With TrackBee, HappyFlops solved two problems at once. Their paid channels now run on reliable, server-side conversion data that feeds directly back into Meta, TikTok and Google – helping algorithms optimise properly. At the same time, their Klaviyo setup finally captures all abandonment events, turning missed opportunities into measurable revenue.

HappyFlops is a slipper brand that’s scaling fast, founded by Santiago. After a personal discovery - walking countless hours through his house with his newborn, realizing his knee pain disappeared when wearing the slippers he’d been testing, HappyFlops grew from a side project into a thriving international brand.
From their home market in Sweden, the brand expanded to The Netherlands, where co-owners Jesse & Ryan helped rapidly scale sales through influencer marketing and sharp e-commerce execution. Within months of launch, HappyFlops grew very fast in the Dutch market.
Behind that success, however, hid a major challenge: their tracking setup was failing – and costing them revenue.
Before working with TrackBee, HappyFlops struggled with unreliable tracking data across their entire marketing setup. Running ads on Meta, TikTok, Google, and Pinterest, the team saw the same order being claimed by multiple platforms. Sales attribution was inflated across the board, and their omni-channel ROAS became difficult to calculate.
“We knew the numbers weren’t right,” Jesse says. “Every platform claims every sale. And that leaves you blind when you’re deciding where to scale or where to cut.”
In an attempt to solve the issue, HappyFlops tested server-side tracking through Triple Whale. While this initially seemed like a step forward, it soon became clear that Triple Whale didn’t solve their core problems. Most critically: the conversion data Triple Whale collected wasn’t sent back to ad platforms – meaning algorithms couldn’t optimize based on real outcomes.
"We missed that feedback loop. Meta just wasn’t learning properly.”
To regain control over their data, HappyFlops first implemented TrackBee across all their paid channels. From that moment, performance started to improve. With TrackBee’s server-side tracking in place, conversion data from Meta, TikTok, Google, and Pinterest wasn’t just visible in dashboards – it was actively sent back into the ad platforms themselves. Algorithms could finally optimize on real, verified purchases.
“Installing TrackBee was simple,” Jesse says. “But what really made the difference is that conversions started feeding back into our ad accounts. That’s where we saw campaigns perform better.”
Where their previous solution, Triple Whale, only improved reporting, TrackBee directly impacted results by closing the feedback loop between sales and marketing platforms.
Later, when TrackBee’s Klaviyo integration became available, HappyFlops activated it without hesitation.
“We had no idea Klaviyo misses so many events. TrackBee showed us we were leaving serious money untouched.”
Like many brands, HappyFlops relied on Klaviyo for retention marketing, but they didn’t realize Klaviyo wasn’t receiving all their customer data.
Because many browse abandonment and abandoned cart events weren’t being tracked, fewer email flows were triggered - causing HappyFlops to miss out on significant revenue opportunities.
By feeding enriched server-side session data directly into Klaviyo, all browse abandonment and abandoned cart events now trigger correctly. Instead of missing events due to Klaviyo’s inaccurate tracking, every abandonment moment is captured – and every email flow gets triggered as it should.
“We didn’t change anything in our Klaviyo flows, we just started tracking the right data. That alone unlocked $88.000+ in extra revenue in just a few weeks.”
Since integrating TrackBee, HappyFlops has seen improvements across every key metric in their email funnel:
More tracked abandonment events
By adding TrackBee’s server-side tracking, HappyFlops uncovered a huge volume of abandonment events that Klaviyo’s standard setup failed to capture.
More flows triggered
Thanks to TrackBee’s server-side data, HappyFlops saw a dramatic increase in the number of abandonment flows actually being triggered.
In other words: TrackBee more than doubled the number of abandonment flows triggered, without changing anything in Klaviyo itself.
Significant extra revenue unlocked:
By simply feeding better data into existing flows, HappyFlops generated measurable extra revenue:
$30,024.09 (€27,294.63 )in additional revenue via their Added to Cart (TrackBee) flow.
$59,570.29 (€54,154.81) in additional revenue via their Browse Abandonment (TrackBee) flow.
Combined, that’s over $89,000 in additional revenue – without writing a single new email.
“All of this was hidden revenue,” says Jesse. “We were running those flows before, but Klaviyo wasn’t seeing the missing events.”
