(Case Study – Black Week Launch 2025)
Overview
On the eve of Black Week, the chatarmin.com ecosystem achieved its highest single-day revenue ever recorded:
€3,128,423.63 – generated in just 24 hours – exclusively through WhatsApp.
What started as a scalable infrastructure for D2C brands has evolved into a high-performance communication backbone for hundreds of merchants across the DACH region. And at the start of Black Week, its full power became visible.
The Challenge
Black Week is both a logistical nightmare and a revenue machine. Organic reach drops, email lands in the promotions tab, and CPMs skyrocket.
D2C brands faced three core problems:
- High competition – Everyone is talking at the same time.
- Limited attention – Emails get ignored.
- Dependence on ads – Rising click prices destroy ROI.
The key question:
How can brands drive instant, direct, and measurable conversions — without relying on expensive ads?
The Solution: A synchronized WhatsApp launch powered by chatarmin.com
All participating merchants used chatarmin.com as the central hub for:
- Smart opt-in growth ahead of the event
- Precise segmentation and sending logic
- Automated send waves with failover mechanisms
- High-volume delivery stability
- Real-time click & commerce tracking
This turned WhatsApp into the “Revenue Engine Room” for Black Week.
