Klaviyo wins for most UK Shopify stores

Klaviyo and ActiveCampaign are both serious email marketing platforms for businesses that have outgrown basic tools. They are designed for different primary use cases, which makes choosing between them less about feature comparison and more about understanding which fits your business model.

The short answer

Klaviyo is built for e-commerce. If your business is a Shopify DTC brand, Klaviyo’s Shopify-native integration, e-commerce automation library, and predictive purchase behaviour analytics are purpose-built for your use case.

ActiveCampaign is built for automation breadth and CRM. If your business has a B2B component, a sales pipeline that runs alongside your e-commerce, or you need the most flexible automation logic on the market, ActiveCampaign has capabilities Klaviyo does not.

Price comparison

Contacts	Klaviyo (Email)	ActiveCampaign Plus	Difference
Up to 500	~£20/mo	~£35/mo	AC +£15/mo
Up to 1,000	~£35/mo	~£49/mo	AC +£14/mo
Up to 2,500	~£60/mo	~£80/mo	AC +£20/mo

ActiveCampaign Plus pricing shown — the Starter plan is cheaper but lacks CRM and advanced automations that are usually the reason to choose ActiveCampaign over Klaviyo.

Klaviyo is cheaper at every tier. ActiveCampaign’s higher price reflects its CRM capabilities and broader automation logic. If you are not using the CRM, the price premium is hard to justify.

GDPR comparison

Klaviyo: EU data residency available at standard plan pricing — must be selected at account creation.

ActiveCampaign: EU data residency available on Enterprise plan only. Starter, Plus, and Professional plans store data in the US. This is the decisive GDPR disadvantage.

For UK stores on a budget of £50–100/month, ActiveCampaign’s EU data residency is simply not accessible. If GDPR data residency matters, Klaviyo is the better choice at standard pricing.

When ActiveCampaign wins

The automation builder is ActiveCampaign’s core advantage. Its conditional logic is more flexible than Klaviyo’s — you can build flows with arbitrary if/else branches, goal tracking, split paths, and multi-channel sequences that combine email, SMS, and CRM tasks. For businesses running complex nurture sequences — multi-month lead nurturing, sales pipeline automation, conditional B2B follow-up — this flexibility is worth the premium.

The CRM integration is the other differentiator. ActiveCampaign’s CRM is built into the same platform as email automations, so contact records, email engagement, and sales deal stages all sit together. For UK businesses that sell to both consumers and businesses (retail with a wholesale arm, for example), this removes the need for a separate CRM.

When Klaviyo wins

For a straightforward Shopify DTC brand, Klaviyo’s Shopify integration is in a different class. Real-time order sync, predictive CLV, browse abandonment tracking, machine learning product recommendations — these are e-commerce-specific features that ActiveCampaign’s Shopify integration does not match.

Klaviyo also wins on EU data residency at accessible pricing, which matters for UK stores where GDPR compliance is a priority.

Our verdict

Choose Klaviyo if your business is primarily DTC Shopify e-commerce. Choose ActiveCampaign if your business has a B2B or sales pipeline component that makes its CRM genuinely useful, and you can afford the price premium.

For the typical UK Shopify store reading this page, Klaviyo is the more appropriate tool. ActiveCampaign earns its place on this list for the specific profile of business it serves — but that profile is not the typical Shopify DTC brand.
