Sinsay

The Objective

Driving app growth with a performance mindset

Sinsay is a popular Polish brand offering not only affordable fashion, but also home decor, pet accessories, beauty products, and sports gear - making it a go-to for style and lifestyle in one place.

With this campaign, Sinsay aimed to increase ROAS by leveraging audiences from their always-on prospecting efforts while boosting retargeting and deep-funnel performance through their mobile app.

The Solution

Simplifying performance with Smart+ automation

Sinsay tapped into TikTok's Smart+ Catalog Ads for App - an AI-powered solution that automates optimization across targeting, creative, and delivery to drive results with minimal manual input. The campaign dynamically shifted budget to the top-performing formats, with catalog carousels emerging as the highest-performing creative type. This not only showcased the strength of catalog-based personalization but also streamlined operations, freeing Sinsay's team from time-intensive manual adjustments.

The Results

Results that reflect both fashion and function

By focusing on deep-funnel events and retargeting Android audiences, Sinsay’s Smart+ campaign reached peak efficiency. The results speak for themselves:

- 2x higher ROAS than manual non-catalog campaigns

- 2.5x higher CTR

- 153% uplift in revenue

With streamlined management and smart creative rotation, Sinsay proved that catalog-based automation can drive real business outcomes at scale.
