Personalization in ecommerce has been a priority for years. McKinsey's research shows that product recommendations, personalized email subject lines, dynamic homepage content — the tools have gotten sophisticated, and the expectations of customers have risen accordingly.
But most ecommerce personalization is still built on one data source: transaction history. What you bought, when you bought it, how often you come back.
In 2025, the merchants who will differentiate on customer experience are the ones who are adding a second data source: identity. Who their customers are — not just what they do.
This post explains why identity data is the next frontier in ecommerce personalization and what it looks like in practice.
The State of Ecommerce Personalization Today
Most Shopify merchants currently personalize based on:
Behavioral data: Purchase history, browse behavior, email engagement, cart activity. This data is rich, readily available, and well-supported by tools like Klaviyo and Shopify's native analytics.
Demographic data: Location, device type, acquisition channel. Useful for broad personalization but not particularly precise.
Stated preferences: What customers tell you they want — product categories, email frequency, communication preferences.
This is meaningful personalization. It is also the baseline. The merchants who are just doing this are keeping pace with expectations, not creating differentiation.
What Identity Data Adds to Personalization
Identity data is information about who a customer is in the world — their public profile, professional context, social presence, and influence. As Forrester has documented, this identity layer is becoming the new differentiator.
When you add identity data to your personalization toolkit, you unlock a fundamentally different tier of customer treatment:
Tier 1: Transactional Personalization (Current Baseline)
Tier 2: Behavioral Personalization (Good Standard)
Tier 3: Identity Personalization (The Frontier)
Tier 3 is not about automated email logic. It is about human-level attention, delivered at scale because you have the right data to know when it is warranted.
How Identity Personalization Works in Practice
At the Order Level
SonarID enriches every incoming Shopify order with identity data. When an influencer, celebrity, or notable professional places an order, you are alerted before the order ships — with enough context to personalize the experience meaningfully.
You know who they are. You know what their platform looks like. You know how to make their experience feel intentional rather than generic.
At the Fulfillment Level
Identity-informed personalization changes what goes in the box:
This is not automation. It is intelligent human attention, applied to the right orders because the right data told you which orders those are.
At the Relationship Level
Beyond the first order, identity personalization drives how you build relationships over time. The influencer in your customer base gets a different long-term communication track than the first-time buyer who is an everyday consumer. Not because they spend more — they may spend less — but because the potential value of the relationship is different.
Building an Identity-First Personalization Strategy
1. Install identity enrichment — SonarID on every incoming order
2. Define identity-based segments — influencers, public figures, investors, media
3. Build response playbooks per segment — what treatment does each identity segment receive?
4. Connect identity tags to your CRM — so communication flows can be triggered and maintained
5. Measure relationship outcomes — content generated, partnerships initiated, revenue attributed
The Competitive Advantage Window
Identity-based personalization is still early. Most Shopify merchants have not built it. The merchants who do build it now — before it becomes standard — will have a relationship moat that compounds over time: an authentic network of influencer advocates, genuine press relationships, and investor connections sourced organically from their own customer base.
That network is hard to replicate cold. It is easy to build from a strong identity-enrichment foundation. Neil Patel's guide to personalization confirms that the brands investing in deeper customer knowledge are seeing outsized returns.
