Why Chatarmin?

The Duschbrocken Story

Duschbrocken is the first solid 2-in-1 solution for skin and hair. Founded in 2018 in Stuttgart by Johannes Lutz and Christoph Lung after a shared trip around the world. The company has over 175,000 customers, around 20 employees, and is available at Rossmann, dm, and in their own online shop. They became known through Die Höhle der Löwen on VOX. 90% of revenue runs through their own online shop. Email and social media delivered solid results, but Duschbrocken wanted a channel that performs even more directly. A channel that lifts both reach and conversion in a single campaign. With minimal wastage.

“"WhatsApp performing almost as strongly as email for the first time, that really landed. We want more of that."”

How the campaign was built

Duschbrocken set up a WhatsApp sales campaign with Chatarmin, built directly around their own community. One campaign, one setup, one clear goal: revenue.

Campaign 1 The execution rested on three factors. Exclusive offers that motivate immediate action. Personal messaging through WhatsApp instead of crowded email inboxes. And optimised checkout links that make the path from click to order as short as possible.

Campaign 2

The campaign went out to Duschbrocken's existing WhatsApp subscriber base. Clear message, direct link to the shop, and an offer that fits the brand. The community knows Duschbrocken and trusts the brand. WhatsApp delivers exactly the closeness that translates that trust into conversion.
