Black Week is competitive, loud, and expensive.
Email inboxes are overflowing, paid ad costs are skyrocketing – yet customers still expect personal, relevant communication.
In November, VITAFORM deliberately chose a channel that creates closeness instead of burning reach: WhatsApp.
With a clearly structured presale strategy, exclusive access, and perfect timing, WhatsApp became the strongest performance channel of the entire Black Week.
The result: 40.7x Return on WhatsApp Spend – during the most important sales phase of the year. 💥
The challenge: Black Week without wasted reach
Instead of launching all offers at once, VITAFORM opted for a Black Week presale:
- Early access exclusively for WhatsApp subscribers
- Exclusive content and clear advantages
- Scarcity instead of mass discounts
The goal: activate high purchase intent before the real Black Week noise even begins.
The strategy: Presale instead of a price war
Together with chatarmin, VITAFORM built a setup focused on relevance, speed, and control:
- Segmented WhatsApp list with explicit permission
- Presale access via password directly inside the message
- Mobile-optimized, conversion-focused call-to-actions
- Full transparency across revenue, costs, and performance
WhatsApp wasn’t treated as a “newsletter replacement” — but as a direct sales channel. And used exactly that way.
The results: WhatsApp as a revenue driver in November
The numbers speak for themselves:
- €48,792 WhatsApp revenue
- €1,200 WhatsApp costs
- 40.7x Return on WhatsApp Spend
- €144.07 Average Order Value
- 5.18% Conversion Rate
Especially compared to classic paid channels, one thing becomes clear:
WhatsApp doesn’t just perform more efficiently — it performs highly profitably.
Why WhatsApp works so well for VITAFORM
This success wasn’t a coincidence. Three factors made the difference:
1. Context beats creativity
Customers knew why they were receiving the message — and what was in it for them.
2. Proximity drives purchase decisions
WhatsApp feels personal. That trust directly increases conversion rates.
3. Technology that doesn’t slow you down
With chatarmin, the entire presale ran smoothly, measurably, and at scale — without operational friction.
The takeaway: Black Week performance without budget explosion
VITAFORM proves how modern e-commerce works today:
Not louder, but smarter. Not broader, but more relevant.
WhatsApp evolved from a communication channel into a revenue-generating infrastructure — delivering an ROI that traditional channels can barely reach in November.
The right partner makes the difference
Setting up WhatsApp marketing properly is complex.
With chatarmin, it becomes a competitive advantage that translates directly into revenue.
