Some campaigns perform well.
Others redefine what’s possible.
The Halloween launch campaign by Tates GmbH clearly belongs to the second category. 🎃👻
With a sharply focused WhatsApp campaign, the e-commerce brand achieved a 275.9x Return on WhatsApp Spend – proving the true power of permission-based messaging when strategy, timing, and technology align.
The challenge: a launch that needed attention – but with maximum efficiency
Halloween is loud, fast, and highly competitive.
For Tates, one thing was clear: if a seasonal launch was going to work, it had to deliver maximum relevance with minimal friction.
Instead of relying on crowded email inboxes or expensive paid ads, Tates chose a more direct path: WhatsApp – the channel customers use daily and open instantly.
The campaign goals:
- Maximum visibility in the shortest possible time
- Direct clicks to the shop
- Measurable revenue with minimal budget
The campaign: a Halloween launch delivered straight to the smartphone
The WhatsApp message was clear, perfectly timed, and sent to a highly relevant audience.
No unnecessary storytelling, no distractions – just an offer that was instantly understood.
The result: extreme attention and immediate purchase intent.
The results speak for themselves 📊
The performance of the Halloween campaign shows what’s possible when WhatsApp is used strategically:
- €13,238.12 WhatsApp revenue
- €47.99 WhatsApp costs
- 275.9x Return on WhatsApp Spend
- 68.1% click rate
- 22.6% conversion rate
- €136.48 average order value
👉 Each recipient generated over €30 in revenue on average.
👉 The message wasn’t just opened – it was clicked and converted.
Why this campaign worked so well
1. Relevance beats reach
The campaign was sent exclusively to users with an active WhatsApp opt-in.
Result: exceptional open, click, and conversion rates.
2. Timing beats frequency
Halloween is a clear buying moment.
The message arrived at exactly the right time – without spam or pressure.
3. WhatsApp as a true conversion channel
