Overview

The Austrian brand feschi Haircare has been consistently using WhatsApp as a performance channel for months — with remarkable success.
For their Halloween Special, the team led by Vanessa Danzinger once again demonstrated how to combine attention, excitement, and revenue in a powerful way. 🎃

With a creative pumpkin hunt, time-based surprises, and exclusive discounts, feschi achieved impressive results.

The Starting Point

feschi was looking for a channel that enables higher open rates, direct interaction, and more revenue per campaign than email or social media. At the same time, the setup needed to be fast, privacy-compliant, and free from complex tools.

The Halloween sale provided the perfect opportunity to activate the community in a playful way — while proving how strong WhatsApp performs for e-commerce.

The Flow of the WhatsApp Campaign

feschi executed the campaign in just a few steps:

  1. Define segment: active subscribers with high engagement
  2. Gamified message series: scheduled pumpkin drops at fixed times
  3. Discount & product logic: exclusive offers on popular haircare products
  4. Fast-lane checkout: direct link to a pre-filled cart
  5. Real-time optimization: adjusting CTAs & timings based on live analytics

The result: an organic mix of curiosity, urgency, and relevance that motivated the community to buy — without coming across as overly salesy.

What Other E-Commerce Brands Can Learn From This Case

WhatsApp isn’t a trend — it’s infrastructure

With over 90% usage in the DACH region, WhatsApp is the channel where customers expect brands to communicate.

Permission > Reach

A smaller, high-intent audience beats a large, unengaged list every time.
feschi is a perfect example of how powerful a high-quality WhatsApp base can be.

The ROI speaks for itself

An 18.1x return shows what happens when relevance, timing, and a high-performing platform come together.
