“The transition process could not have been easier! The team at Alia was great at managing the process and worked with myself and our designer to make sure everything was looking and sounding like we wanted it to.”

Alia completely changed how we think about list growth. Their popups bring in high-intent customers we actually want to keep. We’ve seen a major lift in both email and SMS signups.

The Challenge

Low Opt-In Rates & No Intent Data

  • Klaviyo’s native popups stuck below 1% conversion (0.85%)
  • Opt-in growth lagged behind business growth rate
  • No zero-party data collection → limited ability to segment and personalize flows

“We just weren’t really growing our email list exponentially… it didn’t feel proportionate to the rate the business was growing. [...] Email is such an efficient and lucrative channel for us… we wanted to fill that funnel more.”
