How Tata Harper boosted sign-ups

Generated by Klaviyo AI

The article explains how Tata Harper Skincare used Klaviyo AI to test and optimize email and SMS sign-up forms after consolidating their tech stack. It details the AI-driven experimentation process that led to a 65%+ increase in form submissions within 30 days.

  • Unified tech stack: Tata Harper replaced siloed ecommerce, email, and SMS tools with Klaviyo to streamline customer data and marketing execution.
  • AI-driven form testing: The team used Klaviyo AI to generate and test 20 variations of sign-up pop-up placement and timing across desktop and mobile.
  • 65%+ submission lift: After implementing the winning AI-optimized forms, email and SMS sign-up submissions increased by more than 65% over the previous 30 days.
  • Centralized customer insights: Klaviyo now serves as Tata Harper’s central hub for loyalty, rewards, engagement, and subscription data.
  • Replicable approach: The case study outlines how other businesses can apply Klaviyo AI to improve sign-up form conversion rates.

Tata Harper Skincare is a pioneering, plant-based skincare brand. At their Vermont farm and lab, the team engineers bestselling formulas, from cleansers to face masks, using plants at peak potency. These ethically sourced products have helped Tata Harper create the luxury natural beauty category over the past 15 years—and redefine healthy skin.

Tata Harper’s siloed tech stack was holding their business back. But using different platforms for ecommerce, email, and SMS, they couldn’t operate in the same modern way their competitors did.

Each platform had its own functionality, which made it harder to create cohesive digital experiences for customers. Everything from marketing attribution to growing their subscriber list was clunky and complex.

Grow sign-up form submissions with Klaviyo AI

Switching to Klaviyo has empowered Tata Harper to test out innovative marketing strategies with ease, including using Klaviyo AI to test and optimize their email and SMS sign-up forms.

They tested 20 variations on placement and timing across their desktop and mobile sign-up pop-ups, all AI-generated based on their brand’s performance data.

In the 30 days after the winning versions went live, submissions for both forms jumped 65%+ from the 30 days prior to testing.

“Klaviyo has become this central point of reference for our customer data. Loyalty, rewards, engagement, subscription,” says Alexandra Barlowe, DTC email and SMS marketing director at Tata Harper. “I have all of that data at my fingertips.”
