Multi-Brand Consolidation Using Shopify Markets & Klaviyo: Key Considerations for Retailers

As multi-brand retailers scale, many are moving away from the friction of managing a web of independent Shopify stores, instead leveraging Shopify Markets to house multiple brands under a single, unified instance.

From an ecommerce management perspective, the appeal is clear. A single instance can reduce administrative overhead, simplify governance and create a more connected operating model across regions and brands.

However, consolidating your digital storefronts is only half the battle. To maintain a premium customer experience, you must effectively merge your communications without losing the distinct identity of each brand.

Done well, this can create a far more scalable and intelligent CRM ecosystem.

In this article, we’ll explore the main considerations for multi-brand retailers consolidating onto Shopify Markets, outlining practical ways to harness the power of Klaviyo for long-term success. We’ll look at ways to:

• migrate customer data effectively;
• structure your new CRM list;
• architect flows and automations;
• personalise emails; and
• manage reporting and attribution.

Building the right foundations when consolidating multi-brand CRM

For retailers managing multiple brands, one of the biggest challenges is deciding how customer data, lifecycle messaging and reporting should work once those separate stores become one.

Historically, each brand may have operated its own CRM and marketing automation account, complete with dedicated lists, segments, flows and reporting views. But in a consolidated Shopify Markets setup, those previously separate CRM environments need to be brought together too.

“Shopify Markets has opened up a really interesting question for multi-brand retailers: how do you consolidate your storefront without losing what makes each brand distinct? That same challenge plays out in CRM too. 

“Working with partners like Swanky, we’re helping merchants think through how to bring their customer data and automations together in a way that’s scalable, but still personalised at the brand level.” 

George Underwood, Enterprise Partner Manager, Klaviyo 

How you choose to set up your CRM will depend on your business model, internal team structure and the degree of separation between your brands. Some retailers will benefit from a highly centralised CRM setup. Others will need clearer brand-level distinctions within one account.

The important thing is to avoid creating a structure that becomes difficult to manage over time. Without the right foundations, merged accounts can quickly become cluttered, making segmentation, reporting and customer experience much harder to control.

Merging multiple Klaviyo accounts

Klaviyo offers a strong foundation for retailers looking to consolidate their stores because it integrates natively with Shopify and is designed to support sophisticated segmentation and lifecycle marketing workflows.

 “More and more EMEA retailers are managing multiple brands under one roof, and we’re seeing that reflected in how they’re using Klaviyo. The goal is always the same: one connected ecosystem that gives teams operational efficiency, without compromising the customer experience. Getting the data architecture right from the start is what makes that possible.” 

Diana Hayes, Head of Partner Marketing EMEA, Klaviyo

One of the advantages is that both Shopify and Klaviyo use email addresses as a key customer identifier. This makes it easy to unify customer profiles and maintain continuity of data as stores are brought together.

In most cases, the best approach to migration is to first consolidate your Shopify customer data, so that Shopify becomes the primary source of truth. Once that structure is in place, you can sync the unified dataset into Klaviyo and then migrate any additional profile data from legacy Klaviyo accounts via CSV import.

This approach helps ensure that the new account starts from a clean and consistent data structure, whilst still allowing Klaviyo to enrich profiles with any useful properties that may not already exist in Shopify.

When it comes to your flows and emails, you can clone these from your separate accounts into your new consolidated account, to avoid having to recreate them from scratch.

How to distinguish between brands within Klaviyo

One of the most common hurdles in a multi-brand setup is product differentiation. By default, external apps connect to the primary store’s product feed. This means Klaviyo may not automatically distinguish between “Brand A” and “Brand B” when pulling in catalogue data.

If you’re merging your Shopify stores into one, you’ll need to create your own way to bring your different Shopify feeds into third party apps such as Klaviyo. You can achieve this by creating a custom app that communicates with Klaviyo, checking for updates to product feeds and pushing these into Klaviyo as a custom product feed.

This is a critical step. If your Klaviyo account doesn’t reliably distinguish which brand a customer has browsed, purchased from or engaged with, it becomes much harder to deliver relevant messaging.

That in turn increases the risk of generic communications, inaccurate product recommendations and confused brand experiences.

At Swanky, we can help architect and implement bespoke solutions that allow retailers to retain brand-level precision inside a single Klaviyo account. If you need help setting this up, get in touch with our Klaviyo team.

How to structure list segmentation for multi-brand CRM

Once your data model is in place, the next question is how to organise your audience within Klaviyo. This merits careful planning, since how you structure your CRM will have a cascading effect on the rest of your Klaviyo account, impacting your flows, emails personalisation and reporting. What’s more, well-designed segmentation can have a significant impact on your email conversion rate.

Broadly, there are two routes available. Although there is no right or wrong answer, each approach has its strengths and weaknesses. The best approach for your business will depend on your internal team structure and business priorities.

Let’s unpack each option in more detail.

Option 1: Create a master list & segment within it

This is often the most streamlined and scalable approach, particularly for businesses with a centralised CRM or marketing function.

Under this model, customers join a single core list, and brand affinity is managed through segments, profile properties and behavioural data. Klaviyo is especially strong here, because its segmentation capabilities allow you to create highly targeted audiences based on purchase behaviour, browsing activity and custom fields.

The main advantage is control. A single list structure can make governance, consent management and campaign orchestration much easier to manage across the group.

However, there are a few considerations to take into account.

If a customer purchases from one child brand but has no relationship with the parent or sibling brands, your segmentation and content logic must ensure they only receive communications that make sense in context.

This is especially important for triggered flows. For example, a customer who abandons a cart on one brand store should never receive abandoned cart emails featuring another brand’s identity or products.

Similarly, where customers interact with multiple brands, you’ll need robust suppression and prioritisation rules to avoid duplicate or competing messages.

Finally, with a single master list, reporting can be complex, as we’ll discuss later.

Option 2: Create a separate list for each brand

For businesses with distinct brand teams, separate workflows and more autonomous operating structures, it may make more sense to maintain clearer separation within Klaviyo by allowing each brand to maintain its own dedicated list within the single Klaviyo account.

This can bring clarity from an internal management perspective. Teams can more easily own their audiences, build brand-specific campaigns and maintain reporting boundaries that align with how the business is run.

The trade-off is that list complexity increases. As customers move between brands, list membership and exclusion logic need to be managed carefully to avoid overlap, over-messaging or fragmented reporting.

Setting up Klaviyo flows for multi-brand accounts

When multiple brands exist within a single Shopify store, there is a real risk of triggering duplicate or misaligned automations if flows are not configured with the right logic. Events such as Added to Cart, Started Checkout or Placed Order are happening within one Shopify environment, so Klaviyo needs the right conditions in place to understand which brand context applies to each event.

Once again, you have two options for your flow setup.

Option 1: Separate flows per brand

By setting up individual flows for each of your brands, you can maintain greater autonomy for each brand over its communications, as well as allowing for more granular insight into the performance of each flow per brand, when it comes to reporting. This is great for larger teams, where multiple people may be responsible for communication.

However, separate flows do increase the risk of duplication if they are not tightly controlled. This happens because events – such as Added to Cart – are triggered on the single store and checkout, making it difficult for the system to distinguish which specific brand’s flow should be triggered. If there are multiple abandoned cart flows, the event could automatically trigger multiple abandoned cart emails to be sent from each of the brands. Therefore, you’ll need to create very specific rules for each flow to link them directly to the relevant product list.

In addition, keeping flows separate for each brand creates more assets to manage. You’ll want to ensure these are carefully tagged according to brand and divided into specific folders, allowing you to filter them more easily and quickly locate the correct flow.

Option 2: One central flow with segmentation

The alternative is to build a smaller number of core flows and then use conditional splits, dynamic content and segmentation to personalise the experience for each brand.

This can be a cleaner and lower-risk setup, particularly for events like abandoned cart or browse abandonment, where duplication is a common concern. A single trigger enters the customer into one controlled journey, and the email content adapts based on the brand context.

The challenge is that these flows can become large and complex. As more brands, teams and exceptions are added, they can become harder to maintain, test and report on.

In practice, the best answer is often a hybrid of both approaches. Some flows may benefit from centralisation, whilst others are better managed separately. Klaviyo is flexible enough to support either model, but success depends on choosing the right framework for the realities of your organisation.

Email personalisation

The goal of consolidation is efficiency, but it should never come at the cost of the customer experience. Once your segmentation and flows are set up correctly, the next focus is personalisation.

In the out-of-the-box setup, recommendation logic will default to the primary product feed, which can create issues in a multi-brand environment. 

To resolve this, you’ll need to build your own dynamic content blocks, tied to your brand specific product data. This allows each message to reflect the correct brand identity, merchandising logic and customer journey.

When implemented properly, Klaviyo becomes a very effective engine for this kind of personalisation, allowing brands to retain relevance even within a consolidated account. The important part is making sure the underlying data structure supports that outcome.

Reporting across multiple brands

Your reporting options depend on how you have chosen to set up your list segmentation and flow architecture.

If you’ve created separate lists and flows for each brand, reporting becomes much more straightforward at a brand level. You can compare automation performance, campaign revenue and engagement metrics with greater clarity, and spot differences between brands more easily.

If you’ve used a more centralised structure, reporting is still possible, but it tends to require more thought. You may be able to report cleanly on flows or campaigns overall, but breaking out performance by brand can become more dependent on filters, properties and consistent tagging.

This is not necessarily a drawback. For some retailers, consolidated reporting is actually a benefit, particularly where leadership wants a single view of CRM effectiveness across the business. But if brand-level insight is important, it needs to be designed into the account structure from the beginning.

This is often where specialist support adds real value. A well-implemented Klaviyo account should not only power strong customer journeys, but also give teams confidence in the data they are using to make decisions.
