Two of the most popular tools in 2025 are Klaviyo and Omnisend, both trusted by thousands of online stores worldwide. But which one truly delivers more revenue for your business?
In this comparison, we’ll break down Klaviyo vs Omnisend across features, pricing, ease of use, and sales impact. Whether you’re a Shopify entrepreneur, a mid-sized online retailer, or scaling to enterprise level, knowing which platform fits your needs will save you time, money, and lost opportunities.
Let’s dive into the details to help you decide which platform will actually drive more sales.
Klaviyo vs Omnisend Overview
Choosing the right email and SMS marketing automation tool can make or break an eCommerce business in 2025. With customer acquisition costs rising and retention becoming the true driver of growth, platforms like Klaviyo and Omnisend have emerged as two of the most popular marketing solutions for online stores. Both tools promise advanced automation, deep integrations, and measurable sales impact—but their approaches and strengths differ.
Klaviyo was founded in 2012 and quickly became a market leader by offering advanced segmentation, personalization, and predictive analytics. Known as the go-to solution for Shopify and other eCommerce stores scaling beyond six figures, Klaviyo is often praised for its depth and ability to turn customer data into actionable campaigns. By 2025, Klaviyo reports powering more than 140,000 businesses worldwide, including high-growth direct-to-consumer brands.
Omnisend, launched in 2014, positioned itself as a more accessible and beginner-friendly automation platform. It focuses on simplicity, affordability, and speed to ROI, making it especially popular among small to mid-sized online stores. With over 100,000 active users in 2025, Omnisend has built a strong reputation by offering ready-to-use workflows, omnichannel messaging (email, SMS, push notifications), and competitive pricing that appeals to growing merchants who don’t want complexity slowing them down.
From a market adoption standpoint in 2025, Klaviyo is still considered the enterprise-favorite with a strong foothold among larger retailers, while Omnisend has captured a loyal user base among independent merchants, Shopify sellers, and regional eCommerce businesses that value simplicity and cost efficiency.
In short, while both Klaviyo and Omnisend are powerful tools, the choice between them depends on whether your priority is scaling with data-driven precision (Klaviyo) or growing faster with affordable, ready-made marketing flows (Omnisend).
“Choosing between Klaviyo and Omnisend isn’t just about email—it’s about unlocking the platform that truly drives your eCommerce sales growth.”
Features That Drive Sales
When evaluating Klaviyo vs Omnisend in 2025, the real question is which features directly impact sales. Both platforms provide the essential tools for email marketing automation and SMS campaigns, but their strengths and depth differ. Let’s break down the key features that matter most for driving revenue.
Email Marketing Automation
Email automation remains the backbone of both Klaviyo and Omnisend.
Klaviyo is known for its data-driven automation flows that allow merchants to create highly personalized journeys. From abandoned cart reminders to post-purchase upsells, every trigger can be tailored using advanced customer data like purchase history, browsing behavior, and predicted lifetime value. This makes Klaviyo the choice for brands that want to squeeze every dollar out of customer retention.
Omnisend, by contrast, shines with pre-built workflows. Instead of requiring deep setup, Omnisend provides ready-to-launch automation for common eCommerce scenarios: cart abandonment, welcome series, product recommendations, and re-engagement. This plug-and-play approach saves time for busy store owners while still ensuring campaigns are optimized to recover sales.
SMS Marketing Comparison
SMS marketing has become non-negotiable in 2025 as customers demand real-time, mobile-first communication.
Klaviyo SMS is deeply integrated with its email platform, making it easy to orchestrate multi-channel flows (for example: email → SMS → email). However, its SMS costs are typically higher, and it has stronger support for U.S.-based campaigns.
Omnisend SMS offers more affordable global messaging, making it attractive for stores with international audiences. Merchants can send texts at lower rates while still benefiting from automation flows that combine SMS, email, and even push notifications.
Segmentation and Personalization
Targeted messaging drives higher revenue per recipient.
Klaviyo dominates in this area. Merchants can create micro-segments based on hundreds of data points—such as how often someone browses without buying, their average order value, or whether they prefer certain product categories. This level of personalization ensures higher open and conversion rates.
Omnisend keeps things simpler with dynamic segments based on behavior, purchase history, and engagement. While not as advanced as Klaviyo, it offers enough flexibility for most small to mid-sized businesses to send relevant messages without complexity.
AI and Predictive Analytics
Artificial intelligence is transforming marketing automation in 2025.
Klaviyo AI tools include predictive analytics that forecast customer lifetime value, churn probability, and optimal send times. For data-driven brands, this translates into smarter targeting and increased ROI.
Omnisend AI features are lighter, focusing on product recommendation blocks and send-time optimization. While not as advanced as Klaviyo’s machine learning models, they deliver practical insights for stores that don’t want to get lost in analytics dashboards.
Integrations with eCommerce Platforms
No marketing tool works in isolation—seamless integration with your store is critical.
Klaviyo integrates deeply with Shopify, BigCommerce, WooCommerce, Magento, and Salesforce Commerce Cloud, as well as payment systems and third-party analytics tools. Its Shopify partnership is especially strong, offering merchants robust reporting and one-click data sync.
Omnisend also integrates with Shopify, WooCommerce, Wix, Prestashop, and BigCommerce, plus dozens of third-party tools. Its setup process is quicker, making it appealing for new store owners who want to get campaigns live without technical hurdles.
Ease of Use and User Experience
The effectiveness of a marketing automation platform doesn’t just depend on features—it also depends on how easily users can put those features into action. A tool that looks powerful on paper but is difficult to use can slow down campaigns and frustrate teams. Here’s how Klaviyo and Omnisend compare in terms of usability in 2025.
Dashboard and Workflow Design
Klaviyo has a professional, data-heavy dashboard designed for marketers who want granular control. Every metric, from revenue per campaign to customer lifetime value, is visible at a glance. Its flow builder offers near-unlimited customization, allowing merchants to design journeys with multiple conditions and branches. However, this complexity can sometimes feel overwhelming, especially for newcomers.
Omnisend, by contrast, is built for simplicity. Its interface is clean, intuitive, and beginner-friendly, focusing on drag-and-drop workflows. Merchants can quickly select a pre-made automation (such as “welcome series” or “cart recovery”), tweak a few settings, and launch without spending hours learning the system. For store owners who prioritize speed, Omnisend provides a smoother entry point.
Learning Curve for Beginners
Klaviyo has a steeper learning curve. While advanced users love its powerful segmentation and customization, beginners often report that setup requires patience and time. Brands with dedicated marketing teams tend to get the most value, as they can fully utilize its data capabilities.
Omnisend is widely considered easier for first-time users. The platform’s focus on ready-to-use automation, drag-and-drop email templates, and guided onboarding makes it accessible even for non-technical store owners.
Support and Onboarding
Klaviyo provides comprehensive documentation, community forums, and live chat support. Its onboarding process includes training sessions and strategy advice for premium customers, which is valuable for scaling businesses. However, some smaller merchants find the support tiered—meaning advanced help often comes with higher pricing plans.
Omnisend has built its reputation on responsive customer support, often praised for its fast replies and practical guidance. The onboarding includes step-by-step tutorials, video guides, and free migration assistance for new customers. Many users note that Omnisend feels more “hands-on” when helping small to mid-sized businesses get started.
Pricing Comparison 2025
Pricing is one of the most decisive factors when comparing Klaviyo vs Omnisend. Both platforms operate on a subscription-based model that scales with the size of your contact list and usage of SMS credits. However, their cost structures diverge significantly in 2025, influencing which tool offers better value depending on business stage and growth goals.
Klaviyo Pricing Breakdown
Klaviyo is considered a premium marketing platform, and its pricing reflects the depth of features offered.
- Free Plan: Available for up to 250 contacts and 500 monthly email sends, ideal for trial but too limited for real campaigns.
- Email-Only Plans: Start at around $45/month for 1,000 contacts and scale upward. A store with 10,000 contacts typically pays about $150–$180/month, while 50,000 contacts can exceed $700/month.
- Email + SMS Plans: Costs increase further when adding SMS. Pricing varies by country, with U.S. SMS messages costing more than international rates. Many merchants allocate an additional $20–$100+ per month for SMS credits depending on volume.
Klaviyo justifies its higher costs with advanced segmentation, predictive analytics, and enterprise-grade integrations. It’s often the choice for businesses generating six-figure or seven-figure revenues where ROI outweighs upfront cost.
Omnisend Pricing Breakdown
Omnisend positions itself as the more affordable alternative, particularly appealing to small and mid-sized merchants.
- Free Plan: Up to 250 contacts and 500 monthly emails, similar to Klaviyo.
- Standard Plan: Starts at $20/month for 1,000 contacts, significantly cheaper than Klaviyo. A store with 10,000 contacts pays about $100/month, while 50,000 contacts typically costs $400–$450/month—almost half the price of Klaviyo at scale.
- SMS Pricing: Omnisend offers more competitive SMS rates, with credits included in higher tiers and cheaper international delivery compared to Klaviyo. Merchants with global audiences often find Omnisend’s SMS pricing far more sustainable.
Omnisend’s pricing is designed to make automation accessible without overwhelming smaller stores. Its balance of affordability and features allows merchants to launch professional campaigns without needing enterprise budgets.
Which Offers Better Value at Scale
The choice between Klaviyo and Omnisend pricing comes down to business size and priorities:
- Klaviyo delivers more advanced features, but costs rise steeply as your list grows. For enterprise-level brands with large budgets, the ROI from Klaviyo’s predictive analytics and data-driven targeting usually justifies the higher spend.
- Omnisend offers better value-for-money for small and mid-sized stores, providing strong automation and omnichannel features at roughly 40–50% lower cost than Klaviyo at scale. For businesses focused on quick ROI without complex setup, Omnisend wins on affordability.
Sales Performance Insights
At the end of the day, marketing tools are judged not just by their features but by the sales results they deliver. In 2025, both Klaviyo and Omnisend have strong track records of boosting eCommerce revenue, but their methods and outcomes vary depending on the type of business using them.
Revenue per Recipient (RPR) Benchmarks
One of the clearest ways to measure sales effectiveness is revenue per recipient (RPR)—the average amount of money earned per customer email sent.
- Klaviyo often reports a higher RPR, especially for brands that rely heavily on segmentation and personalization. Advanced triggers like predicted churn or product affinity recommendations mean campaigns reach the right customers at the right time. Many mid-market and enterprise stores report 15–20% higher RPR compared to when using other tools.
- Omnisend delivers consistent results with its pre-built workflows. While its RPR averages slightly lower than Klaviyo, the difference is often offset by faster setup and quicker time-to-value. Small to mid-sized merchants frequently see 10–15% lifts in overall sales within the first 90 days of switching to Omnisend, even without heavy customization.
Conversion Rate Optimization Tools
Both platforms provide tools designed to increase conversions across campaigns:
- Klaviyo: Strong A/B testing, predictive analytics, and personalized product feeds help merchants refine every step of the customer journey. Advanced features like “smart send time” and AI-driven product recommendations further boost conversion rates.
- Omnisend: Focuses on simplicity with ready-made popups, discount code integrations, and cart recovery automations that are optimized out-of-the-box. It may not offer the same granular control as Klaviyo, but it ensures merchants can implement conversion best practices without needing a dedicated marketing analyst.
Case Studies and Success Stories
- A fashion retailer using Klaviyo leveraged predictive analytics to identify high-value customers at risk of churn. By launching a win-back series targeting these shoppers, the brand recovered 22% of potential lost revenue within three months.
- An independent beauty store on Omnisend implemented pre-built workflows for welcome emails, cart recovery, and cross-sells within the first week of setup. The result was a 28% increase in monthly sales and a 2.5x ROI on their subscription fee in the first quarter.
Which Platform Should You Choose?
Deciding between Klaviyo vs Omnisend in 2025 comes down to your business size, resources, and growth strategy. Both platforms are excellent, but their strengths align with different types of merchants.
Best for Small to Mid-Sized Stores
If you are running a small to mid-sized eCommerce business, Omnisend is generally the better fit. Its affordable pricing, beginner-friendly interface, and ready-to-use automation make it easy to launch effective campaigns quickly. Store owners don’t need advanced technical knowledge or large marketing teams to see results. Omnisend is especially appealing if your focus is on:
- Affordable SMS campaigns with global reach

Best for Enterprise-Level Growth
For fast-scaling or enterprise-level brands, Klaviyo remains the top choice. Its data-driven personalization, predictive analytics, and advanced integrations give larger businesses the ability to maximize revenue per customer. While the pricing is higher, the investment pays off for brands with large audiences and dedicated teams to fully utilize the features. Klaviyo is especially suited for:
- Brands with 50,000+ contacts
- Stores investing heavily in customer retention strategies
- Teams with analysts and marketers who can build advanced segments
- Businesses wanting deep insights into customer lifetime value and churn risk

A closer look at real-world performance, hard data, and user perspectives reveals why.
