Case Study: Hard Yakka boosts Black Friday sales with Andzen and Klaviyo

Hard Yakka boosts SMS ROI 8.5x YoY with Andzen

Hard Yakka, a legacy Australian workwear brand, needed a fast and personalized multichannel strategy to cut through the noise and drive action for their upcoming Black Friday sale. They partnered with the vendor Andzen and used the Klaviyo CRM and SMS platform to unify their email and SMS approach and better reach their diverse customer base.

Andzen implemented a full-funnel campaign using integrated lead generation, dynamic segmentation, and automated flows. This solution delivered high-impact, omnichannel messaging that removed friction for shoppers. The results were highly successful, including a 308% year-over-year increase in flow-attributed revenue and an SMS ROI of 8.5x, making it the brand's most successful Black Friday period on record.
