DR. VIVIEN KARL deliberately chose WhatsApp pre-access instead of mass discounts during the highly competitive Black Week – and turned exclusive proximity into measurable revenue. Even before Black Friday deals flooded every channel, WhatsApp subscribers received a time-limited head start with attractive benefits. The result: maximum attention, high purchase intent, and an exceptional return.
The challenge
Black Friday is loud, crowded, and expensive.
Email inboxes overflow, ad costs skyrocket, and discounts lose their impact. DR. VIVIEN KARL faced a challenge familiar to many premium brands: How do you create relevance and urgency – without diluting the brand?
The answer: pre-access via WhatsApp.
No mass channel. No wasted reach. Just direct, personal communication with customers who actively opted in.
The strategy: exclusivity beats noise
Instead of waiting for the official Black Friday kickoff, WhatsApp subscribers received early access to a limited offer:
- 20% discount on the entire assortment
- Valid even on already discounted products & sets
- Plus a free mini gift with every order
- Deadline until 11:59 PM
The message came directly from DR. VIVIEN KARL herself – personally worded, clearly structured, and optimized for conversion. Supported by a strong CTA and full transparency.
The results: when permission meets timing
The numbers speak for themselves and highlight the true potential of WhatsApp as a revenue channel:
- €6,936.16 WhatsApp revenue
- €40.83 WhatsApp costs
- 169.8x return on WhatsApp spend
- 86.1% open rate
- 49.5% click rate
- €80.65 average order value
One single campaign.
One clear pre-access advantage.
And one channel that delivers – without wasted reach.
