Choosing the right marketing tool can help your store grow faster than usual. Many business owners and marketers end up comparing Omnisend and Klaviyo since these platforms lead the market. Both tools are capable of sending emails and building customer behavior-based workflows to help you sell more.
A common misconception is that more expensive tools are usually better and more reliable, but after meticulous research, we’re here to prove it wrong. More technical tools are not necessarily reserved for larger corporations, and more intuitive tools aren’t made for small businesses alone. Regardless of your size, you can have a tool that’s powerful without being clunky.
Omnisend works well for roughly 95% of ecommerce brands because it’s reliable, powerful, and flexible enough to efficiently serve both small shops and large international enterprises alike. It provides a wide range of features and solutions that allow you to reach your goals without overspending or needing to hire a team of dedicated data specialists.
Klaviyo offers significantly more depth than Omnisend, but it’s usually reserved for brands that actually need to look at every single bit of data. It does, however, take hours of learning and setup, even with extensive experience and knowledge in the field. If you require niche segmentation and highly specific automation setups, then it’s worth the price.
That’s a brief general overview, but now, let’s go deeper and analyze the two platforms’ features side by side.
Essential automation workflows
Automations are imperative to your ecommerce business as they automatically send emails to your subscribers based on the different actions they take. You can set up an automation to send welcome emails to someone who just signed up, abandoned cart emails to someone who added items to their cart but then left abruptly, post-purchase follow-ups, and much more.
Omnisend provides a huge library of pre-built workflow templates that you can use to generate either the full workflow, or a base layer upon which you can build a more advanced automation. All of the general workflows are already prepared for you to use, so you don’t have to do anything manually, except customize if needed. You can even combine email, SMS, and push notifications into a single workflow if that’s what you need.
Klaviyo has very strong automation features for ecommerce stores. You can build complex paths that change based on many different rules. It allows for a lot of control over what each subscriber sees, but setting these up also takes more time and expertise than it does in other tools. Complex automations come at a steep learning curve, and you’ll need to invest time to learn how it works. You may have to hire an expert, or an entire team, to handle and experiment with the customer journey, so you must take into account whether that’s what you really need.
You can, of course, skip these advanced capabilities and just focus on standard workflows, but you’ll still be paying the price for the depth that you’re not using. You might as well use a more affordable and intuitive tool if standard-to-advanced functionality is all you need.
Adding products
Selling your products is likely the main reason why you’re looking for an ESP in the first place, so it’s important to see which one provides a more convenient experience doing that.
Omnisend allows you to add products to your email campaign directly from the email builder. Once you select the product picker block, a sidebar appears with a search bar connected to your online store. You enter the name of the product you want to add, and it pops up in the list. Then, you click on it to add the product to the email, and it appears in your builder with the name, image, description, price, and purchase link.

If you don’t want to add products manually, you can use the dynamic product recommender block where you have three choices: best-sellers, most viewed products, or recently added items. Once your campaign goes live, the recipients will see the chosen category of products.

Klaviyo also has similar functionality, but it’s a bit more complicated. First, you need to set up a product feed where you select the name for the feed, choose a catalog which should be included in the feed, decide what products should the customer view first, set up fallback settings, and then select categories. It allows for more control, but it also takes more time and configuration knowledge to do it.

It does, however, have more options for conditional and AI-driven product feeds like “products a customer may also like” alongside the regular best-sellers, most viewed products, and newest products. It’s a convenient option to use until you fully get the hang of the complexities Klaviyo comes with.

In short, both platforms allow you to add products to your emails, but Omnisend is generally more convenient to work with and doesn’t require any additional setups. One click adds the product you want, another click sets up dynamic product feeds.
Advanced segmentation tools
Rounding up your customers and subscribers into separate groups is called segmentation, and it’s an extremely powerful aspect not only of email marketing, but business in general. It allows you to send the right message to the right person at the right time. For example, you may want to give a special discount to people who haven’t bought anything in the last two months, but not to anyone else. Segmentation fixes that for you.
Both Omnisend and Klaviyo make it easy to create simple audience segments with their AI segmentation tools. You enter a prompt explaining what audience you want filtered, and the tools generate the segments in seconds. They’re not as capable for building complex segments, but for everyday subscriber segmentation they’re perfect.
Alternatively, both platforms also allow for manual creation of segments via their segmentation interfaces. Depending on your needs, there are tens of thousands (or even millions) of variations you can use to segment your contacts to your liking. Omnisend is a great solution for businesses with standard-advanced needs, but Klaviyo offers niche depth and control. For most businesses it’s an overkill, but there are some enterprises that have very specific segmentation needs.
In short, Omnisend is built with power and speed in mind that fulfills the needs of most modern online ecommerce stores, while Klaviyo has a major edge when it comes to highly-specific, data scientist-oriented setups.
SMS capabilities
SMS marketing involves sending text messages directly to the customer’s phone. While it’s a very fast and effective way to get someone’s attention, it must also be used cautiously. It’s a high-risk, high-reward method of sending promotions, so if you send SMS too often, you can get yourself blocked. But for those urgent messages about an occasional flash sale, this channel can convert several times better than just emails.
Omnisend supports SMS sending across the globe, which is perfect for international businesses operating beyond borders. As mentioned before, you can set up SMS messages to go out as part of your base automation workflow, so you don’t have to sit by the platform to make sure the campaigns go out on time. Just make sure you’re not abusing this feature as it’s a very delicate and sensitive thing to do. It’s one thing to send emails on a weekly basis, but sending SMS is highly intrusive and, in this case, less is more.
Klaviyo is limited to 18 countries only for SMS marketing, which is a massive setback for global brands. It does, however, have a feature called two-way messaging, which allows customers to text you back and have somewhat of a conversation. Omnisend doesn’t have this feature built-in, but you can add it through an integration with Gorgias.
For most brands, the most important message is getting the message out to as many people as possible, and Omnisend’s global reach makes it a stronger choice.
Pricing differences
Cost is a major factor when choosing a marketing platform for your store. In the earlier sections, you may have thought that Klaviyo is a better platform in some cases, but we specifically avoided talking about the price it comes with so we can do it here in more detail.
Omnisend is often more affordable than Klaviyo as your business grows. Its paid plans start at $16/month, while Klaviyo’s starts at $20/month. As your contacts list, along with your needs, start growing, the price gap can widen dramatically. For example, at 50,000 – 55,000 contacts, Omnisend’s base plan costs $450/month, whereas Klaviyo’s cheapest plan becomes $790/month.
What’s more, at that price, Omnisend provides a dedicated account expert just for you. Even without one, you have unrestricted access to 24/7 live chat and email support. Klaviyo, on the other hand, only gives you 24/5 live chat access (weekends not included) and 24/7 email access with a response time of 1-2 days.
Also, if you want the advanced features in Klaviyo like marketing analytics and Kalviyo Data Platform, you’ll have to pay additional $237 and $500, respectively at 50,000 – 55,000 contacts.
That’s not all. There’s still the matter of SMS. With Omnisend, you can buy SMS credits in small batches, and even if you don’t use them up, they roll over to the next month. Klaviyo locks the SMS credits behind expensive blocks, and if you fail to use them up before the month ends, you’ll lose them, as they don’t transfer them to the next month.
You don’t have to do the exact math to see that the price difference is massive. That’s why Omnisend is best for businesses of all sizes that don’t require niche capabilities. You get the same power presented in an intuitive interface, and everything’s more affordable at the same time.
If you do require the specific capabilities that Klaviyo offers, you need to think whether the price you pay is worth the ROI you’ll be getting.
Customer support
We mentioned customer support briefly in the pricing section, but there’s more information to know, so it warrants having its own section. Good support is essential when you have a problem with your marketing platform. On some occasions, it may be the defining line between driving revenue and losing sales.
Omnisend provides 24/7 live chat and email support, even on the free plan. You can get help day and night. They have won multiple awards for their helpful and fast customer service. The best part is that you’re not stuck trying to convince an AI bot to give you a human support agent. You can talk to a real person about your issues and get help in minutes. While professional marketers may not need this feature as much, it still provides reassurance that if something does break down, you won’t be left stranded.
Klaviyo also has high-quality support, but it’s more restricted compared to Omnisend. If you’re on the free plan, your deadline is 60 days. After that, you have to either upgrade your plan or search the help center for help. Once you do upgrade, there are several tiers of support response times, but live chat is still limited to business days on lower-tier plans.
For the cheapest plan, the response times are often 1-2 business days. If you upgrade even further to the highest tier, the response time drops to >12 hours, and live chat includes weekends (the plan does start at $1,800/month, though).
Aside from human support, both platforms also offer vast libraries of help center articles and YouTube videos. You can find solutions to nearly every problem in those resources, but be prepared to do some reading.
Migration opportunities
Moving your data between platforms is never a joyful task to do. There’s the risk of losing contacts, messing up your segments, rebuilding automations, redesigning templates, and more.
Omnisend makes it convenient for users to switch from competitors by providing a rather unique migration service. First, you need to meet one condition: sign up for a plan that exceeds $250/month. If that condition is met, they will dedicate an in-house specialist to handle the entire migration process for you.
That person will move your contacts, automations, templates, segments, forms, and verify your sender email within 5 business days, completely free of charge. You don’t need to worry about your data being lost or corrupted, and in just a few days you’ll be able to jump right into the action on your new platform.
Kalviyo often requires you to pay for onboarding if you want expert help. If you don’t, you’ll have to set everything up yourself using their migration documentation. If you have a very complex setup, it’s unlikely that you’ll be able to successfully replicate the data in another platform without help.
Omnisend vs. Klaviyo: Verdict
Both Omnisend and Klaviyo are excellent tools for ecommerce stores of all sizes, the main difference lies in the details and pricing.
Klaviyo is a top choice if you have a big budget and a team to manage it. It offers deep data that can help you understand every detail of your business. You get massive control over every part of the customer experience. This depth is great for the largest enterprises with very complex needs, but the depth and control comes at a steep learning curve and cost.
Omnisend is the better fit for most brands that want power without the high cost and technical overhead. It’s built to be fast, intuitive, and convenient while still remaining highly capable. You get 24/7 support and all the main tools you need for successful email marketing efforts. The free migration services also makes it easy to switch platforms without stressing out about potentially lost data.
Choosing between them depends on what you value most for your store. If you want to go deep with data and don’t mind the price, Klaviyo is the best you can get. If you want a growth-focused and affordable platform, Omnisend is usually the smarter pick. Both tools have high ratings and happy customers across the world. Also, they both integrate easily with platforms like Shopify and WooCommerce, so you won’t have to do any manual coding.
In the end, the best way to decide is to try both tools for yourself. You can sign up for free accounts and see which dashboard and features feel better. Look at the templates, the automation builders, segmentation capabilities, tag systems, and more to see which fits your needs better.
Think about where your customers are based and if you need global SMS reach. Also, consider how much help you might need and if 24/7 support is important to you. Doing the research and making an informed choice now will ensure that your email marketing operates smoothly in the future without the need to look for alternatives.
