Omnisend Review
Shopify sellers who want email and SMS marketing with AI features at a lower price than Klaviyo
Last updated 2026-04-02
Our verdict
The best value email and SMS platform for Shopify stores. You get nearly every feature on the free plan, and the AI tools are practical rather than gimmicky.
What is Omnisend?
Omnisend is an email and SMS marketing platform built for e-commerce, with deep Shopify integration and AI features across every pricing tier including free. It occupies the same space as Klaviyo but at a significantly lower price point, making it the go-to choice for Shopify sellers who want marketing automation without a large upfront investment. Over 150,000 brands use Omnisend, and it holds a 4.8 rating on the Shopify App Store.
Key features
The standout feature is the AI segment builder, which lets you create audience segments using natural language. Type something like 'customers from London who spent over 50 pounds in the last 60 days' and it builds the segment for you. The AI subject line generator creates variations for testing, though it lacks the tone controls you get with Klaviyo. Product recommendation blocks use browsing and purchase data to personalise emails automatically. Pre-built automation workflows for welcome sequences, abandoned carts, and post-purchase follow-ups are ready to activate in minutes. SMS and email live in the same platform, so you can build workflows that use both channels without paying for a separate SMS tool.
How it performs
For the price, Omnisend punches well above its weight. The free plan includes automation, segmentation, and AI features that competitors lock behind paid tiers. The Standard plan at $16 per month for 500 contacts is roughly half what Klaviyo charges at the same list size. Predictive send-time optimisation works well in practice, and the AI segment builder saves genuine time once your list grows. The main gap compared to Klaviyo is in predictive analytics depth. Klaviyo's customer lifetime value predictions and churn scoring are more sophisticated. If advanced data modelling drives your email strategy, Klaviyo justifies the premium.
Who should use Omnisend?
Omnisend is the right choice for Shopify sellers who want serious email and SMS marketing without Klaviyo's price tag. The free plan is generous enough to validate the platform properly before spending anything. If you are under 2,500 contacts, the Standard plan at $16 per month delivers exceptional value. Consider upgrading to Klaviyo only if you need deeper predictive analytics or your list has grown past 10,000 contacts where the pricing gap narrows. For Amazon-only sellers, neither Omnisend nor Klaviyo offer meaningful value since you cannot email Amazon customers directly.
