Stacked started as an online editorial site about real estate and evolved into a YouTube channel sharing some of Singapore’s most beautiful homes. After building up an audience of people who appreciate interiors and Stacked’s curatorial eye, they started Stacked Store, an online homewares store with a mission to elevate everyday living through beautifully designed, functional pieces.
Known for its minimalist aesthetic and thoughtful curation, the brand has built a loyal following across the region. Klaviyo has helped Stacked Store deliver personalised customer experiences since the ecommerce launch.

Challenge
Before launching its ecommerce store, Stacked used ActiveCampaign to keep in touch with their audience, but it lacked the ecommerce integrations the team would need to personalise communications with their customers, track performance, and drive revenue.
“Our customer’s experience with our brand is the backbone,” says Khalish Arsyad, marketing and creative lead at Stacked Store. “We don’t sell commodities, these pieces live in people’s homes or are thoughtful gifts. From the first email to unboxing their purchase, we want zero friction and we want to delight.”
Without a platform built for ecommerce, Stacked Store wouldn’t be able to target their messaging and create their desired customer experience. With the new venture, they needed a new email provider.
Solution
When Stacked launched their store, they made the switch to Klaviyo. “The event data, native Shopify integration, and revenue attribution made Klaviyo a different class altogether,” says Arysyad. “We plugged Klaviyo into Shopify in minutes and it just worked. We had flows with proven templates, purchase-centric analytics, product feeds, and clear attribution.”
With Klaviyo in place, Stacked started to build out flows to nurture and recover customers, and use segments to target campaigns based on region, engagement, product interest and more.
Strategy
Stacked Store’s lean team focuses on optimising repeatable formats and automations to drive sustainable revenue and relevance. In the first half of 2025, they saw 48x ROI and 25% of their total ecommerce revenue attributed to Klaviyo. They attribute their CRM success to:
- Weekly campaigns to drive newness without fatigue: Stacked Store use campaigns in Klaviyo to highlight best sellers, new arrivals, and curated roundups each week to maintain momentum between product launches. Customers receive updates based on region, engagement, and product preferences, ensuring communications feel personal and respectful.
- Automating the customer journey with flows: Khalish describes flows as “the workhorses” in Klaviyo, providing multiple touchpoints with customers and driving revenue as they sleep. Their two welcome flows alone drove 31% of their attributed revenue in the last 30 days.
Capturing high-quality leads with Klaviyo forms: By migrating their sign-up pop-up from a third party to Klaviyo forms, Stacked Store improved targeting and eliminated repeat prompts for existing customers. This has resulted in higher-quality sign-ups for Stacked Store and smoother experiences for customers.
There’s nothing like Klaviyo. We can see exactly which campaigns and flows move revenue, so iteration is fast and grounded in numbers, not feelings.
