4,450 emails in 7 days with Black Friday spin-the-wheel popup — WHOSE

The challenge

For Black Friday 2024, the team was looking for a way to stand out. The challenge wasn't just to grab emails — it was to make the experience feel more like a game.

The solution — a wheel that actually got people spinning

The idea was simple:

• The wheel appears a few seconds after someone lands on the site.

• The user enters their name and email.

• Then spins the wheel to get a surprise reward.

• Right after spinning, the user sees a unique promo code directly in the widget.

How the widget was built

What they customized:

• Added a name field for personalization.

• Enabled a checkbox for GDPR consent.

• Swapped background imagery to match their brand.

• Changed the wheel and button colors.

Results and business impact

They saw a conversion rate of up to 50% — a massive leap from their usual 3–5%. Around 30% of new subscribers actually used their discount and completed a purchase.

Why gamification wins during seasonal sales

Claspo's gamified widget gave users a small dopamine hit, a feeling of luck, a reason to stay. The experience shifted from 'join our list' to 'you just won something'.
