Omnisend vs Klaviyo: key features comparison

Now that you’re familiar with the similarities and differences between Omnisend and Klaviyo, I’ll break down the features of each provider and compare them:

Email builder comparison

Klaviyo and Omnisend offer incredible email builders that help to streamline email marketing.

Omnisend has a drag-and-drop editor with pre-built templates. This email builder lets you get started quickly with various ready-made email designs. You can also create a template, save it, and use it repeatedly, eliminating duplicate templates. Additionally, you can customize Omnisend’s pre-built templates and make campaign-specific tweaks anytime.

Another thing that impressed me is the flexibility of Omnisend’s email builder. Even if you don’t have coding experience, you’ll have total control over how your emails look. You can use multi-column layouts and Google fonts to customize your emails. Omnisend also supports inline editing and autosave, and lets you hide specific content on certain devices.

You can even add products from your store to your emails,, along with images and pricing, without manually importing them.

Compared to Omnisend, Klaviyo provides more customization options,, but it’s less user-friendly. However, the Klaviyo email builder is not incredibly complex to use.

In fact, you can choose from 160+ ready-made email templates for marketing emails, from welcome messages to birthday offers. The best part is that they’re all customizable.

I like that Klaviyo’s customizable templates and targeted personalization allow you to create high-converting emails. Moreover, you can use dynamic coupons and A/B testing to optimize the performance of your email marketing campaigns and track the results using artificial intelligence (AI) analytics and industry benchmarks.

Klaviyo also goes a step further by letting you personalize your email templates using data from your integrated tools. This means you can show relevant products to your target audience and create the perfect email or text message.

Subscriber list

Klaviyo and Omnisend make it easy to create a subscriber list.

Since Omnisend is a multichannel platform, you may have a contact who is subscribed to one channel but unsubscribed from the other. Thanks to its easy subscriber list management and integrations, you can automatically verify the statuses of your contacts and ensure your messages are sent only to subscribed contacts.

You can also create a list of contacts that are subscribed, never subscribed, or unsubscribed from your email marketing. This will allow you to customize your messages further based on the recipients.

Klaviyo excels with its advanced filtering and tagging for more complex subscriber lists. You can create a list for your specific needs or maintain individual lists with unique consent pages. For example, you can easily create a list just for giveaways.

If your website has a signup form or a subscribe page, you can easily add all new subscribers to a list on Klaviyo. Using the list trigger, you can ensure that every new subscriber receives a series of automated emails.

For example, you can use a welcome series to send an email immediately after someone signs up for your service and then automate additional emails, each a few days apart. I love that user profiles can only enter a list-triggered flow once, reducing duplicate messages to the same recipient.

Execution-based pricing

I really like that both Omnisend and Klaviyo have execution-based pricing. This means that you can tailor the plans according to your business needs.

Omnisend offers tiered pricing with a pay-as-you-go model, which is suitable for businesses with variable needs. There are two Omnisend pricing tiers, fixed number of contacts. However, if you want to expand your contact lists, you can contact its customer support team and agree on a custom plan with a different number of contacts.

Compared to Omnisend, Klaviyo’s pricing is based on the number of subscribers you have. As a result, it can be pretty expensive if you have more extensive lists, which is why this pricing model may be better for large enterprises with more resources.

Segmentation and targeting

Omnisend supports basic segmentation based on user activity and location. You can segment your customers based on the items they’re buying, their average order value, and their purchase history.

The best part is that Omnisend offers straightforward yet robust segmentation options. You can combine multiple rules, choose from various filters, and narrow down your targeting to particular contacts who will find your messaging most relevant.

Omnisend also automatically segments customers by lifecycle stage, showing you their value and providing you with high precision. This lets you focus on high-value shoppers with personalized retention strategies, boosting repeat purchases.

Klaviyo offers advanced targeting using detailed customer data and behaviors. It simplifies audience targeting with its AI-powered segments based on predictive analytics. Simply describe your ideal customer, and Klaviyo’s AI will create the segments. Plus, Klaviyo allows you to preview segment sizes and clone audiences.

Klaviyo lets you leverage detailed, real-time data from numerous sources to create highly specific customer segments based on demographics, behavior, history, and preferences. Unlike other email marketing platforms, there are no limits on how far back you can analyze data, so you can create segments based on both historical and real-time data.

AI capabilities

Both Omnisend and Klaviyo are AI-powered email marketing tools, which makes streamlining and automating workflows easier than ever.

While Omnisend uses AI for workflow automation and send-time optimization, Klaviyo offers more advanced AI features, such as predictive analytics and automated lifecycle tracking, which allow for deeper personalization.

User experience

Beyond checking for useful features, assessing the user-friendliness of any email marketing automation tool you choose is important. So, I’ll briefly evaluate the user interfaces, navigation ease, and overall usability of Omnisend and Klaviyo.

Omnisend has a drag-and-drop editor that’s perfect for beginners. Also, its dashboard is clean and well-organized. You can easily find its eCommerce-focused features, like product carousels and personalized recommendations. Generally, you shouldn’t have any issues navigating and using this email marketing tool.

There’s also the Omnisend AI, which significantly speeds up and simplifies your email marketing process. It allows you to create customized campaigns quickly and without hassle.

Klaviyo, on the other hand, offers a broader range of marketing tools, CRM capabilities, and extensive integration options. Its AI and machine learning-powered features make it easy to use. However, due to its advanced features, it’s generally not as user-friendly as Omnisend.

Plans and pricing

Price can often be a deal breaker, especially for small businesses on a tight budget. These email marketing tools have different prices. Omnisend is more affordable, making it suitable for small to medium-sized businesses (SMBs), while Klaviyo can be expensive.

Omnisend’s plans start at $11.20 per month for the Standard deal, which comes with 500 contacts and 6,000 emails per month, unlimited web push notifications, and 1,000 published reviews (Shopify).

The Pro plan costs $41.30 per month and supports 2,500 contacts, unlimited emails, unlimited web push notifications, and unlimited published reviews (Shopify).

There’s also an entirely free version and a custom plan. I like that all of Omnisend’s plans offer the same features. The only differences are the number of contacts and emails per month and the number of published reviews.

Klaviyo has a fully customizable pricing model. This means you can choose the number of active profiles and the number of SMS or MMS messages you want to send. You can also pick an email and SMS or an email-only plan. Klaviyo’s two pricing tiers start at $20 monthly for 150-251 active profiles and 150 SMS and MMS. It also has a free plan.

The email plan offers all of Klaviyo’s features plus over 5,000 emails and 150 SMS or MMS messages. However, the email + SMS deal lacks multi-channel segmentation, multi-channel A/B testing, multi-channel attribution, and smart SMS opt-in.

Klaviyo’s free version only supports 250 active profiles, and it doesn’t come with most of the features of this email marketing automation tool, so it’s pretty limited.

I’ve put Omnisend's and Klaviyo’s plans side-by-side in the table below to enable you to compare them easily:

Omnisend	Klaviyo
Pro plan starts from $41.30 per month	Email + SMS plan starts from $20 per month
Standard plan starts from From $11.20 per month	Email plan starts from $20 per month

After carefully reviewing Omnisend and Klaviyo's functionality and pricing, it’s clear that Omnisend is more affordable. It’s much more user-friendly and offers lower monthly deals.

A final word on Omnisend vs Klaviyo

Omnisend and Klaviyo are the best email marketing tools in 2025. While both are excellent options, it’s essential to consider your business needs before choosing a marketing solution.

If you’re just starting with email marketing or want a budget-friendly solution for a small to medium-sized business, Omnisend is an excellent choice. It’s much simpler than Klaviyo, which offers advanced features and is better suited to larger enterprises.

To sum up, Omnisend is a much better pick if you’re new to email marketing, while Klaviyo requires more knowledge due to the advanced analytics and other features. But, considering its functionality and pricing, I recommend Omnisend for email marketing.
