The brief.
Lindner & Co runs a separate store and list in each country. After a strong winter the lists were tiring: unsubscribes were high in Denmark, revenue was sliding in Sweden, and the client judged email on its own attribution tool, which credited it with far less than Klaviyo did.
Our approach.
We put a sunset flow live in every market, moved campaigns back to engaged subscribers and built a welcome path for each product. When the client turned on paid and influencer traffic in May, those welcome flows were where the new subscribers landed. In July we built the email program for a new English and French store from scratch.
The results.
Klaviyo campaign and flow reporting for each market’s own account, in that market’s currency, beside the email revenue reported by the client’s own attribution tool, Triple Whale. The two count differently and are never added together. Store revenue is Klaviyo’s count of all orders placed.

A closer look at the work.
From April to June 2026 email revenue went from 45,295 to 150,864 NOK in Norway, 85,855 to 285,122 SEK in Sweden and 29,813 to 148,045 DKK in Denmark. The client’s own tool showed the same shape: 3.5, 3.5 and 4.4 times. Through a slow summer Norway’s email held about 17% of store revenue, and the new international store’s email grew from $7,007 in July to $16,460 in the first 28 days of September.
