We also verified our findings using their official knowledge bases to make sure everything you read here is accurate. Here’s a brief summary of what we learned:

Don’t let the number of category wins fool you. While Klaviyo comes out on top more often, Omnisend ultimately wins this comparison. The reasons aren’t obvious at first glance, but they become clear once you look beyond individual features and consider the overall value each platform delivers.

Omnisend vs Klaviyo pricing and feature differences

We’ll begin with the biggest deciding factors – pricing and ease of use – and then take a closer look at every major feature, including email marketing, automation, SMS, AI, reporting, integrations, and more. Our goal is to answer every question you might have before choosing between Omnisend and Klaviyo. And if anything is still missing, you’ll find answers in the FAQ at the end.

Pricing plans

⭐ Omnisend: 8/10 | Klaviyo: 7/10

Disclaimer: Pricing changes frequently. All prices in this comparison were verified against Omnisend’s official pricing and Klaviyo’s official pricing as of July 14, 2026. Always confirm current costs on the official pages.

Both Omnisend and Klaviyo are quite expensive, but the cost reflects what they offer. Both platforms are built around deep eCommerce data, advanced automation, and a broad set of marketing tools designed to help online businesses grow revenue.

To make our pricing comparison as useful as possible, we included two Omnisend plans and two Klaviyo pricing options, so you can compare prices on different tiers. We also added SendPulse simply to demonstrate that not all email marketing platforms have to be expensive.

If you prefer charts to tables, here’s a visual comparison of Klaviyo, Omnisend, and SendPulse pricing across different contact list sizes and plans:

Here’s a very important detail about Klaviyo pricing. Until recently, if you wanted Klaviyo’s advanced analytics and customer data capabilities, you had to purchase its CDP (Customer Data Platform) add-on.

However, in May 2026, Klaviyo redesigned its pricing structure. You can now choose between the standard Marketing solution, which focuses on email, SMS, and marketing functionality, and two separate analytics and data add-ons – Marketing analytics and the Advanced Klaviyo data platform, which provide additional reporting, analytics, and customer data capabilities.

This new approach means companies that only need marketing tools no longer have to pay for advanced data functionality. At the same time, businesses that rely on deeper reporting and customer intelligence can purchase Marketing analytics, while those with large-scale data management needs can opt for Advanced KDP instead. The goal of the change was to make Klaviyo’s pricing more flexible and better aligned with different business needs.

Ease of use and interface

⭐ Omnisend: 8.5/10 | Klaviyo: 7/10

The scores in this category say it all, as Omnisend and Klaviyo really feel quite different in practice. Omnisend remains a focused eCommerce marketing tool, while Klaviyo is evolving into a broader customer platform. As a result, Omnisend often feels simpler and easier to navigate, whereas Klaviyo offers more depth at the cost of additional complexity.

Even though the table doesn’t show it explicitly, Omnisend is easier to understand and start using. Here’s the learning curve you can expect from both platforms:

Email builder and templates

Omnisend: 8.8/10 | ⭐ Klaviyo: 9.2/10

Email builders at Omnisend and Klaviyo are more alike than different. Both platforms provide modern builders, strong mobile responsiveness, AI assistance, and enough flexibility to create professional campaigns without much technical knowledge.

The difference is that Klaviyo pushes a bit further into optimization and personalization. While Omnisend focuses on helping eCommerce businesses create campaigns, Klaviyo invests more heavily in AI and data-driven decision-making. That’s enough to give Klaviyo a slight edge in this category, but not enough to make the overall editing experience dramatically different for most users.

Now let’s see how these builders look in practice.

Omnisend’s email builder is focused and purposeful. During testing, we liked its clean interface, which keeps most settings out of the way until you need them. The available content blocks cover all common email marketing needs, while eCommerce-specific elements such as product recommendations, product listings, discount codes, and preheaders are built directly into the editor. Overall, the experience feels streamlined and optimized for online stores rather than general-purpose marketing.

Klaviyo’s email builder feels more advanced and feature-rich from the moment you open it. The editor includes a wider selection of content blocks, reusable template systems, and AI-powered campaign creation tools designed to support larger marketing operations. During testing, we also noticed greater emphasis on brand consistency and reusable assets, making the builder particularly appealing for teams that create large volumes of campaigns.

The difference in practice is that Omnisend prioritizes simplicity and eCommerce-focused functionality, so you can easily build product-driven campaigns with minimal setup, while Klaviyo offers more flexibility, customization options, and workflow sophistication, which can be valuable for larger teams and more complex marketing strategies.

In other words, Omnisend feels easier to pick up, while Klaviyo provides a higher ceiling for marketers willing to invest more time in the platform.

SMS capabilities

Omnisend: 8.2/10 | ⭐ Klaviyo: 9.2/10

Both Omnisend and Klaviyo treat SMS as a core marketing channel, so we dedicated a separate category to comparing their SMS features. Here’s everything you need to know before choosing between them.

Our takeaway is that Omnisend’s SMS capabilities are more than enough for most eCommerce businesses that want to combine email, SMS, and push notifications in the same marketing workflows. Klaviyo earns the higher score because it extends SMS beyond marketing, adding conversational messaging, richer automation, stronger compliance tools, and AI-powered customer interactions.

Marketing automation

Omnisend: 9.2/10 | ⭐ Klaviyo: 9.4/10

This is not a case where one platform offers automation features, and the other doesn’t, as both Omnisend and Klaviyo are genuinely strong. Klaviyo wins because it gives you more room to grow. As your customer data becomes richer and your marketing becomes more sophisticated, Klaviyo offers more opportunities to personalize journeys and fine-tune how customers move through them.

Have a look at how automation builders work in practice.

Omnisend’s automation builder is clean and approachable. During testing, we liked how easy it was to follow the logic of a workflow thanks to its linear structure and clearly visible triggers, filters, and exit conditions. The builder also includes practical eCommerce features such as behavioral splits, A/B testing, and automatic workflow exits when a customer completes a purchase.

Klaviyo’s automation builder is more advanced and data-centric. The freeform canvas is designed for larger customer journeys, making complex branching easier to visualize and manage. During testing, we also noticed a stronger emphasis on customer data, audience segmentation, timing controls, and operational actions that go beyond sending marketing messages.

The biggest difference between these builders is how they personalize customer journeys. Omnisend tends to react to subscriber behavior after contacts enter a workflow, making it easy to build effective automations without extensive customer data. Klaviyo uses existing customer information to personalize journeys from the very first step. As a result, Omnisend feels simpler and more approachable, while Klaviyo offers greater flexibility and is better suited for businesses managing more complex customer journeys at scale.

Contact management

Omnisend: 9.2/10 | ⭐ Klaviyo: 9.5/10

The better you understand and organize your audience, the more relevant your email marketing becomes. Both Omnisend and Klaviyo provide excellent segmentation and contact management capabilities. Here’s what they offer:

Both platforms provide powerful segmentation tools that will satisfy the needs of most eCommerce businesses. Klaviyo earns the higher score because it builds more of its marketing around customer data and predictive insights, making segmentation an integral part of the platform rather than just a way to organize contacts. As businesses grow and customer behavior becomes more complex, that deeper data model offers greater flexibility.

Signup forms and landing pages

Omnisend: 8.6/10 | ⭐ Klaviyo: 8.8/10

This is one of the closest comparisons in the article. Both platforms provide powerful signup form builders, and neither leaves you missing any essential functionality. Klaviyo pulls ahead by offering more tools for optimizing conversions, while Omnisend focuses on making advanced lead capture easy to build and manage. For most businesses, the difference won’t be dramatic and will come down to whether you value additional optimization options or a simpler workflow.

Omnisend’s form builder focuses on helping businesses capture leads with minimal effort. During testing, we particularly liked its audience targeting and flexible multi-step forms. Features such as separate Success and Subscribed states, automatic redirects, and built-in gamification make it well-suited for eCommerce stores that want practical lead generation without unnecessary complexity.

Klaviyo’s form builder places more emphasis on conversion optimization. We liked the simultaneous desktop and mobile preview, purpose-built multi-step architecture, and content blocks designed to increase conversions, such as reviews and coupon elements. The builder feels like it’s designed for marketers who regularly test and optimize signup experiences.

Both builders are excellent in their own way. Omnisend focuses on showing forms to the right people and managing subscribers once they convert, while Klaviyo focuses on increasing the likelihood that visitors convert in the first place. That’s why Klaviyo earns a slight edge – it provides more tools for optimizing the signup journey itself, whereas Omnisend prioritizes simplicity, targeting, and eCommerce practicality.

Integrations

Omnisend: 8.2/10 | ⭐ Klaviyo: 8.7/10

Integrations are useful, but they also add complexity. Choosing a platform that includes features like CRM and multi-channel marketing out of the box, such as SendPulse, means fewer tools to manage and fewer things that can go wrong. Here’s what Omnisend and Klaviyo offer in terms of integrations:

As an eCommerce business, chances are you’re most interested in Shopify integration. Are Omnisend and Klaviyo equally good at it? Both platforms connect to Shopify quickly and without coding, automatically syncing customers, products, and orders. For most eCommerce businesses, that’s all they’ll ever need.

The difference becomes apparent when you start building more sophisticated marketing campaigns. Klaviyo imports a wider range of Shopify events and customer data, giving you more opportunities to create advanced segments, automations, and reports. Omnisend still offers a strong Shopify integration, but some data syncs less frequently and a few limitations make it slightly less flexible for businesses that rely heavily on Shopify data.

AI features

Omnisend: 7.2/10 | ⭐ Klaviyo: 8.7/10

We’ve been discussing AI features throughout this comparison, but here we’ve gathered them in one place so you can clearly see which platform does more to automate and optimize your marketing.

Omnisend uses AI primarily as a productivity tool, making it easier to create emails and build segments. Klaviyo goes further by using AI to generate campaigns, automate workflows, predict customer behavior, and optimize marketing decisions. The result is a more comprehensive AI toolkit for data-driven eCommerce businesses.

Deliverability

⭐ Omnisend: 10/10 | ⭐ Klaviyo: 10/10

Inbox placement is one of the most important aspects of email marketing, and fortunately, both Omnisend and Klaviyo perform very well in this category.

We believe that choosing the right platform is important, but your own email marketing practices have a much bigger impact on deliverability. Most modern bulk email sending services already include the technical features needed to reach the inbox. Here’s what our expert says:

Almost 80% of deliverability depends on the marketer's practices, namely list hygiene, permission-based sending, consistent sending pattern, and content relevance. Only about 20% depends on the ESP, which handles infrastructure, authentication, and IP reputation management.

Both platforms are strong winners in the deliverability, as they follow email deliverability best practices and provide the tools businesses need to maintain a healthy sender reputation.

Reporting and analytics

Omnisend: 8.2/10 | ⭐ Klaviyo: 10/10

Advanced automation is only valuable if you can understand the results. Fortunately, both Omnisend and Klaviyo back their automation capabilities with equally strong reporting and analytics.

The biggest difference here is not the amount of data as both platforms already provide more than enough reporting for most eCommerce businesses, but flexibility.

Omnisend does an excellent job of presenting eCommerce metrics in ready-to-use dashboards, making it easy to understand what’s happening without much setup. Klaviyo, on the other hand, gives you much more control over how that data is analyzed, filtered, and presented. With its updated pricing, you can now choose how much reporting and analytics you need instead of paying for the full set of advanced data tools from the start.

All this makes Klaviyo a stronger choice for businesses that regularly build custom reports or analyze performance from multiple angles.

Customer support

⭐ Omnisend: 8.4/10 | Klaviyo: 7.3/10

Getting started with a new platform isn’t always straightforward. Since both Omnisend and Klaviyo are premium-priced solutions, quality onboarding and responsive customer support are especially important. Here’s what each platform offers:

Both platforms invest heavily in documentation and onboarding, but Omnisend puts greater emphasis on direct customer assistance. Faster access to human support, combined with consistently higher user ratings on Capterra, gives it a clear advantage in this category.

Your decision checklist

Although the two platforms are quite similar, there are still some important differences. We’ve gathered them all in one place to help you decide which one best fits your needs.

If three or more of your answers point to the same platform, that’s likely the one you should choose. Just remember that changing email marketing platforms isn’t free – it takes time, effort, and often additional costs. Think beyond your current needs and choose a platform that will continue to support your business as it grows.

Final verdict and recommendations

⚖️ Final scores: Omnisend – 8.7/10 | Klaviyo – 8.6/10

Even with its renewed pricing structure and solutions, Klaviyo remains one of the most expensive email marketing platforms on the market. That is ultimately what costs it in this comparison, although only by the narrowest possible margin of just 0.1 points.

Beyond pricing, it’s hard to criticize either platform. Klaviyo is an outstanding choice for eCommerce businesses, especially larger ones that can take full advantage of its advanced analytics, AI, and customer data capabilities. Omnisend is equally impressive for eCommerce and offers a more accessible balance between features, usability, and price.

Would we recommend them? Absolutely, but only if you’re running an eCommerce business. If you aren’t selling products online, you’ll likely pay for many features you simply won’t use.

If your focus is newsletters, informational emails, non-profits, or smaller businesses, an all-in-one platform will usually be a better fit. Here are a few alternatives worth considering:

• SendPulse if you need email marketing together with chatbots, CRM system, automation, and other marketing tools in one platform.
• Kit (formerly ConvertKit) if you’re a creator looking for a generous free plan and a platform focused primarily on newsletters and audience building.
• ActiveCampaign if advanced automation is your top priority, but Klaviyo or Omnisend are outside your budget.
