Omnisend Review

Shopify sellers under 50K contacts who want email, SMS, and push notifications in one affordable platform

Last updated 2026-04-03

Our verdict

Omnisend is the best value email and SMS platform for Shopify stores that do not need enterprise-level analytics. You get 90% of what Klaviyo offers at roughly half the price, with a genuinely useful free plan. The deliverability concern is real but manageable with good list hygiene. If you are doing under $50K per month and your list is under 50K contacts, Omnisend is the smarter starting point. Move to Klaviyo only when you need predictive analytics or outgrow the platform.

What Does Omnisend Do?

Omnisend is an email and SMS marketing platform built for e-commerce, competing directly with Klaviyo at a lower price point. It integrates natively with Shopify and covers email campaigns, SMS messages, web push notifications, and marketing automation in one subscription.

The platform includes 27 pre-built automation workflows covering the full e-commerce lifecycle: welcome series, abandoned cart recovery, browse abandonment, post-purchase follow-ups, and win-back campaigns. The AI segment builder lets you describe audience segments in plain English and builds them automatically.

Omnisend's pricing model differs from Klaviyo in one key way: every feature is available on every plan, including the free tier. You only pay more as your contact list grows or when you want advanced reporting on the Pro plan.

What Features Did We Test?

AI segment builder

Best in category

Type a plain English description like 'customers in London who spent over 50 pounds in the last 60 days' and Omnisend builds the segment automatically. No filters or dropdown menus needed. Faster and more intuitive than any competitor's segmentation tool.

Pre-built automations

Works well

27 automation workflows covering welcome, abandoned cart, browse abandonment, post-purchase, and win-back. One-click activation with sensible defaults. Saves hours compared to building flows from scratch.

Email builder

Works well

Drag-and-drop editor with product picker that pulls directly from your Shopify catalogue. Templates are clean and mobile-responsive. Product recommendation blocks personalise content based on browsing and purchase history.

SMS marketing

Works well

SMS and email live in the same platform with unified contact profiles. You can mix email and SMS steps in a single automation flow. Credits are included in paid plans rather than billed separately.

AI subject line generator

Acceptable

Generates subject line variations for A/B testing. Functional but basic compared to Klaviyo's tone and context controls. It works for quick ideas but you will often write better subject lines yourself.

Deliverability

Needs work

Independent tests have measured deliverability rates of 64-75%, below top competitors. The shared IP infrastructure means your sender reputation is partly dependent on other Omnisend users. No dedicated IP option is available.

What Does Omnisend Do Well?

+

Price vs features

At 5,000 contacts, Omnisend Standard costs roughly $81/month compared to $100/month for Klaviyo. Every feature is available on every plan including free, with no paywalled tiers.

+

All-in-one messaging

Email, SMS, and web push notifications in one platform with unified contact profiles. You do not need separate tools or separate subscriptions for each channel.

+

Free plan generosity

The free plan includes automation, segmentation, AI tools, and SMS credits. Competitors typically lock these behind paid tiers. You can validate the platform fully before spending anything.

+

Ease of use

The interface is cleaner and simpler than Klaviyo. Pre-built automations with one-click activation make it accessible for sellers who do not want to spend days configuring email flows.

Where Does Omnisend Fall Short?

-

Deliverability concerns

Independent tests show 64-75% deliverability rates, below competitors like Klaviyo. Shared IP infrastructure means your reputation depends partly on other senders. Good list hygiene helps, but this is a real limitation.

-

No predictive analytics

No customer lifetime value prediction, churn risk scoring, or next-order-date forecasting. If your email strategy depends on predictive data models, Klaviyo is the only option in this price range.

-

Scaling issues above 50K contacts

Users report performance issues and slower campaign sends at higher list sizes. No dedicated IP option means you cannot control your sender reputation as the list grows.

-

Basic A/B testing

A/B testing is limited to subject lines and send times. No native dynamic content personalisation beyond merge tags. For advanced testing strategies, this is a limitation.

Who Should Use Omnisend?

Shopify stores under 50,000 contacts

This is Omnisend's sweet spot. The pricing advantage over Klaviyo is largest at these list sizes, and the feature set covers everything most stores need.

Sellers who want email and SMS in one tool

Unified email and SMS with shared contact profiles and mixed automation flows. No need to manage two platforms or pay for a separate SMS subscription.

Budget-conscious stores that want automation

The free plan includes full automation and segmentation. No other email platform at this price point offers comparable automation capabilities on the free tier.

Who Should Avoid Omnisend?

Data-driven stores that rely on predictive analytics

If CLV prediction, churn scoring, and predictive send-time optimisation are central to your email strategy, Omnisend does not offer these. Klaviyo is the better fit.

Stores with lists above 50,000 contacts

Scaling issues and the lack of a dedicated IP option make Omnisend less reliable at large list sizes. Klaviyo handles high-volume sending more consistently.

Brands where deliverability is critical

If your business depends on every email reaching the inbox (e.g. transactional, time-sensitive offers), the deliverability gap is a real risk. Test carefully before committing.
