Email Builder 

Let’s start with the most important feature and see how you can build an email campaign in Klaviyo vs Omnisend.

Klaviyo Email Building 

This platform makes it relatively easy to build email campaigns thanks to its simple email builder. You can upload your templates or use one of the good-looking Klaviyo templates. To start customizing them, you will rely on drag-and-drop functionality. However, compared to other platforms the customization options are rather limited. Some of the personalization possibilities include adding text, images, columns, tables, or buttons. 

A feature you’ll find useful if you work in eCommerce is the fact that you can easily add products from your store into your email’s body.

Klaviyo Email Building 

Omnisend Email Building 

Creating email campaigns also comes easy with this platform as it features a visual builder that allows you to drag and drop different elements. Although Omnisend provides fewer email templates than Klaviyo, this platform is more flexible in terms of email customization. You can easily add video content to your campaigns or use HTML coding to further personalize your emails. 

This software also integrates quite well with eCommerce platforms, which enables you to add products to your email campaigns by using the Product Picker. You can create smart product recommendations with Omnisend if you also use Nostro. Other features that are useful for online stores include gift boxes, scratch cards, or unique discount codes.

The verdict 

Omnisend wins in this first round for its flexibility. 

List Building 

Each one of these tools offers specific features that allow you to draw leads and manage them with ease. 

Klaviyo List Building 

You can start building a list organically with Klaviyo by using the contact details you get from the people that visit your website. To be able to do this, the platform allows you to create different types of sign-up forms and embed them into your site. To increase the likelihood of conversion, you can customize the pop-up forms by using specific fields. 

Also, the platform offers a Triggered Forms feature that enables you to automatically show the forms in key moments, for example, by featuring a discount when the visitor is getting ready to leave the website or trigger sign-up forms when the visitor accesses a specific section or clicks on a link.

Omnisend List Building 

Omnisend offers forms as well, but they are less elaborate compared to Klaviyo. You don’t get triggered forms with this platform, but you can access another useful feature that’s not present in Klaviyo - Wheel of Fortune forms. These are pop-up forms that feature discounts. The advantage of these interactive forms is that they’re quite effective in drawing visitors’ attention.

Another lead generation strategy the platform focuses on is landing pages. By crafting attractive landing pages with this tool, you can promote several business-related aspects such as a new product or invite visitors to join an event.

Omnisend List Building 

The verdict

Both platforms have their pros in this category. We consider it a tie


Segmentation is an extremely important feature for email marketing platforms as it allows you to divide your audience based on specific criteria such as interest or demographics in order to target each group with personalized messages. 

Klaviyo Segmentation 

Klaviyo allows you to segment your list by building an unlimited number of segments based on very specific criteria. There is no limit to the number of criteria you can use for each segment. The platform’s form builder allows you to gather leads and start segmenting your list automatically. Virtually, Klaviyo allows you to segment your audience according to any criteria that might interest you. Some of the main segmentation criteria you can rely on include purchase history, location, previous interaction, etc. 

This tool’s complexity makes it a bit harder to get used to, but it also allows you to create well-targeted data-driven campaigns. Moreover, you can also synchronize your segments with your Facebook audience to implement the right ads strategy. Since this platform also provides SMS messaging, the segments can integrate with this feature to enable you to send customized messages.

Omnisend Segmentation 

Omnisend also allows you to build different audience segments based on specific criteria. Their segmentation process is limited because you can build some segments based on the pricing plan you purchase. This platform allows you to divide your contacts into three main groups: purchase behavior (based on the pages your contacts visit, the products they add to the cart, their recent purchases, etc.), profile data (the segmentation criteria are contacted’ personal info and demographics), and campaign activity (how your contacts interact with your emails). 

The segmentation process is logical and easy to carry out, and the 3 main groups are extremely useful for eCommerce companies. You can also synchronize your segments with Google for ad retargeting purposes.

The verdict

Both tools offer similar options. However, Klaviyo offers tons of options, so we consider it the winner.

A/B Testing

Tests are essential steps you need to take if you want to make sure your emails end up in your contacts’ inboxes or understand what type of content they appreciate the most.

Omnisend Testing

Omnisend is not devoid of testing capabilities. However, this platform’s testing features are far less limited than what you get from Klaviyo. You can only test sender names and your emails’ subject lines

The verdict

Klaviyo is the definite winner as it offers the possibility to A/B test with more elements. 


Automation is key to a successful email marketing strategy. Automated email sequences not only help you save time but also keep your leads constantly engaged. 


Klaviyo features powerful automation that is also easy to set up and launch. Although other platforms that typically cost more than Klaviyo offer more advanced automation, Klaviyo’s workflows are more than enough especially for small businesses or newbies. You can create multi-branched customer journeys based on your contacts' actions and choose one of the numerous ready-made flows to speed up the process, such as abandoned cart automated workflows. 

The automation builder is based on a visual approach, and you can choose to add triggered or conditional splits to your flows. Moreover, you can implement automation across multiple channels. As an extra, Klaviyo also offers iOS app push notifications.

Omnisend’s automation features are still relatively new. This platform also features triggered splits and conditionals split.

This multi-channel approach will also help you understand what type of interaction is more engaging for your contacts. Moreover, Omnisend provides browser push notifications, and it also offers ready-made recipes such as abandoned cart workflows.

Both tools offer similar automation capabilities. We consider both winners. 


Integrations allow you to connect different third-party apps to your platform to facilitate data sharing and manage your marketing strategy across multiple channels.

Other popular platforms that connect with this software include Drupal, PresaShop, LoialtyLion, Big Cartel, Smile, Volusion, ReCharg. Omnisend offers more than 30 native integrations.

Klaviyo cto be more advanced from an integration point of view. However, if you need an email marketing platform for eCommerce integrations, both options are great. 

Ease of Use 

Even if you are an experienced marketer, you probably don’t want to waste hours in a row trying to figure out how to use your email marketing platform. Luckily, both platforms we’re focusing on in this comparison are pretty easy to use. 

Klaviyo Ease of Use 

Klaviyo offers a very intuitive and well-organized interface where choosing the functions is not difficult. This platform allows you to segment your audience pretty fast, and the rich personalization features allow you to access customers’ purchase history, viewing history, and other details. The automation is also quite easy to set up and track.

One of the main features that make this platform easy to use is its ability to integrate with tons of third-party apps.  The open API contributes to creating even more integrations than what you can already find on Klaviyo’s list.

Omnisend Ease of Use 

Omnisend is by far one of the most intuitive platforms targeted toward eCommerce small businesses. The interface is clean and very well organized. The email automation builder is easy to use, and the workflows are logical. Given the automation builder’s drag-and-drop functionality and visual approach, creating automation can take as little as several minutes. Thanks to Omnisend’s product picker it is easy to add products to your email campaigns.

The verdict 

Both Klaviyo and Omnisend are easy to use. It’s a tie once again. 


Let’s take a quick look at Klaviyo vs Omnisend from a pricing perspective to figure out which platform offers the best value for money. 

Klaviyo Pricing 

This software’s price depends on the number of contacts you have. You can use it for free but only if your list has a maximum of 250 contacts. The number of SMS messages you send each month will also influence the subscription price. Each message costs $0.10 and each MMS brings an additional cost of $0.03. For a list of 251-500 contacts, the price is $20 per month. You pay more than double for a list of 1,001 - 1,500 contacts and $70 per month for a maximum of 3,000 contacts.

The standard plan also allows you to send 15,000 emails per month but also offers SMS marketing and automation. The next tier is the Pro plan, which costs $99 per month and also includes omnichannel marketing. Each plan’s price grows if you exceed 500 contacts. 

Omnisend Pricing 

The verdict 

Omnisend is the cheaper option. 


Reports are another must-have feature a robust email marketing platform should offer. Without thorough reporting, you wouldn’t be able to track your results and improve your campaigns. 

Klaviyo Reporting

This software offers excellent reporting capabilities. You can easily keep track of your email campaigns’ performance but also monitor other key business aspects. You can customize the platform’s reporting dashboard to generate the analytics that best suits you and get all the information you need at a glance

You can track your campaign metrics, what is going on with a specific segment of your audience, marketing-attribution growth, revenue metrics, website visits, customers’ behavior (e.g. purchase data, preferences, etc.), and plenty more. Another great plus is the platform’s predictive analytics feature that helps you estimate your customers’ behavior.

Klaviyo Reporting

Omnisend Reporting

Omnisend also offers great reporting options. However, their advanced features are only available for customers who have a higher subscription plan. Another limitation is that you can only get analytics for the events that took place during the past 18 months. Some of the analytics you can generate with this platform include open rates, click-through rates, and different client demographics. 

A useful feature is the conversion rate report that shows you which type of message is the most effective. Omnisend’s reporting tools are connected to what is happening on your website or with your campaigns, you always get real-time data.
