Omnisend vs Klaviyo: Simpler Setup vs Deeper Data

Omnisend and Klaviyo both built their entire product around ecommerce, mostly Shopify, with email, SMS, and automation workflows baked in instead of bolted on. The real difference isn't which one sends a better-looking email. It's how much segmentation depth you want and how much you're willing to pay as your list grows. And either way, neither one knows what's happening in the rest of your business beyond the storefront.

Where they actually differ

Omnisend leans toward simplicity and value: a flatter learning curve, SMS and push notifications bundled in from lower-tier plans, and pricing that tends to stay more predictable as a list grows. Its automation workflows come pre-built for the common ecommerce cases, cart abandonment, welcome series, post-purchase, so a store can get something useful running fast.

Klaviyo leans toward depth: more granular segmentation, predictive analytics like estimated customer lifetime value, and a larger app ecosystem built up over years of being a default choice for larger, more data-heavy DTC brands. That depth comes with a steeper learning curve and pricing that climbs faster once a list gets large.

The practical split: a smaller or newer store that wants SMS, email, and automation working together without much setup tends to land on Omnisend. A larger store with a dedicated marketer who wants to build complex, data-driven segments tends to land on Klaviyo, and usually has budget set aside for it.

What matters more than picking one

n-frames doesn't sell either platform, so there's no side to take here. What we actually see, across stores running either one, is that the marketing platform is rarely the real ceiling. The ceiling is that Omnisend and Klaviyo both only know what your store platform tells them: orders, customers, products. Ask either one to segment by loyalty tier, wholesale status, or a support ticket that's still open, and it's blind unless something else feeds it that data.

That gap exists on both platforms, and switching from one to the other doesn't close it, it just moves which marketing tool the gap sits behind. We build on top of Omnisend →: pulling in inventory, loyalty, and account data the native Shopify connector doesn't carry, and triggering actions outside the platform when a workflow finishes. If you're already running either one and segmentation still feels shallow, the fix is usually connecting it properly, not migrating to the other one.

Already running Omnisend or Klaviyo and still can't segment on the data that actually matters?

Tell us what your segments are missing, loyalty status, wholesale accounts, support history, whatever your store platform doesn't hand either tool by default. Switching platforms rarely fixes that. Connecting the one you've already got to the data you're missing usually does, and we can tell you what that actually involves.

Frequently Asked Questions

Is Omnisend cheaper than Klaviyo?+
Generally yes, especially as your contact list grows. Omnisend's pricing tends to stay more predictable at scale, while Klaviyo's cost climbs faster past the free tier, partly because you're paying for the deeper segmentation and analytics underneath it. Exact pricing on both moves often enough that omnisend.com/pricing and klaviyo.com/pricing are the only sources worth trusting.
Does Omnisend have a free plan like Klaviyo?+
Both offer a genuine free tier for a small contact list and limited sends, which is part of why they get compared so often. Neither free tier is built to run a real store's marketing long-term; they're there to get you started and prove the product out.
Which one is better for a small Shopify store just starting out?+
Omnisend tends to fit that case well: SMS and automation come bundled in earlier, and setup is quick enough to have something running the same day. If you already know you'll want deep, predictive segmentation as you grow, Klaviyo's extra depth might be worth the steeper start.
Can I migrate my lists and automations from Klaviyo to Omnisend, or the other way around?+
Yes, both support importing contacts and rebuilding automations, and it's a real but manageable project for most stores. The bigger cost usually isn't the migration itself, it's redoing any custom segmentation logic that depended on the platform you're leaving.
We're happy with our ESP but our segments still feel basic. Do we need to switch to the other one?+
Almost never. That's usually a data problem, not a platform problem, and it shows up on Omnisend and Klaviyo alike: both only know what your store platform syncs over by default. The fix is usually feeding in the data that's missing, not re-platforming to the other tool.
