TL;DR

The Full Story in 60 Seconds

Challenges

  • Email signup rates plateaued with their previous popup solution
  • Limited testing infrastructure made it difficult to run structured, high-velocity experiments or learn from performance data
  • Basic design editor restricted layout flexibility, content hierarchy, and interactive elements, making it hard to evolve beyond a single popup format
  • Lack of proactive support or managed testing, placing the full burden of optimization on the internal team and slowing iteration cycles
  • Static, one-size-fits-all experiences with little opportunity to educate visitors or adapt messaging dynamically

Solution

  • Migrated to Alia from their previous popup provider for smarter testing and optimization
  • Implemented full-screen, education-led popups with a mini-quiz
  • Used Smart Testing to experiment with copy, design, and flow structure
  • Deployed Smart Triggering to surface popups at peak intent moments
  • Captured email and SMS through separate, optimized steps

Results

  • Signup rate increased by 3x
  • +454% net new email subscribers vs. the previous period
  • +319% net new SMS opt-ins vs. previous period

CHALLENGES

Plateaued Signup Growth, Limited Testing & Low Support

Before switching to Alia, Four Sigmatic was using another popup solution to capture email and SMS subscribers. While the setup was functional, signup rates had plateaued, converting a tiny percentage of visitors into email subscribers. Incremental tweaks no longer produced meaningful lift, signaling that the existing approach had reached its ceiling.

Beyond raw conversion rates, the team faced structural limitations that made it difficult to improve performance over time. The previous tool's basic design editor limited flexibility in layout, content hierarchy, and interactive elements, resulting in largely static experiences that were difficult to evolve or tailor to different visitor contexts.

Testing posed another major constraint. Without support for structured, high-velocity experimentation, it was hard to run parallel tests, isolate learnings, or compound wins over time. Each iteration required manual effort, slowing down insight generation and making optimization reactive rather than systematic.

Ultimately, Four Sigmatic needed more than a tool to collect emails. They needed a popup experience built to scale learning, continuously improve performance, and support a more intentional, test-driven approach to owned audience growth.

The team's primary goals were to:

  • Break past existing signup ceilings and unlock incremental list growth
  • Experiment more aggressively with timing, design, and messaging
  • Move faster with structured testing, backed by clearer insights and learnings
  • Reduce internal overhead by getting stronger support for ongoing optimization and iteration

SOLUTION

A More Engaging, Educational Signup Experience

Four Sigmatic migrated to Alia with an initial focus on unlocking higher-intent engagement at the point of signup, not just increasing raw form fills. The goal was to turn the popup from a passive interruption into an interactive, educational experience that could adapt and improve over time.

"It was incredibly easy to switch over to Alia. The team had us up and running in no time."

Their early Alia setup prioritized:

A full-screen popup experience for higher visibility and clearer focus

A mini-quiz to boost engagement while collecting zero-party data

Customer education embedded directly into the popup flow, helping visitors understand product value before subscribing

A modern, visually engaging design with greater layout and content flexibility than their previous tool

Rather than relying on a single static popup, the team intentionally designed the experience to support rapid experimentation and continuous learning from day one.

From the start, Four Sigmatic ran multiple experiments using Alia's Smart Testing and Smart Triggering capabilities, enabling them to test and iterate without the manual overhead that previously slowed optimization.

They tested different aspects of the popup experience, including:

Popup copy and messaging

When and where the popup fired, based on visitor behavior and intent

Design elements and layouts, including step order and content density

Flow structure across steps, rather than treating the popup as a single moment

Email and SMS were captured through separate, sequential steps, allowing each channel to be optimized independently and reducing friction for first-time visitors.

In parallel, Alia's hands-on support and managed testing approach helped accelerate learning, ensuring insights from early tests were applied quickly and consistently across the signup experience without requiring constant internal intervention.
