Netlingeri Revives Dormant Customers With 6.39x ROAS
Email had gone cold - but Postbuddy helped Netlingeri revive thousands of lapsed customers with personalized, handwritten postcards. The result? A conversion rate of nearly 12%
In Denmark, folks from Jutland aren’t known for showing off. So when Henrik Christensen from Netlingeri.dk sent praise our way, it hit a little different. A classic DTC story: strong email flows, great customer base - but a big silent segment no longer engaging.
The Challenge
Netlingeri’s email marketing setup was already delivering, but a growing chunk of their audience had either lost permission or just stopped opening emails.
And when you're scaling fast, that adds up to thousands of unreachable, high-intent customers.
The Solution
They decided to test postcard marketing through Postbuddy - starting with a dormant segment that hadn’t purchased in over 12 months.
From kickoff call to campaign launch took less than a week:
Netlingeri handled the segmentation
We took care of the creative
The postcards were personalized and handwritten, making them feel like a true gift rather than just another ad. Now, Netlingeri is testing always-on flows and even expanding into new markets using the same approach.
The results
The numbers speak for themselves.
Postcards sent: 2,158
Conversions: 258
Spend: €3,068
Revenue: €19,599
ROAS: 6.39x
Conversion: 11.95%
Not bad for a shelved audience.
