Achieving Fast Growth Without Sacrificing Engagement Quality
Achieving Fast Growth Without Sacrificing Engagement Quality
In February 2023, ALDI Swiss launched its WhatsApp channel with the objective of building a high-quality subscriber base for weekly promotional messages. Starting from zero, the goal was to grow rapidly while ensuring open and click rates remained high.
The main challenges included:
Zero starting base – Acquire at the right cost: Scale quickly while keeping the cost per subscriber aligned with business targets.
Contests – Quality-focused mechanics: Define formats that attract relevant subscribers, not just prize-seekers.
Sustain engagement: Grow the subscriber base while maintaining strong performance for weekly marketing messages.

Combining Online Contests with Offline Raffle Campaigns
ALDI Swiss partnered with 360Dialog to implement a two-pronged subscriber growth strategy, leveraging both digital and offline channels.
Contests for Awareness and Lead Capture
Using 360Dialog's Contest module, ALDI Swiss ran seasonal campaigns with attractive prizes. The formats included quizzes, single-click "I take part" entries, and multi-winner giveaways, all promoted via Click-to-WhatsApp ads and organic entry points.
High-performing examples included:
Dyson Giveaway: +9% subscriber growth
Christmas Contest: +7% subscriber growth
iPhone AirPods Giveaway: +6% subscriber growth
Raffle Tickets Linking In-Store to WhatsApp
This approach required no paid media investment and ran entirely across ALDI stores. The process was simple: customers received a raffle ticket in-store, scanned a QR code, redeemed online, and opted in to receive an extra code via WhatsApp. Each redemption brought in a new subscriber at no extra acquisition cost.
Top results included:
Osterlösli: +18% subscriber growth
ALDIventskalender: +13% subscriber growth
