HubSpot and Klaviyo are both marketing platforms, but they are solving different problems for different businesses. Klaviyo is built for e-commerce brands that want to drive revenue through email and SMS, using behavioural data from their store to personalise every send. HubSpot is built for companies that need marketing, sales, and service operating from shared data, with email as one channel in a broader inbound strategy.
The overlap is real enough to create confusion. Both send emails. Both automate campaigns. Both claim to help you grow. The distinction is in the depth of what each platform does best and what it sacrifices to get there.
Quick Overview Of HubSpot And Klaviyo
What Is HubSpot?
HubSpot is an all-in-one customer platform organised around Marketing Hub, Sales Hub, Service Hub, and Content Hub. For marketing teams, Marketing Hub handles email, landing pages, forms, SEO, social scheduling, ad management, and workflow automation, all connected to a CRM that sales and service teams also use.
The platform's strength is alignment. A lead captured through a HubSpot landing page becomes a contact in the CRM. Marketing automation nurtures that contact. When they reach a sales-qualified threshold, a sales rep picks them up with full context on every interaction. That handoff happens inside one platform without integration overhead.
What Is Klaviyo?
Klaviyo is an e-commerce-focused email and SMS platform built for brands selling on Shopify, WooCommerce, BigCommerce, or similar platforms. It pulls real-time product and behavioural data from your store and uses it to trigger automated flows: abandoned cart emails, browse abandonment sequences, post-purchase follow-ups, win-back campaigns, and product recommendation messages based on purchase history.
The platform's strength is e-commerce depth. Klaviyo knows what products a visitor viewed, what they added to their cart, what they purchased, and how much they have spent over their lifetime. That data powers segmentation and personalisation at a level that general marketing platforms do not match natively.
Klaviyo added a CDP layer in recent releases, allowing brands to unify customer data across their store, loyalty programme, and other touchpoints into a single profile. SMS is available alongside email as a native channel.
Core Difference
Klaviyo is a retention and revenue engine for e-commerce. HubSpot is a growth platform for companies that need marketing, sales, and service aligned. If your business model is direct-to-consumer and email and SMS revenue attribution is your primary metric, Klaviyo is purpose-built for that. If your business needs a CRM, inbound marketing, and multi-team alignment, HubSpot is the stronger fit.

Cost Comparison By List Size
At every list size, Klaviyo is significantly cheaper for pure email and SMS use cases. HubSpot's cost reflects the broader platform: landing pages, SEO tools, CRM, sales automation, and reporting are all included. If you need those features, the premium is justified. If you only need email and SMS, HubSpot is expensive for what you are using.
Feature-By-Feature Comparison
Email Marketing And Deliverability
Both platforms have capable email builders. HubSpot uses a drag-and-drop editor with module-based design that connects to the CMS and CRM. Klaviyo's email builder is similarly visual, with product blocks that pull live inventory data from your connected store. Inserting a product recommendation based on a customer's purchase history is a native feature in Klaviyo, not a workaround.
Deliverability is comparable on both platforms for standard send volumes. Neither has a meaningful advantage for most senders. Where Klaviyo has an edge is in send-time optimisation: it uses individual engagement data to send each contact's email at the time they are most likely to open, based on their historical behaviour.
Automation And Behavioural Flows
Klaviyo's flow builder is purpose-built for e-commerce automation. Abandoned cart, browse abandonment, post-purchase, win-back, price drop, and back-in-stock flows are all pre-built templates that connect to your store's product and order data. Setting up a five-step abandoned cart sequence takes minutes, not hours.
HubSpot's workflow builder is more flexible but less e-commerce-native. You can build complex multi-branch automation with CRM property updates, sales task creation, and internal notifications. What you cannot do natively is trigger a flow based on a customer adding a specific product category to their cart, because HubSpot does not have a native connection to product and cart data without a third-party integration.
For e-commerce automation depth, Klaviyo leads clearly. For B2B marketing automation that connects to a sales pipeline, HubSpot leads clearly.
SMS And Multi-Channel
Klaviyo's SMS is a native channel within the same platform as email. You can build flows that start with an email, follow up with an SMS if the email is not opened, and personalise both messages with the same behavioural and product data. SMS campaign management, compliance tools (opt-in collection, unsubscribe handling), and performance reporting are all built in.
HubSpot added SMS functionality at Marketing Hub Professional and above in recent releases. The capability is present but less mature than Klaviyo's, particularly for e-commerce use cases. For B2B SMS (appointment reminders, follow-up sequences), HubSpot's SMS is sufficient. For DTC brands where SMS is a primary revenue channel, Klaviyo's implementation is deeper and more e-commerce-connected.
Segmentation And Predictive Analytics
Klaviyo's segmentation is built around e-commerce signals. You can create segments based on predicted next order date, predicted customer lifetime value, churn risk score, product category affinity, total spend, and purchase frequency. These predictive properties are generated by Klaviyo's AI models using purchase history data from your store.
HubSpot's segmentation is based on contact properties, lifecycle stage, email engagement, website behaviour, and CRM activity. These are powerful for B2B inbound marketing. For e-commerce segmentation that reflects purchasing behaviour and product affinity, HubSpot requires custom properties and integrations to replicate what Klaviyo does natively.
CRM And Customer Profiles
HubSpot's CRM is the product's foundation and one of its clearest advantages. Contact records, company associations, deal pipelines, task queues, meeting logs, and full interaction timelines are built into the platform. Sales and marketing operate from the same data.
Klaviyo has customer profiles but not a CRM in the traditional sense. Profiles show email and SMS engagement, purchase history, and predictive metrics. There is no deal pipeline, no sales task management, and no handoff workflow to a sales team. For pure e-commerce brands that do not have a sales team, this is not a limitation. For hybrid businesses with both e-commerce and B2B sales, it is a gap.
Reporting And Revenue Attribution
Klaviyo's reporting is e-commerce-native. Revenue per recipient, revenue attributed to each flow, revenue by segment, and predicted revenue from upcoming campaigns are all available without custom setup. The attribution model is transparent and specifically designed to show which emails and SMS messages drove purchases.
HubSpot's reporting at Professional and above covers email performance, campaign attribution, landing page conversions, contact lifecycle, and multi-touch revenue attribution connecting marketing activity to closed deals. For B2B marketing teams that need to show pipeline impact, HubSpot's attribution is more useful. For e-commerce teams that need to show email and SMS revenue, Klaviyo's attribution is more accurate and more immediately useful.
AI Features In 2026
Klaviyo's AI covers send-time optimisation, predictive analytics (lifetime value, churn risk, next order date), subject line suggestions, and product recommendations. These are narrowly focused on e-commerce outcomes and genuinely useful for that context.
HubSpot's Breeze AI at Professional and above covers content generation, contact enrichment, lead scoring, workflow suggestions, and campaign optimisation across email, ads, and landing pages. The breadth is wider than Klaviyo's AI, reflecting the broader platform scope.
For e-commerce-specific AI, Klaviyo's predictive analytics are more actionable. For marketing AI across multiple channels and use cases including content generation and B2B lead scoring, HubSpot leads.
Integrations
Klaviyo's Shopify integration is one of the best in the e-commerce marketing category. Order data, product data, cart activity, and customer events sync in real time. WooCommerce, BigCommerce, and Magento integrations are similarly well-maintained. For brands running on these platforms, Klaviyo's integration requires minimal configuration to be operational.
HubSpot integrates with Shopify through a native connector that brings order and product data into the CRM. The integration works but is less deep than Klaviyo's native connection. For brands where Shopify data is the primary driver of marketing automation logic, Klaviyo's integration depth is a genuine advantage.

Ease Of Use And Setup
Klaviyo is faster to start for e-commerce teams. Connect your Shopify store, enable the pre-built flows (abandoned cart, welcome series, post-purchase), and you are sending revenue-generating emails within a day. The interface is intuitive for marketers who have used email tools before.
HubSpot's free CRM and Starter tier are similarly accessible. The full value at Professional tier requires more configuration and benefits from the mandatory onboarding. Teams that invest in the setup get significantly more from the platform. Teams that do not often end up using a fraction of what they are paying for.
Pros And Cons
Klaviyo
Strengths: Best-in-class e-commerce automation and flows, deep Shopify and WooCommerce integration, native SMS with e-commerce personalisation, predictive analytics for lifetime value and churn risk, revenue attribution built for e-commerce, lower cost for pure email and SMS use cases, fast time to value for DTC brands.
Weaknesses: No CRM or sales pipeline, limited utility for B2B or hybrid businesses, SMS more expensive at scale, less useful without an e-commerce data source, reporting focused on email and SMS revenue rather than broader marketing performance, smaller integration ecosystem for non-e-commerce tools.
HubSpot
Strengths: Full CRM connecting marketing and sales, strong workflow automation at Professional tier, Breeze AI across multiple marketing use cases, landing pages, SEO tools, and ad management in one platform, multi-touch attribution connecting marketing to pipeline and revenue, scales to a full customer platform.
Weaknesses: Significantly more expensive than Klaviyo for pure email use cases, e-commerce automation less native (requires integration and custom setup), mandatory onboarding fees, SMS less mature than Klaviyo for DTC use cases, meaningful cost jump from Starter to Professional.
Who Should Choose Klaviyo
Klaviyo makes sense if:
- You run a DTC or e-commerce brand on Shopify, WooCommerce, or BigCommerce
- Email and SMS revenue attribution is your primary marketing metric
- Abandoned cart, browse abandonment, and post-purchase automation are core to your retention strategy
- Your list is large enough that HubSpot's Professional tier cost is hard to justify relative to what you would use
- You do not need a CRM, sales pipeline, or marketing-sales alignment in a single platform
Who Should Choose HubSpot
HubSpot makes sense if:
- You need marketing and sales aligned on the same contact database
- Inbound marketing (SEO, landing pages, content, lead nurture) is a primary acquisition channel
- You run a B2B or hybrid business with a defined sales process
- Attribution reporting that connects email campaigns to closed deals matters to your team
- You are building on HubSpot services including CMS, CRM, and marketing automation in an integrated stack

Can You Use Both Together?
Some brands run both: Klaviyo for e-commerce email and SMS, HubSpot for B2B marketing and sales CRM. A native HubSpot-Klaviyo integration syncs contact and list data between the two platforms. This works when the use cases are genuinely distinct. When they overlap (the same contacts receiving communications from both platforms), the experience becomes inconsistent and the data difficult to reconcile.
If you are considering a dual-platform setup, define which platform owns which contact type and which channel before building the integration. Mixed ownership of the same contacts across two platforms creates attribution problems that are difficult to resolve after the fact.
Platform Comparison
FAQs
What Is The Main Difference Between HubSpot And Klaviyo?
Klaviyo is an e-commerce email and SMS platform that uses store behavioural data to drive retention and revenue. HubSpot is an all-in-one customer platform connecting marketing, sales, and service for companies focused on inbound growth. Klaviyo is better for DTC and e-commerce brands. HubSpot is better for B2B and hybrid businesses with a sales team.
Is Klaviyo Better Than HubSpot For E-commerce?
For pure e-commerce use cases, yes. Klaviyo's native Shopify integration, pre-built e-commerce flows, and revenue attribution are more e-commerce-ready than HubSpot's out of the box. HubSpot can support e-commerce marketing but requires more configuration to reach the same level of product data integration.
Which Is Cheaper: HubSpot Or Klaviyo?
Klaviyo is cheaper for pure email and SMS use cases at every contact volume. HubSpot Professional starts at $890/month plus onboarding. Klaviyo for 10,000 contacts is approximately $175/month. HubSpot's price reflects a broader platform. If you need the full platform, the cost is justified. If you only need email and SMS, Klaviyo is significantly more cost-efficient.
Does HubSpot Have SMS Marketing Like Klaviyo?
Yes, at Marketing Hub Professional and above. HubSpot's SMS is functional for B2B use cases. Klaviyo's SMS is more deeply integrated with e-commerce data, allowing personalised product-based SMS messages, store event triggers, and e-commerce-specific compliance tools that HubSpot does not yet match natively.
Which Has Better Shopify Integration?
Klaviyo. The Shopify integration syncs order data, product data, cart events, and customer behaviour in real time. Pre-built flows connect directly to store data without custom setup. HubSpot's Shopify connector is good but less deep, particularly for automation that depends on real-time product and cart data.
Who Should Choose HubSpot Over Klaviyo?
B2B companies, professional services firms, SaaS businesses, and hybrid businesses that need inbound marketing, a CRM, and sales-marketing alignment in one platform. Companies where the primary acquisition channel is content and SEO rather than paid social and direct-to-consumer.
Can You Use HubSpot And Klaviyo Together?
Yes, with a native integration that syncs contact and list data. This works for companies with genuinely separate use cases (e-commerce email in Klaviyo, B2B CRM in HubSpot). For companies where the contact bases overlap, dual-platform management creates data consistency and attribution challenges.
What Are The Pricing Models And Scaling Costs?
HubSpot prices by feature tier plus contact volume above included limits. The jump from Starter to Professional is the most significant cost increase. Klaviyo prices by active contact count. Costs scale predictably with list growth but can become expensive at very large contact volumes compared to flat-tier platforms.
