How G Fuel Drove 140% Increase in Signup Rate and 30% Increase in Post-Sign-Up CVR With Alia
G Fuel, a performance energy drink brand deeply embedded in gaming and creator communities, needed a better way to convert site visitors into owned audience members. With opt-in rates stuck around 5–6% using Klaviyo’s native popups, the brand was missing opportunities to capture valuable customer relationships.
After switching to Alia, G Fuel unlocked faster testing, smarter triggering, and interactive opt-in formats—resulting in dramatically higher signup rates and stronger downstream revenue performance.
The Full Story in 60 Seconds
They replaced our standard Klaviyo pop-ups. Since onboarding, we've 2-3x'd our signup rates, going from around 5% to consistently 12-14% on any given day. They're faster, more flexible from a design standpoint, and they let us iterate quickly on intro offers, which compounds over time.
CHALLENGES
Plateaued Opt-Ins, Slow Iteration, and Expensive Missed Capture
G Fuel wasn't struggling with traffic. The brand drives consistent volume to its site. The issue was what happened after visitors arrived.
At the time, G Fuel relied on Klaviyo popups to capture email sign-ups. Performance was stable, but it wasn't meeting expectations. Opt-in rates hovered around 5–6%, well below the team's internal goal of consistently exceeding 10%.
"It was okay, but not the place we want it to be, which is consistently above a 10% opt-in rate. Prior, we were only at 5–6%."
Limited iteration speed: Klaviyo's popup tools made it difficult to rapidly test intro offers and creative without slowing down execution.
Static triggering: Fixed trigger rules couldn't adapt dynamically to visitor behavior, capping the performance ceiling from the start.
Slow A/B testing: Running frequent, structured experiments required significant manual effort, making optimization reactive rather than systematic.
Revenue left behind: For a brand operating at scale, the gap between 5–6% and 10%+ opt-in rates represented tens of thousands of dollars in missed annual revenue — and a growing cost of repeatedly re-engaging visitors through paid channels instead of owned ones.
SOLUTION
Faster Testing, Smarter Optimization, and Continuous Improvement
G Fuel switched from Klaviyo pop-ups to Alia to improve how they tested, triggered, and optimized their opt-in experience. From day one, the biggest difference was speed.
"They're faster, more flexible from a design standpoint, and they let us iterate quickly on intro offers, which compounds over time."
Here's what made the difference:
With Alia, the team could A/B test intro offers more frequently, update creative without friction, and make design changes without slowing down execution — replacing the slow, manual iteration cycle that Klaviyo required.
Smart Testing enabled continuous experimentation across copy, design, and flow structure — surfacing winning variants faster and without constant manual oversight.
Smart Triggering moved beyond static logic, dynamically adjusting when and how popups appeared based on real-time visitor behavior and intent signals — improving engagement without requiring constant manual intervention.
The Scratch-Off format was one of the highest-impact experiments — an interactive offer that increased participation and lifted opt-in rate while staying aligned with G Fuel's brand standards.
Unlike the trigger-based tools G Fuel had used before, Alia moved beyond fixed logic — dynamically adjusting tests and triggers based on real-time performance and user behavior.
"We used tools that had some type of smart triggers, but they didn't really show as big of a lift. Alia measures and triggers dynamically while always learning."
Implementation was handled end-to-end through Alia's Fully Managed Plan, removing internal bandwidth constraints and ensuring insights from early tests were applied quickly and consistently across the signup experience.
With faster testing, dynamic trigger optimization, and fully supported execution, G Fuel built a more responsive opt-in system that improves performance over time.

Incremental Orders:
"If we do the math, that translated into 2.4x more purchases from email."
Additional Benefits
- Explosive Signup Growth: After launching with Alia, G Fuel's opt-in rate climbed from 5–6% to a consistent 12–14% daily — roughly a 140% lift — demonstrating both fast time-to-impact and sustained performance as testing volume increased.
- Stronger Post-Signup Revenue: The lift extended well beyond capture. Post-signup conversion rate improved by 30%, coupon redemptions approximately doubled, and email subscribers generated 2.4x more purchases — translating into tens of thousands of dollars in additional annual revenue without increasing traffic or ad spend.
- A System Built for Continuous Learning: Beyond raw growth, Alia gave G Fuel a repeatable framework for experimentation — allowing the team to continuously test, learn, and optimize without adding manual overhead. Instead of relying on one-off wins, the signup experience became a self-improving acquisition system that compounds performance over time.
"They replaced our standard Klaviyo pop-ups. Since onboarding, we've 2–3x'd our signup rates, going from around 5% to consistently 12–14%."
