Making email required to see Bike Finder quiz results lifted unique email captures at The Pro's Closet by 49%, with no impact on purchases. Surefoot ran this A/B test for the used-bike marketplace and published it as a case study. Before the test, email was optional.

## Result

**+49% email captures**

- Unique email captures: up 49%.
- Purchases: no impact, so the gate did not cost sales during the test.
- The case study reports the lift as significant.

## Control

The Bike Finder quiz let visitors skip the email step and still see their bike matches.

## Variant

Visitors had to enter an email address to view their quiz results.

## Why it likely won (our reading)

- Visitors who finished the quiz had already invested time, so most were willing to trade an email for the answer.
- The email was tied to something they wanted, their matched bikes, not a generic newsletter.
- Bike buyers often research for months, so many were happy to stay in touch.

## Caveats

Sample size and duration were not shared. The 100,000+ emails figure covers the whole quiz program over nine months, not this test alone.

## How to run this test

- Hypothesis: If we require an email address to see quiz results, then we will capture more emails without losing sales because visitors who finish the quiz want their results enough to share an address.
- Primary metric: Unique email captures
- Guardrail: Quiz completion rate
- Guardrail: Purchases from quiz takers
- Guardrail: Email unsubscribe or bounce rate
- Who should test it: Stores with a product finder or quiz and a long buying cycle, where email follow-up drives later sales. It may hurt where shoppers want a quick answer and buy right away.
