Klaviyo vs Omnisend: Which is Better for Ecommerce in 2025?

Deciding on the right email marketing platform can feel like a make-or-break moment for your business. Trust me, I’ve been there. After testing both Omnisend and Klaviyo extensively with several ecommerce clients, I’ve seen firsthand how each platform can dramatically impact customer engagement — for better or worse.

Klaviyo has built its reputation on being the data powerhouse of email marketing. It’s the platform that data-obsessed marketers tend to gravitate toward, with its deep integrations and almost surgical precision when it comes to segmentation. My clients who live and breathe analytics usually can’t get enough of it.

Omnisend, meanwhile, has carved out its niche by being remarkably user-friendly while still packing a punch with features like built-in SMS and push notifications. I’ve found it’s often the preferred choice for teams who need to launch campaigns quickly without spending weeks in training sessions.

But which one deserves your marketing budget? Let’s dive into the nitty-gritty details to help you make that call.

Klaviyo vs Omnisend — Feature Comparison

Omnisend: Streamlined Multi-Channel Marketing

I’ve set up Omnisend for several smaller ecommerce businesses, and what consistently impresses them is how quickly they can get campaigns off the ground. The platform feels designed for marketers who need results without the technical overhead.

Omnisend’s real strength lies in making omnichannel marketing accessible. You don’t need separate platforms for email, SMS, and push notifications — everything works together seamlessly. For busy ecommerce teams juggling multiple responsibilities (and isn’t that all of us?), this integrated approach can be a genuine time-saver.

The pre-built workflows deserve special mention. Rather than starting from scratch, you can implement proven sequences for welcome series, abandoned carts, and post-purchase follow-ups with just a few clicks. One client saw a 15% revenue boost within weeks just from activating these ready-made automations.

Klaviyo: The Data-Driven Marketer’s Dream

When I’ve implemented Klaviyo for clients, the initial reaction is often a mix of intimidation and excitement. There’s a definite learning curve, but those who push through it gain access to marketing capabilities that are genuinely impressive.

Klaviyo excels at turning customer data into personalized marketing opportunities. The segmentation engine lets you target customers based on incredibly specific behaviors — not just “people who bought product X,” but “people who viewed product X multiple times, added it to cart, but purchased product Y instead.” That level of granularity helps create remarkably relevant messaging.

The predictive analytics also deserve attention. Klaviyo can forecast customer lifetime value and recommend logical next purchases, helping you prioritize your highest-value audience segments. For ecommerce brands serious about scaling through data-driven marketing, these capabilities often justify the higher price tag.

Klaviyo vs Omnisend — Pricing Reality: What You’ll Actually Pay

Pricing Summary

Looking at these numbers, the pricing difference becomes impossible to ignore. I’ve had extensive conversations with clients about this very table, and the decision often comes down to how they value data sophistication versus cost efficiency.

Omnisend maintains a more affordable approach across all subscriber tiers while bundling in SMS and push notifications — channels that Klaviyo treats as separate add-ons. For businesses watching their budget (and who isn’t?), this integrated pricing model often tips the scales.

Klaviyo’s steeper pricing reflects its position as a premium tool for serious data-driven marketing. As businesses grow and their strategies become more sophisticated, the advanced segmentation and predictive features can deliver ROI that justifies the higher cost. I’ve seen this transformation happen with several clients who initially balked at Klaviyo’s pricing but eventually migrated as their needs evolved.

Klaviyo vs Omnisend — Free Options

Free Plan Reality

I often recommend that new clients start with the free plan of whichever platform seems most aligned with their needs. Both are surprisingly capable without spending a dime, though they come with identical send limits and subscriber caps.

Omnisend’s free tier includes access to their multi-channel tools and user-friendly templates. This makes it perfect for small stores that want to experiment with different messaging channels without financial commitment. One boutique clothing client used the free plan for three months before upgrading, and still managed to generate enough revenue to justify the eventual paid subscription several times over.

Klaviyo’s free offering focuses more on data-driven email capabilities. You get the core segmentation features and behavior-based triggers, which can be powerful even with the limited send volume. It’s ideal for businesses that want to test Klaviyo’s approach to personalization before investing in a paid plan.

Both free plans include rather obvious platform branding and cap you at 250 contacts, so they’re clearly designed as starting points rather than long-term solutions.

Klaviyo vs Omnisend — Pros & Cons

Omnisend: Practical Simplicity

After implementing Omnisend for multiple clients, I’ve come to appreciate its practical approach to ecommerce marketing. It doesn’t try to be everything to everyone — instead, it focuses on making multi-channel marketing accessible and effective.

The platform shines brightest when you need to get campaigns running quickly without a lengthy setup process. One client switched from a more complex platform and launched their first automation sequence within hours, not days.

Omnisend’s built-in SMS and push notifications deserve special mention. Having these channels integrated with email marketing creates a cohesive customer experience without the headache of managing multiple platforms. For teams with limited resources, this streamlined approach can be a genuine lifesaver.

Where Omnisend falls short is in handling extremely complex segmentation or data manipulation. If your marketing strategy relies on sophisticated behavioral analysis or predictive modeling, you might eventually hit some limitations.

Klaviyo: Data-Driven Powerhouse

Klaviyo approaches email marketing from a fundamentally different angle — it’s built from the ground up for businesses that want to leverage customer data to drive personalization and revenue growth.

Its greatest strength lies in the depth of its segmentation and automation capabilities. You can create incredibly specific customer segments based on purchase history, website behavior, email engagement, and predictive metrics. This precision allows for highly targeted messaging that consistently delivers better open rates, click-throughs, and conversions.

The platform’s ecommerce integrations go beyond basic functionality, pulling in detailed product and transaction data that powers its personalization features. For stores with large product catalogs and complex customer journeys, this depth of integration proves invaluable.

The trade-offs are clear: higher cost, steeper learning curve, and potential feature overwhelm for simpler use cases. I’ve had clients take weeks to fully grasp Klaviyo’s capabilities, though most eventually felt the time investment was worthwhile.
