Klaviyo and Dotdigital both serve ecommerce brands, but they come from different worlds. Klaviyo was built from the ground up for ecommerce, with Shopify as its primary integration partner. Dotdigital (formerly dotmailer) grew from the UK's email marketing landscape into a broader omnichannel marketing platform that serves retail, B2B, and multi-channel brands. This different heritage shapes their strengths and weaknesses in ways that matter for your business.
For Shopify-focused DTC brands, Klaviyo is typically the default recommendation — and for good reason. But Dotdigital deserves consideration, particularly for UK-based brands, multi-platform retailers, and businesses with broader omnichannel needs. This comparison examines where each platform genuinely excels.
Having worked with both platforms for ecommerce clients, I can offer a practical perspective on the real differences beyond what each platform's marketing claims.
Platform backgrounds
Klaviyo, founded in 2012 in Boston, has grown into the leading email marketing platform for ecommerce. Over 150,000 brands use Klaviyo, predominantly Shopify stores. The platform's deep Shopify integration, ecommerce-specific automation, and transparent pricing have made it the standard recommendation in the Shopify ecosystem. Klaviyo went public in 2023, underscoring its scale and market position.
Dotdigital, founded in 1999 in London (originally as dotmailer), is one of the UK's oldest and most established marketing automation platforms. It rebranded to Dotdigital in 2019 to reflect its expansion beyond email into SMS, push notifications, live chat, and social advertising. Dotdigital has a strong European presence, is listed on the London Stock Exchange, and serves over 4,000 brands globally. It is a Shopify Plus Certified App Partner but also integrates with Magento, BigCommerce, and custom platforms.
Shopify integration
Klaviyo's Shopify integration is native and real-time. It syncs customer profiles, order history, browsing behaviour, product data, and back-in-stock notifications automatically. Klaviyo tracks on-site behaviour through its JavaScript snippet, enabling browse abandonment flows and real-time segmentation based on what customers are looking at right now. The integration is the foundation of Klaviyo's ecommerce value proposition.
Dotdigital's Shopify integration is functional but less deep. It syncs customer data, order history, and product catalogues. However, real-time browsing behaviour tracking requires additional configuration, and some Shopify-specific features (like Klaviyo's predictive analytics for individual customers) are not available through the Dotdigital integration. For brands using Shopify as their sole platform, Klaviyo's integration provides more actionable data.
For multi-platform retailers using Shopify alongside Magento, BigCommerce, or a custom platform, Dotdigital's broader integration support is a genuine advantage. Klaviyo integrates with other platforms too, but its deepest capabilities are Shopify-specific.
Automation and flows
Klaviyo's flow builder is purpose-built for ecommerce. Pre-built flow templates for abandoned cart, browse abandonment, post-purchase, winback, and welcome series provide quick wins. The flow builder supports complex branching logic, conditional splits, A/B testing within flows, and time delays. For a deep dive into essential flows, see our guide to 7 Klaviyo flows every store needs.
Dotdigital's automation — called "programs" — is powerful and flexible. The visual program builder supports multi-step journeys with conditional logic, wait steps, and channel switching (email to SMS to push notification within a single journey). Dotdigital's automation engine is not ecommerce-specific, which means it is more flexible for non-ecommerce use cases but requires more manual configuration for ecommerce scenarios that Klaviyo handles with pre-built templates.
For ecommerce-specific automation, Klaviyo is faster to set up and more intuitive. For complex multi-channel journeys spanning email, SMS, push, and web, Dotdigital's program builder is more versatile.
Segmentation and data
Klaviyo's segmentation leverages its deep ecommerce data. You can segment based on purchase behaviour, browsing history, predicted lifetime value, churn risk, product affinity, email engagement, and custom properties. Segments update in real time, enabling highly targeted campaigns based on the latest customer behaviour.
Dotdigital's segmentation is robust, supporting segments based on contact data, engagement, purchase history, and custom attributes. Dotdigital also offers a customer data platform (CDP) capability called Dotdigital CXDP, which unifies data from multiple sources for segmentation. However, for Shopify-specific behavioural data (like real-time browsing), Klaviyo's segmentation is deeper.
Email design and templates
Both platforms offer drag-and-drop email editors with template libraries. Klaviyo's editor focuses on ecommerce-specific blocks — product recommendations, dynamic content based on purchase history, and catalogue-driven layouts. Dotdigital's editor is polished and supports advanced personalisation, dynamic content, and A/B testing of design variations.
Both produce professional-quality emails. The practical difference is that Klaviyo's dynamic product blocks pull data from Shopify more seamlessly, while Dotdigital's editor is slightly more design-flexible for non-standard email layouts.
Omnichannel capabilities
This is Dotdigital's strongest differentiator. The platform natively supports email, SMS, push notifications, live chat, and social media advertising (Facebook and Google Ads audience sync) from a single interface. You can build customer journeys that span multiple channels — starting with an email, following up with an SMS, and retargeting with a social ad — all within Dotdigital's program builder.
Klaviyo supports email and SMS with expanding capabilities. For broader omnichannel orchestration, Klaviyo relies on integrations with third-party tools. If your marketing strategy requires coordinating campaigns across more than email and SMS, Dotdigital provides more native capabilities.
Pricing and transparency
Klaviyo's pricing is publicly listed and based on contact count. This transparency makes budgeting straightforward and comparisons easy. Prices scale from free (250 contacts) to enterprise tiers, with clear per-tier pricing.
Dotdigital's pricing is quote-based and not publicly listed. You need to contact sales for a pricing proposal, which makes comparison difficult. Dotdigital is generally positioned as a mid-market to enterprise platform, and pricing typically starts higher than Klaviyo for equivalent contact counts. For smaller brands, Klaviyo's accessible entry point is a significant advantage.
Analytics and reporting
Klaviyo provides ecommerce-specific analytics — revenue per campaign, revenue per flow, customer lifetime value, and predictive analytics. The dashboard focuses on metrics that matter for ecommerce businesses, with clear attribution of email and SMS revenue.
Dotdigital's reporting covers email performance, automation program analytics, and cross-channel engagement. The reporting is comprehensive for marketing performance but less ecommerce-specific than Klaviyo's. For broader ecommerce analytics, see our analytics setup guide.
Deliverability
Both platforms maintain strong deliverability reputations. Dotdigital has a particularly strong reputation in the UK and European market, partly due to its long history and relationships with UK ISPs. Klaviyo's deliverability is equally strong globally. Both provide authentication (DKIM, SPF, DMARC), dedicated IP options, and deliverability monitoring tools.
GDPR and compliance
As a UK-headquartered company, Dotdigital has GDPR compliance deeply embedded in its platform. EU and UK data hosting options, consent management tools, and compliance features are native and well-implemented. Dotdigital is ISO 27001 certified and compliant with UK data protection regulations.
Klaviyo is GDPR-compliant and offers EU data hosting. However, as a US-based company, some UK brands prefer the additional assurance of a UK-headquartered platform with UK-based data centres. For brands with strict data residency requirements, this can be a differentiating factor.
Support and resources
Dotdigital provides UK-based support, dedicated account management on higher tiers, and a strategic services team that can assist with campaign strategy and implementation. The UK-based support is a practical advantage for UK brands in terms of timezone and cultural alignment.
Klaviyo provides email and chat support with a large knowledge base and community. Higher-tier plans include dedicated customer success managers. The community of Klaviyo users and partners is significantly larger, meaning peer support and third-party resources are more abundant. For our Klaviyo services, we provide hands-on strategic support.
