That was exactly the challenge Gratsi brought to us.
Gratsi is a wine subscription brand with a strong product and a growing customer base. Their problem was not acquisition. It was what happened AFTER the first purchase. A significant portion of customers were buying once and never converting to a subscription.
Our hypothesis was that messaging was the lever.
Every customer, regardless of who they were or why they bought, was receiving the same campaign. Different people have different motivations, different objections, and different reasons to subscribe. If we could speak to each of those individually, we believed conversion rates would improve.
So we ran a test to find out whether the right message, sent to the right person, could convert more one-time buyers into subscribers.
Most email platforms are built on behavioral data: purchase history, browsing activity, and email engagement. These signals tell you what a customer has done. They do not tell you:
or
To go deeper, we integrated OuterSignal’s personalization technology into Gratsi’s email program. Using demographic and psychographic data, it analyzed the customer base and generated four distinct personas:
Each persona was built around a detailed profile using:
Every customer in the database was automatically assigned to one of these four personas, enabling a level of segmentation that no email platform alone can produce. We then developed unique messaging for each segment, tailored to the specific motivations and decision-making drivers of that profile.
Rather than sending a single message that partially addresses everyone, each persona received content that spoke directly to who they are and why Gratsi’s subscription model was relevant to their life.
We ran the experiment across a large portion of Gratsi’s list, structured as a controlled A/B test:
The primary success metric was the rate at which one-time customers converted to active subscribers, with all secondary metrics tracked in parallel.
The personalized group produced significantly more active subscribers than the control. In a subscription business, incremental subscriber growth at this rate has a compounding effect on long-term revenue.
A second test confirmed the same conclusion: personalized messaging consistently converts more customers than a one-size-fits-all approach.
With two tests validating the approach, the next phase for Gratsi is extending psychographic personalization across the full customer lifecycle.
If you have a customer base full of one-time buyers who never converted to subscribers, the opportunity is in getting the right message to the right person. We will:
