Initial Situation

Alpurial has been successfully using WhatsApp as a marketing and sales channel for some time – consistently delivering outstanding results.
The key question was: Can WhatsApp also generate strong ROI for high AOV (Average Order Value) products?

For Halloween, Alpurial launched a 10% discount campaign for their premium feed supplements.

Solution: WhatsApp Campaigns with Chatarmin

With Chatarmin, Alpurial was able to set up and launch the campaign within minutes:

Alpurial WhatsApp Marketing Case Study

  • Shopify integration ensured personalization and targeting at the product level.
  • Klaviyo integration enabled detailed CLTV cohort analysis (Email-only, WA-only, combined) – preventing cannibalization and proving true incremental uplift.
  • Multiple reminder campaigns within 24h ensured maximum reach – without incurring additional Meta costs.

The critical advantage: Chatarmin does not add any markup on Meta fees – giving brands a clear competitive edge during Q4.

Results

The Halloween campaign exceeded all expectations:

WhatsApp Pro Tip

Send multiple reminders within 24 hours to guarantee additional revenue without extra costs.
Thanks to Chatarmin’s pricing model, brands can fully leverage this arbitrage opportunity – at least until April 1, 2025, when Meta is expected to adjust its pricing.

Conclusion

Alpurial’s Halloween campaign proves that WhatsApp doesn’t just work for low-ticket impulse purchases but also for high AOV products.
By combining hyper-personalization through Shopify, incrementality measurement via Klaviyo, and efficient campaign execution with Chatarmin, Alpurial turned a seasonal promotion into a highly profitable growth driver.
