Every customer transaction tells a story. But for most retailers, that story ends at the checkout counter.
A customer enters your store, browses, completes a purchase, and leaves. Their email is captured, loyalty points are updated, and the transaction is recorded. Yet, without further action, all this valuable data remains untapped.
That valuable customer data sits silently in your POS system, disconnected from the marketing tools that could turn a one-time buyer into a loyal, repeat customer.
You're collecting rich customer data every day, including purchase history, product preferences, and spending patterns, but without a bridge to your marketing platform, that data remains trapped, underutilized, and invisible to the teams who could act on it.
Each transaction creates data: actionable information about who your customers are, what they buy, and how they engage with your brand. Yet for most retailers, this data remains fragmented. The in-store purchase lives in your POS system. The online order sits in your ecommerce platform. The loyalty activity is recorded somewhere else entirely.
Your marketing team sends email campaigns to broad lists because they can't segment based on recent in-store purchases. They miss opportunities to re-engage customers who haven't shopped in months because they can't see both online and offline activity. They measure campaign success by open rates and clicks, unable to connect marketing efforts to actual revenue generated at the register.
This disconnect is not just frustrating; it is costly. Marketing dollars lose impact when data is incomplete. Customer relationships weaken without recognition across channels, and opportunities to personalize, surprise, and delight are lost before they even start.
The difference isn't better marketing, it's better integration.
That's why Eurostop has partnered with Klaviyo.
Klaviyo is the leading customer data and marketing automation platform, trusted by over 193,000 businesses worldwide to deliver intelligent, personalized communications. By integrating Eurostop's retail management system with Klaviyo, we create a seamless bridge between your store operations and your marketing engine, turning every transaction into the beginning of a meaningful customer relationship.
Because in modern retail, the brands that win aren't necessarily those with the biggest marketing budgets. They are the ones who know their customers best and use that knowledge to communicate smarter, not harder.
How Klaviyo Works with Eurostop
The Eurostop + Klaviyo integration connects your POS system, eCommerce store, and CRM data to create a fully unified marketing ecosystem. This allows retailers to automate campaigns, personalize messaging, and make data-driven decisions effortlessly.
Once the data reaches Klaviyo, it becomes the foundation for sophisticated marketing capabilities:
1. Unified Customer Data
Every customer automatically receives a comprehensive profile that combines their online and offline activity. Within Klaviyo, you can see at a glance:
- When a customer first shopped with you, and in which store
- Their complete purchase history across all locations and channels
- Their preferred products, categories, and average order value
- How recently and how frequently they've engaged with your brand
- Their loyalty status and points balance
- Any returns or issues they've experienced
This 360-degree view transforms anonymous shoppers into recognizable individuals, enabling genuine personalization at every touchpoint.
2. Advanced Customer Segmentation
With rich customer profiles in place, you can build highly targeted segments based on any combination of online and offline behavior.
For example:
Customers who purchased a specific product in-store but haven't bought online
High-value shoppers who haven't visited any location in the last 90 days
Loyalty members who consistently shop at one store but never another
Customers who bought winter coats last season may need a new one soon
Shoppers who made their first in-store purchase within the last 30 days
These segments update automatically as new data flows in, ensuring your campaign always reaches the right audience without manual maintenance.
3. Automated Marketing Flows
Klaviyo's true power lies in its ability to trigger personalized communications based on customer actions. Such as:
Trigger: First in-store purchase
Automated Flow: Welcome series introducing loyalty program and brand story
Trigger: High-value purchase
Automated Flow: Thank you message with complementary product recommendations
Trigger: Birthday month
Automated Flow: Special discount redeemable at any location
Trigger: Loyalty points earned
Automated Flow: Points balance update with suggestions for redemption
Trigger: Post-purchase moment
Automated Flow: Cross-sell or upsell recommendations based on items just bought
Trigger: Return processed
Automated Flow: Follow-up ensuring satisfaction and offering assistance
Trigger: Cart Abandoned (Online)
Automated Flow: Reminder to complete purchase with items saved
Trigger: Anniversary of first purchase
Automated Flow: Celebration offer marking their customer milestone
Trigger: 90+ days since any activity
Automated Flow: Win-back campaign with compelling incentive to return
Each flow is fully customizable, letting you craft the right message at the right time for the right customer based on their actual behavior.
4. Insights & Analytics
Perhaps most powerfully, the integration enables true omnichannel measurement. When you send an email campaign, you can see not only who clicked and purchased online, but also which customers visited your stores and made purchases as a result.
Klaviyo's revenue attribution tools track:
- Online sales directly from email clicks
- In-store sales from customers who received the campaign
- Overall campaign ROI combining both channels
- Marketing touchpoints influence long-term customer value
This complete picture transforms marketing from a cost center into a measurable growth driver, with clear visibility into what's working and what isn't.
Client Case Studies
See how retailers are leveraging this integration in action.
Benjamin Barker
Benjamin Barker is an established men’s clothing brand with both retail boutiques and an online store. Through the Eurostop + Klaviyo integration, the brand now leverages real-time transaction data to build structured customer journeys based on wardrobe behavior and buying patterns.
By analyzing purchase categories such as formalwear, business attire, and casual collections, Benjamin Barker can identify customer style preferences and buying cycles. For example, customers who purchase suits are automatically entered into follow-up flows featuring matching shirts, ties, and accessories. Seasonal launches are promoted selectively to customers whose past purchases align with new collections, ensuring communication remains relevant rather than promotional.
1855 The Bottle Shop
1855 The Bottle Shop is a premium liquor retailer serving both walk-in customers and online buyers. Liquor purchasing behavior differs significantly from fashion retail, often revolving around occasions, gifting seasons, or limited-edition releases. With unified omnichannel data, 1855 The Bottle Shop can now track purchase history and buying patterns in real time, enabling more relevant and timely communications.
The brand leverages this insight to deliver personalized recommendations by suggesting products based on past purchases, such as highlighting complementary spirits or popular collections. Automated flows also allow the retailer to re-engage customers who haven’t purchased in a while, sending tailored reminders or promotions aligned with their preferences.
By connecting real-time retail data with automated marketing, 1855 The Bottle Shop drives repeat purchases and enhances loyalty while ensuring communications remain relevant and meaningful across both physical and online channels.
