HubSpot vs Klaviyo: Detailed Review and Comparison

Klaviyo performs better for ecommerce SMS and email marketing, while HubSpot Marketing Hub stands out for its all-in-one platform and CRM-powered marketing tools. The sections below compare both platforms across each key category and explain why each winner earned its place.

Email Marketing and Campaign Creation

Email remains one of the highest-ROI marketing channels, delivering up to $45 for every dollar spent, according to the Litmus 2025 report, which is why this choice matters.

For this category, both Klaviyo and HubSpot offer strong features, but they are built for different senders.

HubSpot Marketing Hub: A drag-and-drop builder with personalization pulled from any CRM field, plus predictive lead scoring on higher-tier paid plans (Professional and Enterprise).

HubSpot connects email marketing with its CRM platform, so you can personalize emails using details like a customer's lifecycle stage or other information stored in their profile. That level of personalization goes beyond simply adding a customer's name.

The CRM connection makes HubSpot a strong choice for B2B businesses and companies with longer sales cycles. You can automatically send emails when someone fills out a form, visits a page, or moves to a new stage in the sales pipeline.

You can also track how those emails contribute to lead generation, sales, and revenue. However, some HubSpot users say the email editor offers less design flexibility than they would like when creating highly customized branded emails.

Klaviyo: An email editor built for ecommerce. It includes product blocks, personalized product recommendations, and back-in-stock content that automatically pulls information from your online store. 

You can also add recently viewed products to an email without manually importing customer or product data.

Klaviyo also offers 160+ customizable email templates. You can create welcome emails, abandoned cart reminders, product launches, and other ecommerce campaigns without starting from scratch.

Image via Klaviyo

Many ecommerce businesses choose Klaviyo because of its strong reputation for email deliverability. But new users may need some time to learn the platform because it includes many features and settings.

Winner: Klaviyo for ecommerce email because of its product-focused features. HubSpot for B2B and CRM-driven email because of its customer lifecycle data.

Marketing Automation, Flows, and SMS

This is where HubSpot vs Klaviyo tend to differ. Klaviyo is built for ecommerce flows and native SMS, whereas HubSpot Marketing Hub is built for omnichannel sales workflows and lead nurturing. Both do marketing automation well, but they automate different journeys.

HubSpot Marketing Hub: HubSpot lets you build everything from simple automations to advanced multichannel workflows. You can automate emails, score leads, route prospects to the right sales team, trigger actions from forms, and guide leads through personalized customer journeys. 

Image via HubSpot

It also includes AI tools to help you build workflows and manage customer engagement. Marketing and sales teams also work from the same CRM data, which keeps every interaction connected. SMS is available but as an add-on.

Klaviyo: Flows purpose-built for stores, including abandoned cart, welcome, browse abandonment, post-purchase, and win-back, all triggered by live behavior.

It also includes Flows AI, which lets you describe the automation you want in plain language. Flows AI then suggests the trigger and workflow before you customize the details.

Image via Klaviyo 

SMS is native and sits in the same flows as email, so you can blend channels in one automation. For a store, that single-canvas, behavior-first design is hard to beat.

This category matters because ecommerce automation pays off. Automated flows are about 5.3% of sends but generate roughly 41% of email revenue, according to Klaviyo's 2026 benchmarks across 183,000+ customers.

Winner: Klaviyo eads for ecommerce flows and native SMS. HubSpot for B2B lead nurturing and CRM-connected workflows.

Segmentation, Data, and AI/Predictive Analytics

In this segment of HubSpot vs Klaviyo comparison, both platforms offer advanced customer segmentation and AI features, but they use them in different ways.

HubSpot Marketing Hub: Lets you create customer segments using any data stored in your CRM. You can group contacts by lifecycle stage, email activity, website visits, form submissions, or custom properties. 

Image via HubSpot

HubSpot also includes AI tools to help create content, identify high-value leads, and improve campaign performance. Higher plans include multi-touch revenue attribution and customer journey analytics, so you get a complete view of your sales and marketing funnel.

Klaviyo: Updates customer segments in real-time as shoppers browse, buy, or leave your store. With the segment builder, you can use different filters and tags to create segment profiles.

Image via Klaviyo

It uses Klaviyo AI (K:AI), its AI tool, to predict customer lifetime value, churn risk, and when a customer is likely to place their next order. 

It can also group customers by Recency, Frequency, and Monetary value to help you create more targeted campaigns. According to Klaviyo's 2026 benchmarks, AI-powered product recommendations increase average email click rates to about 3.75%.

Winner: Klaviyo for ecommerce-behavioral prediction. HubSpot for cross-funnel segmentation and attribution.

CRM, Sales, and All-in-One Platform Depth

The biggest difference between HubSpot vs Klaviyo is the CRM. This is where HubSpot Marketing Hub pulls ahead because it runs on HubSpot's CRM, so your contacts, marketing data, and reporting all live in one place. 

If customer relationship management beyond marketing matters to you, that unified foundation is the difference.

HubSpot: Its Marketing Hub is built on HubSpot's CRM, and it integrates with the Sales Hub. It stores contact data, lifecycle stages, and customer journey reports in one place. 

For a business that also runs a sales pipeline, marketing data sits in the same system the sales team already uses, so the marketing-to-sales handoff is clean. This CRM-backed approach is the core of inbound marketing at HubSpot, and it is the reason B2B teams lean toward it.

Klaviyo: It brands itself as a B2C CRM, and that is fair as far as it goes. It unifies customer profiles, adds a self-service customer hub, and offers service tools, all tuned to a consumer relationship.

What it does not have is B2B sales machinery — no deal pipeline, no quote-to-close workflow, no rep-focused lead scoring. It manages buyers and their behavior, not a sales process, and for a pure ecommerce brand, that is usually enough.

Winner: HubSpot Marketing Hub, for marketing that runs on a real CRM. Klaviyo is a focused B2C marketing and customer platform.

Ecommerce Integrations and Ecosystem

Klaviyo is ecommerce-native; HubSpot is broader but less store-deep. Both connect to Shopify, but for different reasons.

HubSpot Marketing Hub: A large ecosystem with more than 2,000 native integrations in its App Marketplace, plus a native Shopify data sync for customers, orders, and products. 

You can connect HubSpot with your CRM, CMS, webinar platform, and many other third-party tools. The Shopify integration works well, but it is only one part of HubSpot's larger ecosystem.

Klaviyo: 350+ integrations with dedicated connections to Shopify, BigCommerce, WooCommerce, Magento, and Wix. Catalog, behavior, and order data flow in cleanly to power product blocks, flows, and predictions.

Klaviyo integrations are fewer than HubSpot, but its ecommerce connections are deeper.

Winner: Klaviyo for ecommerce-store depth. HubSpot for a breadth of business-app integrations.

HubSpot vs Klaviyo: Pricing Comparison

On pricing, “cheaper” depends entirely on what you are buying. The plan tables are in the Summary Box above. Here is a breakdown of how HubSpot compares with Klaviyo in cost as you scale.

HubSpot Marketing Hub: It charges per seat and marketing contact and bundles a whole platform. As your contact count crosses a tier, the cost automatically steps up, so the bill grows with your database. Real marketing automation and reporting begin at the Professional tier, which is a meaningful jump from the Starter price.

Image via HubSpot 

Klaviyo: It charges by active email profiles and SMS credits. It is simple and cheap to start, but the cost can climb steeply at high-profile counts, especially if part of your list is not engaged.

Image via Klaviyo

An ecommerce brand that only needs email marketing for a few thousand contacts will pay Klaviyo less each month than HubSpot's Professional tier. 

But those are not the same purchase. Klaviyo's price only gets ecommerce messaging, while HubSpot's offers marketing plus a full CRM, so the fair comparison should be the value provided.

Winner: For a pure ecommerce email and SMS use case, Klaviyo has the lower-entry point and a simpler model. It is the better-value choice if you only need messaging and marketing for ecommerce brands.

HubSpot's price gets marketing features and CRM, not just email. For businesses that also need pipeline management, sales tools, and customer data in one place, the higher price can replace multiple separate subscriptions.

FAQ

Q1. Is Klaviyo better than HubSpot?

A. Klaviyo is a better choice if your business depends on ecommerce marketing and customer retention.

The best choice depends on your business goals rather than the size or popularity of the platform.

Q2. Is Klaviyo a CRM?

A. Klaviyo is a B2C, customer-data CRM built for ecommerce, with customer profiles and service tools. It is not a B2B sales CRM. It has no deal pipeline or sales-rep workflow, which is where HubSpot's CRM leads.

Q3. Can you use HubSpot and Klaviyo together?

A. Yes. Using both platforms together is a good option if one tool cannot meet all of your needs. Many growing businesses use Klaviyo to power ecommerce email and SMS campaigns while HubSpot manages customer data, sales activities, and lead nurturing. Integrating both platforms keeps customer information in sync and gives each platform a specific role.

Q4. Is HubSpot good for ecommerce?

A. HubSpot Marketing Hub works for ecommerce through its Shopify data sync and broad app marketplace, and it shines if you also want a CRM. For pure, high-volume store messaging, a store-native tool like Klaviyo usually offers deeper ecommerce flows.

Q5. Does HubSpot have SMS like Klaviyo?

A. Yes, HubSpot supports SMS marketing through add ons and integrations rather than as a core feature. Klaviyo includes native SMS marketing, allowing you to manage email and SMS campaigns together in the same automated workflows.

Q6. Is Klaviyo or HubSpot cheaper?

A. Klaviyo is generally more affordable for ecommerce businesses because it has a lower starting price for email and SMS marketing.

Q7. Which is better for a Shopify store, HubSpot or Klaviyo?

A. Klaviyo is usually the better choice for Shopify stores because it has a deep integration with Shopify and includes features built specifically for ecommerce. HubSpot is a better option if your store also needs a CRM to manage leads, customer relationships, and sales activities alongside marketing.

Q8. Which has better email deliverability?

However, inbox placement depends more on the quality of your email list, the relevance of your content, and your sending practices than on the platform itself. Following email marketing best practices will have a much greater impact on your results.

A. B2B companies are better served by HubSpot Marketing Hub. It offers the CRM-backed marketing, lead scoring, and nurturing workflows that supports longer sales cycles, none of which is Klaviyo's focus.
