A/B Testing Behavioral Nudges Led to 3X More Email Sign-Ups in 30 Days

Written By Mirna Salem

Client Overview
A health and wellness content platform offering digital courses and email-based programs struggled to grow its email list despite solid web traffic.

The Problem and Challenge
The email signup form had generic copy (“Subscribe for updates”) and was placed at the bottom of the page, with no psychological drivers to encourage signups.

NeuroNudge Solution
We created and tested three A/B variants using behavioral principles:

  • Loss Aversion Variant: “Don’t miss out on weekly tips to boost your energy — join 5,000+ subscribers.”

  • Social Proof Variant: Highlighted testimonials and subscriber count.

  • Reciprocity Variant: Offered a free mini-guide for signing up.

Results

  • Email signups tripled within 30 days.

  • The Loss Aversion variant outperformed the baseline by 206%.

  • Average time on page increased due to better engagement with the offer.

Client Quote
"We’ve been doing A/B testing for years — but this was next-level. NeuroNudge showed us the psychology behind the clicks."
