Choosing a Unified Data Platform Over a CDP to Scale Personalization
A Data Platform to Power AI-Driven Growth
The brand’s Vice President of Ecommerce partnered with Polar Analytics in late 2023 with a clear objective: build a reliable foundation for customer insights and prepare for AI-driven personalization. The brand had outgrown disconnected platforms and unreliable data latency. She explored options like CDPs and data warehouses but found them unnecessarily complex for the brand’s size and existing tech stack.
Polar offered a simpler path. Within minutes, the team connected Shopify, Klaviyo, Meta, Google Ads, and other key tools with no engineering required. Polar’s dedicated Semantic Layer consolidated this data, making ready-to-use metrics like LTV, retention trends, and cohort performance instantly available.
The Polar Pixel also enriched the dataset with accurate first-party tracking. Even during limited tests, the enriched data revealed patterns in purchase behavior, product preferences, and discount sensitivity. These insights helped the brand refine its merchandising and communication strategies.
With marketing, product, inventory, and customer data unified in one place, the brand established a clean, scalable foundation for AI-powered growth. This connected data environment set the stage for advanced email personalization.
Managing a High-Performing Email Channel Under Pressure
The brand’s email program was already a strong revenue driver, but as the brand grew, so did the complexity of keeping up with demand. The team was sending 3 to 4 emails per week with multiple layers of asset approvals, testing, and segmentation. The traditional “one and done” nature of campaign emails made it difficult to extend the value of high-performing content or create breathing room for the team to focus on long-term strategy.
Building an Evergreen, AI-Powered Email Program
The VP of Ecommerce was already a longtime Polar user when she connected with Bespoke AI through a trusted industry connection. The opportunity to integrate both services felt like a natural evolution in leveraging Polar’s clean, reliable data foundation to unlock AI-powered personalization.
What stood out was not just the AI-generated email scheduling and content adaptation, but the idea that an evergreen content library could continually engage audiences, adapt in real time, and ease the pressure of constant manual sends.
"I loved the idea of email staying alive in the world longer than one send. Especially if it’s performing well."
With the Polar Email Marketer, the team was able to:
- Automatically test subject lines (up to five variations at once).
- Personalize content delivery based on user behavior and purchase preferences.
- Send emails at the best possible time and day for each recipient.
- Keep high-performing content active longer, without manual effort.
It reimagines the idea that emails are only static blasts. They have become adaptive, optimized, and evergreen. For example, users who favor tops receive more top-related content, and those who didn’t open an email the first time may see it again 14 days later with a new subject line.
"We can now send the same email twice, with new subject lines and at different times, and no one notices. But performance improves."
Scaling Email into a 14.5% Revenue Channel with Self-Optimizing Campaigns
With Polar Email Marketer in place, the brand saw immediate, measurable improvements across their email program:
- Re-engaged 100,000+ dormant customers with personalized, AI-optimized content.
- Maintained list health, with unsubscribe rates increasing by only 0.3% despite audience expansion.
- Boosted email revenue, growing from an average of 11% to 14.5% of total revenue during non-launch periods.
Perhaps most importantly, the marketing team could finally step back from the daily pressure of building and sending emails. Evergreen content now runs in the background, adapting automatically, giving the team space to focus on launches and creative strategy.
"There was a real moment where I realized: if we don’t send an email tomorrow, Polar Email Marketer will still send one. And it will be beautiful."
What’s Next for the Brand
Looking ahead, the brand is deepening their focus on retention, customer re-engagement, and segment-level personalization. With Polar Email Marketer handling optimized email delivery, the team is now layering in more granular data strategies through Polar Analytics.
One of the key initiatives is building 90-day rolling KPIs to better track retention and spot potential churn. The team is working to identify which customers purchased within a recent 90-day period but have not purchased since, helping them understand gaps in the customer lifecycle and opportunities for timely re-engagement.
At the same time, they’re actively testing how different landing page experiences influence conversion rates.
"Bespoke x Polar gives us the confidence to rest, the data to experiment, and the structure to grow."
