The Challenge: Wunderkind Slowed Vessi's Growth
Wunderkilknd (Vessi's previous popup builder) slowed growth. Vessi faced:
- Weeks-long test cycles (mockups took up to 2 weeks).
- Flat popup conversions at 4–7% (peaked ~9% only during sales).
- Flow bias toward abandonment sequences, starving the welcome series.
- Rigid UX/logic (deeper tags like gender/preferences took months and failed).
- Needed a true growth lever—not just a form.
"It made agile testing impossible... We send a lot of traffic. But not being able to maximize that traffic, or the downstream LTV, was frustrating."

Interactive Popups Built to Convert
When they moved triggered emails (from Wunderkind) to Klaviyo, Vessi took the opportunity to upgrade their popups too, and chose Alia. With Alia, they were up and running in less than a day.
"It was the easiest implementation I've ever done. The Shopify app worked perfectly. And the team built everything so there was zero lag time."
Here's what made the difference:
Brand-led UX
Alia's popups felt intuitive and native to the website—no aggressive pressure tactics.
Information-first flows
Visitors were asked for shopping preferences before contact info, which Julien says helped ease friction and increase conversion.
Storytelling and segmentation
Alia allowed Vessi to educate users on the brand and offer contextual discounts while collecting data for segmentation on Klaviyo.
Zero bias
Unlike other platforms that prioritize their own email and SMS integrations, Alia gave Vessi full control over whether to prioritize email or SMS, without performance trade-offs.
A/B Testing Results
The team ran 7 A/B tests over three months, testing everything from delay timing and background imagery to smart triggers and education flows.
"With other tools, there's always a bias. They say 'do email with us,' and suddenly SMS performance drops. Alia doesn't push an agenda. It just helps you grow."

"We saw a 3x increase in coupon usage in just a few weeks. And we're finally capturing high-intent leads we can segment properly."
"The user experience just feels better. And it's easier for our teams to work with. Performance is high, but so are all the backend efficiencies."
"Our opt-in rates have tripled. Our SMS program is healthy again. And we're finally in control of how we grow our list—with no platform bias. Alia just works."
