Case Study: Kapten & Son grows its WhatsApp audience and boosts flash sale revenue with Charles GmbH

Kapten & Son drives 20k WhatsApp opt-ins with Charles GmbH

Kapten & Son, an innovative fashion brand, wanted to find a more personal and effective way to communicate its popular special discounts and test WhatsApp as a long-term revenue driver. Their challenge was to move beyond less flashy sales and prove the value of the WhatsApp channel for their business in time for Black Friday. They partnered with Charles GmbH, using its platform to implement WhatsApp marketing solutions.

Charles GmbH implemented a solution featuring a website sign-up flow for exclusive sale access and an automated double opt-in process to ensure quality subscriptions. The results were highly successful. Kapten & Son gained 2,000 WhatsApp opt-ins in the first 48 hours and achieved a 92x ROI with €14.85 revenue per recipient in an initial flash sale. Most significantly, they met their Black Friday goal of collecting 20,000 subscribers, building a substantial audience for future revenue growth.
