Challenge
For Easter, Bubbleroom wanted to try something more playful than their usual signup campaign. The goal was to increase engagement and boost email signups without changing the overall site experience too much.

How they did it
They created an A/B test using Triggerbee. Both versions were variants of the same digital egg hunt, where visitors had to find the pink egg.

In version A, users were told right away they’d get 20% off.

In version B, the reward was a mystery and users had no idea what they were getting until they won.

Only anonymous users saw the campaign, and it ran for one week.

The results
The mystery reward version won, and both variants drove nearly 20,000 signups in just one week which is a 2400% increase compared to their regular email sign up campaigns.

This quick test proved that adding a twist of gamification in combination with holding back the reward made users more likely to engage and submit their email.
