OLAKALA® didn’t rely on one big discount message during Black Week. Instead, the brand ran multiple targeted WhatsApp campaigns, perfectly timed along the peak shopping phase. The result: measurable revenue, an exceptionally high ROI, and a channel that clearly performed while others were completely overcrowded.
The challenge: Black Week = peak attention overload
For most e-commerce brands, Black Week means one thing above all: overfilled inboxes and rising ad costs.
OLAKALA® faced the challenge of standing out despite massive promotional noise, without getting dragged into endless discount battles or diluting the brand. The solution: WhatsApp as a direct, personal sales channel – strategically orchestrated and technically scalable.
The strategy: Multiple campaigns instead of one big shot
Rather than putting everything into a single message, OLAKALA® opted for several WhatsApp campaigns throughout the entire Black Week.
The focus was on:
- clear messaging per campaign
- high relevance for subscribers
- a frictionless customer experience chatarmin provided the technical foundation: intelligent sending logic, GDPR-compliant opt-ins, clean tracking, and stable performance – even at high sending volumes.
The results: When relevance meets reach
The numbers speak for themselves:
