Naväge + Cordero

On-Site Testing Delivers 10× Lift in Email Capture

Challenge:
Naväge sought to significantly improve email opt-in rates as the brand focused on building a scalable, high-quality subscriber base to support future lifecycle and campaign growth. Existing capture methods underperformed, and Naväge partnered with Cordero to maximize email acquisition through structured testing, holistic marketing integration, and campaign alignment.

Solution:
Cordero’s Lifecycle Marketing team designed and executed a multi-variant opt-in testing program using Klaviyo’s AI-driven capabilities.

Key initiatives included:

• Building and launching eight distinct newsletter popup variants, including basic popups, flyouts, teasers, seasonal themes, and incentive-based offers.

• Testing critical elements such as placement, copy, visual hierarchy, and incentive structure.

• Weighting each variant equally to ensure clean, unbiased test results.

• Monitoring unique views, submissions, and submit rates to identify the highest-performing configuration.

This approach enabled data-backed decision-making rather than assumption-driven design changes.

Results:

• 10× increase in submit rate from the winning popup variant.

• The top-performing experience combined a seasonal theme with a 10% incentive, driving materially higher engagement.

• Established a scalable opt-in framework supporting sustained, annualized list growth.
