Independent comparison for enterprise buyers. Updated April 2026.
Quick verdict: Klaviyo is the better fit for ecommerce and B2C brands that need email, SMS and behavioural personalisation tied tightly to store and customer data. Oracle Eloqua is the stronger choice for large B2B enterprises that need lead and account scoring, campaign orchestration and integration with Salesforce or Oracle CX. The key differentiator is market: Klaviyo optimises for transactional B2C engagement, Eloqua optimises for long-cycle B2B demand generation, and the two rarely compete for the same buyer.

Klaviyo is a B2C engagement platform built around ecommerce data. It ingests order, browsing and event data from platforms such as Shopify, BigCommerce and custom stores, and turns it into behavioural segmentation, abandoned-cart and post-purchase flows, predictive metrics like estimated customer lifetime value, email, SMS, mobile push and reviews. Its growing customer-data capabilities let brands unify profiles and act on them without a separate stack, which is why direct-to-consumer retailers favour it.
Oracle Eloqua is an enterprise B2B platform focused on the opposite motion: capturing leads, scoring them by behaviour and account fit, nurturing them through the Campaign Canvas, and routing qualified leads to sales in Salesforce or Oracle CX. Its strengths are progressive profiling, custom data objects, account-based marketing and orchestration across long buying cycles involving multiple stakeholders, where revenue depends on sales follow-through rather than direct online purchase.
These products are built for different revenue models. Klaviyo excels where a customer can buy directly and behaviour drives messaging; Eloqua excels where a sales team closes complex deals and marketing must qualify and orchestrate demand. Using either outside its intended motion produces a poor fit, so the comparison is mostly about confirming which model applies.
Klaviyo prices on active profiles, a model adopted in 2025 that bills on profiles you store and engage rather than total contacts. Email plans start around $20 per month and Email plus SMS around $35 per month at the entry tier, scaling to roughly $150 per month at 10,000 contacts and into the thousands at larger lists, with SMS credits and add-on products affecting the total. Enterprise pricing is custom. The model is transparent and self-serve at smaller scale.
Oracle Eloqua is sold through Oracle with contact-based tiers; third-party estimates put Basic near $2,000 per month and Standard near $4,000 per month for roughly 10,000 contacts, with Enterprise quoted individually, plus implementation and integration costs. Eloqua's pricing reflects an enterprise B2B investment and a managed sales process, in contrast to Klaviyo's published, usage-based ecommerce pricing.
Klaviyo is self-serve and typically live within days to weeks once the store integration and flows are configured, fitting B2C teams without heavy marketing operations. Eloqua is a multi-month enterprise deployment involving data integration, lead-scoring design and CRM alignment, usually with a partner. Klaviyo fits brands whose growth depends on direct-purchase behaviour; Eloqua fits enterprises whose growth depends on qualified pipeline handed to sales.
Klaviyo's ecosystem centres on ecommerce: deep native integrations with Shopify and other storefronts, payment and review tools, and an API for custom events. Eloqua sits in Oracle's CX ecosystem with deep Salesforce and Oracle CX integration, webinar and data-enrichment connectors and custom objects for complex routing. Each ecosystem mirrors its audience, and migrating data or intent between the two is rarely meaningful because the underlying motions differ.
Buyers frequently note that Klaviyo's tight ecommerce data integration, segmentation and pre-built flows drive measurable revenue for B2C brands, and that combining email and SMS in one tool is convenient. Recurring criticisms involve cost as profile counts and SMS volume grow, and complexity in advanced segmentation. Reviewers of Oracle Eloqua consistently credit its lead-scoring depth, orchestration and enterprise integration for complex B2B programmes, while citing a dated interface, a steep learning curve, dependence on specialists and high total cost of ownership. Sentiment rarely puts the two head to head; instead each is judged within its segment, and dissatisfaction usually appears when a team applies one to the other's revenue model.
Choose Klaviyo if you run ecommerce or B2C marketing where customers buy directly, you want email, SMS and behavioural personalisation tied to store data, and you value transparent self-serve pricing. Choose Oracle Eloqua if you run enterprise B2B demand generation with long buying cycles, need lead and account scoring integrated with Salesforce or Oracle CX, and can fund a multi-month implementation. In most cases your revenue model, not a feature comparison, decides the answer.
