Klaviyo vs HubSpot: Honest Pricing and Feature Review [2026]

Both Klaviyo and HubSpot have a reputation for being expensive and difficult to learn, and judging by user reviews, that’s largely true. But after testing them ourselves, we found that those drawbacks aren’t really comparable.

Klaviyo vs HubSpot pricing and feature differences

We begin with the factors that matter most when choosing an email marketing platform: pricing first, then the core features, and finally the areas that may influence your decision but are less likely to determine it. We’ll start by comparing pricing across different plans and then look at whether each platform is actually worth the money.

Pricing plans

⭐ Klaviyo: 7/10 | HubSpot: 4/10

Disclaimer: Pricing changes frequently. All prices in this comparison were verified against Klaviyo’s official pricing and HubSpot’s official pricing as of September 1, 2026. Always confirm current costs on the official pages.

Just to be clear, we’ve awarded a perfect 10/10 for pricing to several email marketing platforms we’ve tested. Klaviyo and HubSpot simply aren’t among them. Both are expensive compared to most competitors, and HubSpot becomes particularly costly once you start adding its different Hubs and advanced features.

Below, we’ve compared pricing across multiple plans because many of the features that make these platforms stand out are only available on higher-tier plans. We’ve also included SendPulse’s Standard plan to show that you don’t have to spend this much to get a powerful email marketing platform.

We also turned these numbers into a chart, in case you find it easier to compare prices visually.

If both Klaviyo and HubSpot are beyond your budget, you can stop here. But we have to warn you – they really do offer unique features for the price they charge. Keep reading, because they might even offer capabilities you didn’t know you needed.

Ease of use and interface

⭐ Klaviyo: 7.5/10 | HubSpot: 7/10

As mentioned earlier, neither platform is particularly simple or intuitive. Both Klaviyo and HubSpot are large platforms with many features that aren’t always easy to navigate. Here’s what you can expect during your first days of using them.

The biggest takeaway from our testing is that both platforms assume you’ll invest time learning them, and both reward that investment. The difference is that Klaviyo specializes in eCommerce, while HubSpot spreads its complexity across marketing, CRM, sales, and customer service.

Here’s how your learning curve might look:

Email builder and templates

⭐ Klaviyo: 9.2/10 | HubSpot: 8.4/10

If we looked only at the email builder, Klaviyo would be the clear winner. It gives you more creative freedom, stronger eCommerce personalization, and more tools to optimize campaigns that generate revenue. HubSpot gives up some of that flexibility in exchange for a builder that works hand in hand with its CRM.

Now it’s time to see how both platforms perform in real use.

Klaviyo has one of the most advanced email builders we tested, especially for eCommerce. Beyond the usual drag-and-drop editing, it gives you unusually detailed control over layout with separate text area, block padding, and dedicated display settings for individual elements. Personalization goes beyond merge tags; the Insert menu supports dynamic content, conditional blocks, and product-driven content.

Combined with blocks like coupons, review quotes, and product recommendations, the builder is clearly designed for brands whose emails revolve around catalogs, purchase history, and customer behavior.

HubSpot puts CRM data at the center of the email editing experience. Instead of showing placeholders, the builder renders personalization with real contact information directly in the preview, so you immediately see what a recipient will get. It also includes CRM-specific tools, like sender personalization and suppression management.

While the design controls aren’t as deep as Klaviyo’s, the builder is tightly connected to the rest of HubSpot, making it easy to create emails that fit naturally into larger marketing, sales, and customer success workflows.

Our takeaway? Klaviyo is built around products, customer behavior, and dynamic eCommerce content, so most of its advanced features help you personalize emails using shopping data. HubSpot assumes every email is part of an ongoing customer relationship, so it focuses on CRM data, real contact previews, sender personalization, and tools that support sales and customer communication.

SMS capabilities

⭐ Klaviyo: 9.2/10 | HubSpot: 7.4/10

In case SMS marketing is a priority for your business, we’ve taken a close look at how both Klaviyo and HubSpot handle it. Here’s what you can expect from each platform and which types of businesses they’re best suited for.

The gap between these platforms is larger than the scores suggest. Klaviyo has clearly invested in making SMS a first-class marketing channel, with conversational automations, international support, and features built specifically for eCommerce.

HubSpot’s SMS capabilities fit naturally into its CRM ecosystem, but they don’t have the same depth. Businesses that rely on SMS for customer acquisition and retention will get far more value from Klaviyo, while HubSpot is better suited to teams that just want to add SMS to an existing CRM-driven marketing strategy.

Marketing automation

⭐ Klaviyo: 9.4/10 | HubSpot: 9.3/10

The scores for marketing automation are almost identical because both platforms excel at what they were built to do. Klaviyo creates sophisticated customer journeys that drive eCommerce revenue, while HubSpot focuses on automating the entire customer lifecycle, from lead generation to sales and beyond.

Klaviyo’s automation builder is one of the cleanest we’ve tested. Despite supporting complex customer journeys, the interface stays minimal, with just a handful of actions covering messaging, data updates, delays, and branching. The freeform canvas makes multi-branch automations easy to follow, while inline controls let you change email status, insert new steps, or review timing without opening individual nodes.

The standout feature, however, is Audit flow. Instead of simply flagging configuration errors, Klaviyo’s AI reviews the entire automation and suggests improvements to timing, structure, and logic. It’s the first platform in our comparison series to offer an AI assistant for the workflow as a whole rather than individual automation steps. Combined with native support for email, SMS, and WhatsApp, the builder feels purpose-built for eCommerce teams managing sophisticated customer journeys.

HubSpot approaches automation from a CRM perspective. Workflows aren’t just sequences of emails; they’re connected to customer records, lifecycle stages, business goals, and sales processes. You can trigger automations when contacts reach a specific CRM stage, send emails to associated contacts instead of the enrolled record, manually enroll contacts into existing workflows, and measure whether contacts achieve the workflow’s goal.

The builder also includes several operational tools that become valuable as automations grow more complex. Keyboard shortcuts, workflow cleanup, performance history, and built-in goal tracking make it professional business software.

These builders are optimized for different kinds of work. If your automations revolve around customers, products, and purchases, Klaviyo is the stronger choice. If they focus on leads, sales pipelines, and customer relationships, HubSpot is a better option.

Contact management

⭐ Klaviyo: 9.5/10 | ⭐ HubSpot: 9.5/10

When it comes to contact management, Klaviyo focuses on customer behavior, purchases, and predictive insights, making segmentation a powerful tool for driving eCommerce revenue. HubSpot expands segmentation beyond contacts to the entire CRM system, making it much better suited to businesses where marketing, sales, and customer management all rely on the same data.

One thing that often surprises new HubSpot users is the lack of contact tags. Unlike most email marketing platforms, HubSpot deliberately doesn’t support freeform tags for contacts. Instead, it encourages businesses to organize data using custom properties, lists, segments, and lifecycle stages.

According to HubSpot, this leads to cleaner, more structured customer data because information like industry, source, or customer type is stored in dedicated fields instead of being mixed together as tags. It’s a CRM-first approach that works well once your data model is in place, but it can feel restrictive for teams used to quickly tagging contacts on the fly.

Klaviyo approaches customer data from the opposite side. Instead of a CRM-first model, it’s built on a native customer data platform (CDP): the Klaviyo Data Platform unifies web, email, SMS, and purchase data into one real-time customer profile, which is what powers its predictive segmentation (lifetime value, churn risk, and predicted next order). HubSpot reaches similar depth from the other direction, unifying that same data through its Smart CRM. That’s why the two tie here: Klaviyo leads on out-of-the-box B2C customer data, while HubSpot leads on unifying it across the business.

CRM

Klaviyo: 8/10 | ⭐ HubSpot: 9.8/10

We couldn’t leave CRM out of this comparison, since it’s a crucial part of HubSpot. What’s more, Klaviyo now also has enough CRM capabilities to make the comparison meaningful. While HubSpot still offers one of the most comprehensive CRMs on the market, Klaviyo has become a legitimate alternative for some businesses.

HubSpot’s CRM is much more than a customer database, as it connects contacts, companies, deals, tickets, and custom objects into a single system, giving marketing, sales, and support teams a shared view of every customer relationship. That’s why it can handle pipelines, deal management, forecasting, account ownership, and cross-team reporting. Klaviyo’s CRM is excellent for managing customer profiles and eCommerce interactions, but HubSpot is built to manage the entire customer lifecycle across multiple business teams.

Signup forms and landing pages

⭐ Klaviyo: 8.8/10 | HubSpot: 8.5/10

Both Klaviyo and HubSpot offer excellent forms. Klaviyo puts more effort into helping you increase signup rates, while HubSpot is more focused on improving the quality of the leads you collect. If growing your audience is the priority, Klaviyo has the edge, but if every submission feeds a sales process, HubSpot’s approach will pay off more.

Let’s see how their form builders compare.

Klaviyo’s builder is designed for conversion-focused eCommerce campaigns. It offers a visual editing experience with simultaneous desktop and mobile previews. Design customization is also one of its strengths, with flexible typography, individual padding controls, and block-level visibility settings that let you show or hide elements for desktop or mobile independently.

The platform also includes features rarely found in form builders, such as a native spin-to-win pop-up and multi-step forms with customizable intermediate steps. Rather than simply collecting email addresses, Klaviyo encourages merchants to build engaging signup experiences that maximize conversions and fit naturally into online stores.

HubSpot is more data-oriented and, instead of emphasizing visual customization, it focuses on collecting better information. Every field is connected to CRM properties, so it’s easy to map submissions directly into customer records, while field-level logic allows you to tailor forms based on user responses.

One of HubSpot’s standout features is AI form shortening, which automatically hides fields the platform already knows about a visitor. Combined with progressive profiling, connected CRM properties, email domain blocking, and advanced field options, the builder is clearly designed to improve data quality rather than make forms more visually engaging.

These builders reflect the priorities of their platforms. Klaviyo treats forms as a conversion tool, while for HubSpot, they are an extension of the CRM system. Choose Klaviyo if your goal is growing an email list through promotional pop-ups, and opt for HubSpot if forms are your way to qualify leads and enrich CRM data.

AI features

⭐ Klaviyo: 9.2/10 | ⭐ HubSpot: 9.2/10

We’ve gathered AI features in one place in case AI is one of the main factors influencing your choice of an email marketing platform.

Both platforms have moved well beyond using AI just to write emails. Klaviyo uses it to help you build campaigns and optimize automations, while HubSpot extends AI across the entire customer journey, from marketing and segmentation to CRM and sales. If email marketing is your main focus, both platforms offer excellent AI capabilities. The advantage shifts toward HubSpot only if you plan to use AI across your wider business operations.

Integrations

Klaviyo: 8.7/10 | ⭐ HubSpot: 9.2/10

HubSpot is clearly stronger in integrations. Beyond its much larger app marketplace, it exchanges data far more deeply with the tools it connects to. Klaviyo still has a strong integration library for eCommerce and marketing, but it gets more limited once you need to connect multiple stores, CRM data, or a broader range of business objects.

Since Klaviyo is known as a top eCommerce email platform, we looked at how its Shopify integration compares with HubSpot’s. Both sync Shopify data in real time, but they use it differently: Klaviyo turns orders, abandoned checkouts, and product views into marketing events for segments and automations, while HubSpot writes that data to contact records and can auto-create deals from purchases.

So even though HubSpot wins on integrations overall, Klaviyo is the stronger fit for eCommerce brands focused on retention through email and SMS.

Deliverability

⭐ Klaviyo: 10/10 | ⭐ HubSpot: 10/10

Klaviyo and HubSpot both give most businesses everything they need for excellent deliverability, which is why they tie here. They just get there a little differently: Klaviyo leans toward proactive monitoring and list hygiene, while HubSpot offers more sending infrastructure, like dedicated IPs with automated warm-up.

Want to maximize your inbox placement? Here are some recommendations from SendPulse’s deliverability experts:

1. Segment by email engagement, not product activity.
2. Send large campaigns to engaged subscribers first, then inactive ones gradually.
3. Make re-engagement campaigns opt-in to stay, not opt-out.
4. Keep sending volumes consistent and predictable.
5. Treat list hygiene as your primary defense against spam traps, not just email authentication.

Those are the things that have the biggest impact on long-term deliverability.

Reporting and analytics

Klaviyo: 9/10 | ⭐ HubSpot: 9.2/10

Good reporting helps you understand what works, optimize future campaigns, and make better marketing decisions. Fortunately, reporting is another area where both platforms perform exceptionally well.

Klaviyo helps you understand what drives eCommerce revenue. HubSpot looks beyond marketing, connecting reports with CRM data, sales activity, customer journeys, and revenue attribution. If your reports are mainly used by the marketing team, Klaviyo offers a more focused experience, while HubSpot provides a much broader view of the business.

Customer support

Klaviyo: 7.3/10 | ⭐ HubSpot: 7.4/10

When you start using a new platform, you’ll probably need some assistance from time to time. In many cases, an AI assistant will be enough, but sometimes you’ll need help from a real person. Here’s everything Klaviyo and HubSpot offer to make onboarding and everyday use as easy and pain-free as possible.

Neither platform stands out in this category. Klaviyo puts more emphasis on helping users learn independently through frequent live training sessions and self-service resources, while HubSpot invests more in structured onboarding and hands-on assistance, especially for larger companies that use the platform across multiple teams.

Real users’ reviews on Klaviyo and HubSpot

One theme comes up again and again in reviews of both platforms: pricing. Even users who are otherwise very happy with the product often mention that costs grew much faster than they expected as their business expanded. Here are some examples for Klaviyo:

Users say the same about HubSpot Marketing Hub:

Beyond that, however, the feedback starts to diverge in a way that closely matches what we found during our own testing. Klaviyo users are generally willing to pay the premium because of its deep eCommerce capabilities, particularly its segmentation, Shopify integration, and automation.

HubSpot users, meanwhile, justify the higher cost because they’re getting much more than an email marketing platform — they’re investing in an all-in-one system that runs more of their business.

The only thing worth keeping in mind is that HubSpot has a much larger customer base, which naturally brings a wider range of experiences, including some serious complaints. That doesn’t automatically make it any better or worse than Klaviyo’s, but it’s a reason to read the reviews themselves rather than judge either platform on its star average alone.

If three or more of your answers point to the same platform, that’s probably the right choice for your business.

Final verdict and recommendations

⚖️ Final scores: Klaviyo – 8.6/10 | HubSpot – 7.9/10

Would we recommend Klaviyo? Absolutely, but only if you’re running an eCommerce business and want to maximize revenue with data-driven email marketing.

Would we recommend HubSpot? Yes, but only if you plan to take advantage of its broader ecosystem of Hubs and business tools. If you’re only looking for an email marketing platform, it’s simply too expensive.

What if neither platform fully corresponds to your needs? Here are a few alternatives that might be a better fit:

• Choose SendPulse if you want an AI-driven marketing platform with a built-in CRM system at a much lower cost than HubSpot.
• Consider Omnisend if you’re an eCommerce business, but Klaviyo is beyond your budget.
• Take a look at ActiveCampaign if automation is your top priority and you want to build your email marketing around customer data.

Overall, choose your vendor as you would a strategic partner, looking not only at your needs today but also anticipating what you’ll need tomorrow.
