementation.
TrackBee tracked 445% more abandoned cart events on zwarteroes.nl compared to Klaviyo alone.
TrackBee's server-side tracking captured more than four times more abandoned cart events compared to Klaviyo's standard tracking. This meant that hundreds of potential customer interactions that were previously invisible suddenly became actionable opportunities. For a specialty coffee brand like Zwarte Roes, each of these events represents a potential customer who showed genuine interest in their products.
TrackBee triggered the abandoned cart flow in Klaviyo 306% more times than Klaviyo would have done alone.
Because TrackBee captures significantly more abandoned cart events, Zwarte Roes' abandoned cart flow was triggered three times more frequently than with just Klaviyo. This increase meant their abandoned cart email flow was reaching way more potential customers at a critical decision point in their customer journey, which is crucial for generating additional abandoned cart revenue.
TrackBee generated 194% more abandoned cart revenue compared to Klaviyo alone.
And last but definitely not least, Zwarte Roes generated 194% more abandoned cart revenue with TrackBee than they would using only Klaviyo. This percentage represents recovered sales that would have otherwise been completely lost.
What's particularly noteworthy is that TrackBee's insights inspired Zwarte Roes to implement abandoned cart flows they didn't have before. This means they actually generated 293.5% more revenue than they would have without using abandoned cart flows at all. This fundamentally changed how Zwarte Roes approaches their email marketing strategy.
Marvin recognizes the value of recovering revenue that would otherwise be lost:
"It's not that we suddenly have double the overall revenue, but it's absolutely money that would otherwise be left on the table. And maybe it's also a good foundation, because you'll improve every month or year. As traffic grows and marketing budgets increase, having all these things set up properly becomes really interesting."
Zwarte Roes improved their email marketing strategy by implementing effective abandoned cart flows. By integrating TrackBee, they could measure the direct impact on results and generate significant additional revenue that would otherwise have been lost.
Next, Marvin aims to double Zwarte Roes' revenue in the coming year. With TrackBee as a strong tracking foundation in place, their marketing will only become more efficient. It's great to see the impact TrackBee makes in the short term, and we can't wait to see the results in the long term.
