Case Study: Hubble achieves 2.5x subscriber growth and lower CPA with Snapchat

Hubble doubles subscriber growth while cutting CPA

Hubble, a direct-to-consumer daily contact lens subscription service, turned to Snapchat to grow sign-ups for its two-week trial. Because contact lenses aren’t typically impulse buys and many customers convert across multiple sessions and devices, Hubble needed better measurement and ways to re-engage interested visitors.

By implementing the Snap Pixel to track the 28-day customer journey and using Pixel custom audiences plus lookalikes, Hubble re-engaged high-intent visitors with short, price-focused GIF-like ads and clear CTAs. The campaign drove 2.5x month-over-month subscriber growth, reduced CPA by 39% month-over-month and achieved an 82% lower CPA using Pixel custom audiences, enabling continued scale and nearly doubling quarterly Snapchat spend.
