“The best part is we're maintaining our profit margins. We used to offer everyone a flat discount, and now we only give higher discounts when that's what's needed to make visitors sign in. It's a big win for us!”
The Challenge
JOLYN’s one-to-many popup strategy wasn’t converting visitors effectively and often gave away discounts that weren’t necessary, slowing list growth and hurting margins.
JOLYN’s list growth had stalled, limiting their ability to convert first-time visitors and build long-term customer relationships. With just a 3% email capture rate, most site traffic bounced without converting. Their universal 10% discount popup was easy to ignore and often gave away margin when no discount was needed to secure a signup.
More than just growing their list, JOLYN wanted to create a more personalized, intentional experience from the very first interaction. Their goal was to tailor each popup based on who the visitor was and what they were doing on the site in order to build stronger, more personal relationships from the start.
The Solution
JOLYN used AI agents to analyze real-time behavior and deliver personalized popups with the right message, timing, and offer for each visitor.
JOLYN replaced their static popup with a dynamic, AI-powered experience by integrating Monocle with Maestra’s marketing automation platform.
Monocle’s AI agents analyze real-time behavior, including purchase intent, exit signals, and engagement patterns, to decide when to show a popup and what incentive, if any, is most likely to drive a signup. Every popup is dynamically tailored to the individual, ensuring that each user sees the most relevant and compelling experience based on how they’re engaging with the site.
Each popup also captures zero-party data (like interest in beachwear vs. poolwear), allowing Monocle to personalize follow-up messages throughout the welcome journey and beyond.
“With this popup, we’re converting more website visitors into customers. People leave their email, get to know us through the welcome flow, start opening our regular campaigns, and they convert.”

The Results
The new popup strategy drove more email signups and increased revenue per user without relying on blanket discounts.
By replacing their one-size-fits-all discount with smarter, personalized experiences, JOLYN turned more visitors into subscribers, and more subscribers into customers. Best of all, they did it without sacrificing margin, setting a stronger foundation for long-term growth.
The impact extended beyond the initial signup. With richer zero-party data and higher-quality leads entering the welcome flow, JOLYN saw stronger funnel engagement including more email opens, higher click-throughs, and increased likelihood of first purchase. Personalization didn’t just boost the top of the funnel, it made the entire lifecycle more effective.
