Klaviyo is the better fit for growing Shopify and DTC brands that want the deepest data and email plus SMS on one profile, while Omnisend suits small stores that want strong ecommerce automation at a lower price. Both connect to your store, offer free plans for up to 250 contacts, and ship with the core flows every store needs. The gap shows up in data depth, SMS packaging, and how fast the bill grows.

Think of the choice as depth versus simplicity. Klaviyo gives a growing brand more data, more channels on one profile, and more room to test, but it asks for more setup and costs more as the list grows. Omnisend covers the flows that drive most ecommerce email revenue, adds web push, and keeps the bill and the learning curve lower. Below, we compare them on what ecommerce marketers weigh most.

Automation and segmentation

Klaviyo is built around store data. It pulls order, browsing, and product data from your store and uses it for segments, flows, and product recommendations across email and SMS. Predictive analytics add fields such as expected next order date and predicted lifetime value, and A/B testing works across channels. For a brand with a large catalog and repeat buyers, that depth turns into sharper targeting.

Omnisend covers the core ecommerce flows well, with prebuilt automations for welcome, cart abandonment, browse abandonment, and post-purchase. Its segmentation handles the common cases, such as buyers versus non-buyers and purchase history. Pro adds an AI product recommender and dynamic content personalization. It has fewer advanced analytics than Klaviyo, but most small stores will not miss them.

Winner: Klaviyo. Its data model and predictive features go further, which matters more as your list and catalog grow.

Email builder and ease of use

Omnisend is simpler to pick up. Its drag-and-drop builder, signup forms, and popups are quick to set up, and the prebuilt automations let a small team launch working flows in an afternoon. There are fewer settings to get lost in.

Klaviyo’s builder and template library are strong, with more than 160 campaign templates, but the platform has more settings than a small store needs. That flexibility is the point for a growing marketing team. For a solo founder, it can slow the first few weeks.

Both offer signup forms and popups to grow your list, so neither leaves you shopping for a separate form tool on day one.

Winner: Omnisend. It is faster to learn and easier to run without a dedicated marketer.

SMS and other channels

Klaviyo sells SMS separately from email, starting at $15 a month for up to 1,250 SMS and MMS credits, with carrier fees included. Two-way conversations, transactional SMS, and branded links are part of the package. Because email and SMS share one profile and one report, you can see which channel drove each order and coordinate messages across both.

Omnisend does not offer SMS on Standard. You need the Pro plan, which starts at $59 a month, then an SMS credits subscription with rates as low as $0.007 per message depending on spend and country. Unused credits expire after 60 days. On the plus side, both Standard and Pro include unlimited web push notifications, which gives stores another low-cost way to reach browsers who have not shared an email or phone number.

Winner: Klaviyo. SMS starts at a lower total price, includes carrier fees, and shares one profile with email. Omnisend earns credit for including web push.

Pricing and total cost

Both have free plans with 500 email sends a month. Klaviyo’s free plan covers 250 active profiles, and Omnisend’s covers 250 contacts. On the Shopify App Store, Klaviyo Email starts at $20 a month for 251 to 500 contacts. Its main pricing page uses an estimator rather than a fixed price list, so model your cost at your current profile count, since the price rises fast as the list grows.

Omnisend Standard starts at $16 a month for up to 500 contacts, with email sends capped at 12 times your contact count each billing cycle. Pro starts at $59 a month at 2,500 contacts, with unlimited email under a fair use policy. Omnisend bills on billable contacts, which include non-subscribers and exclude only unsubscribes, so clean your list before you import. New paid customers can get a starter discount for their first three months.

Winner: Omnisend. Its email pricing is lower at entry and stays easier to predict as a small list grows. A brand that needs SMS should price both carefully, since Omnisend’s Pro requirement can erase the gap.

Reporting and attribution

Klaviyo’s reporting is one of its strongest features. Email and SMS share one profile and one report, so you can compare channels, flows, and campaigns side by side, and its predictive analytics feed segments as well as dashboards. The Shopify app also lists a built-in dashboard and send time optimization, which helps teams find the hours their customers engage most.

Omnisend includes standard campaign and automation reports on every plan, and Pro adds advanced reporting. That covers what most small stores check each week: revenue by flow, click rates, and unsubscribes. It has fewer advanced analytics than Klaviyo, so brands that want deep cohort or predictive analysis will feel the limit sooner.

On either platform, compare reported revenue against your store’s own sales data. Attribution windows can credit an order to a message the buyer barely noticed, so use platform numbers to compare flows, not to judge total marketing return.

Winner: Klaviyo. Unified email and SMS reporting and predictive data give growing teams more to act on.

Integrations

Klaviyo lists more than 350 integrations. On Shopify, it works with Checkout, customer accounts, and Shopify Flow, and connects to tools such as Gorgias, Recharge, Aftership, and Meta and TikTok advertising. That breadth lets you trigger flows from subscriptions, support tickets, and reviews, and sync audiences to ad platforms.

Omnisend lists more than 250 integrations, including Shopify Flow, Gorgias, Recharge, Yotpo, Loox, Justuno, and Aftership. That covers the common Shopify stack well.

Winner: Klaviyo. A larger integration library and ad platform connections give it the edge for brands with a busy tech stack.

Support

Omnisend offers 24/7 email and live chat support, even on the free plan, and adds a dedicated account expert on plans of $400 a month or more. For a small team without a marketing specialist, round-the-clock help is a real advantage.

Klaviyo offers guided onboarding, help documentation, and tutorials, plus a large partner and agency network for brands that want outside help. Its support is solid, but it does not advertise round-the-clock live chat on the free plan the way Omnisend does.

Winner: Omnisend. 24/7 live chat on every plan is hard to beat for a small store.

Which one should you pick?

Pick Klaviyo if you run a growing Shopify or DTC brand, want deep segmentation and predictive analytics, and plan to use SMS alongside email. Pick Omnisend if you run a smaller store, want strong prebuilt automation and web push at a lower price, and do not need SMS yet. If you want an SMS-first tool or something simpler, our ranked list of the best email and SMS marketing platforms for ecommerce covers Attentive, Postscript, Drip, and Mailchimp too.
