Email is one of the most profitable channels a Shopify store has: across our client stores it is a median 30% of revenue. So the choice of email platform matters, and Omnisend is one of the names that comes up most often when store owners look for something more affordable than Klaviyo or more ecommerce focused than Mailchimp.

What Is Omnisend?

Omnisend is an email and SMS marketing platform built for ecommerce. It connects to your Shopify store, pulls in customers, orders and products, and lets you send campaigns and automated messages based on what shoppers do. Web push notifications are part of the package too.

Its Shopify app had a rating of 4.7 stars from 3,188 reviews when we checked on 15 October 2026, and lists welcome, abandoned cart and post purchase workflows, exit intent pop ups and signup forms, segmentation, and Shopify Flow among its features.

Omnisend Pricing for UK Stores

Omnisend's pricing page bills in US dollars; the pound figures it shows are estimates. Prices depend on how many contacts you have, and the three plans start at these list sizes:

Three details change what you actually pay:

• Paying upfront. Paying three months in advance takes 30% off, which brings the starting prices down to $11.20 and $41.30 a month.
• Who counts as a contact. Omnisend bills for subscribers and for non subscribers who received automated messages, but not for unsubscribed contacts.
• SMS. Texts are charged per message, and Omnisend says the price varies by country and volume. UK rates are not the US rates shown first on the page.

Above 150,000 active profiles, Omnisend quotes custom pricing. For a comparison with Klaviyo's plans, see our Klaviyo pricing guide.

Omnisend Features for Shopify Stores

Automations

Omnisend's pre built workflows cover the flows that earn most of the money in ecommerce email: welcome, abandoned cart, browse abandonment and post purchase. Across our Klaviyo clients, the welcome series and abandoned cart and checkout flows are normally the best performing flows by revenue and conversion rate, and the same pattern holds whatever platform sends them. Email, SMS and push can be combined in one workflow.

Forms and pop ups

Pop ups, exit intent forms and embedded signup forms collect email and SMS subscribers. Our guide to getting more email subscribers covers the offers and timing that work.

Segmentation

Segments can be built from shopping behaviour, campaign engagement and customer details, and the app says free plan users can describe a segment in words and have it built for them. Klaviyo goes further here, with more data points and predictive measures, which matters once a list is large enough to split finely.

SMS and web push

SMS sits alongside email in the same workflows. Under UK rules, marketing texts need clear prior consent and an easy opt out in every message; our SMS marketing guide explains the rules and where texts earn their cost. Web push is unlimited on the paid plans, a useful extra channel at no added cost.

Omnisend vs Klaviyo

Omnisend and Klaviyo both do the core jobs well. The differences are in depth, data and price.

The flow trigger point matters more than it looks. When we moved five clients from Mailchimp to Klaviyo, the feature they valued most was building complex flows from the large range of triggers available through integrations with their store and apps. Subscription brands, stores with loyalty and review apps, and brands with several customer types tend to need that depth.

Cost is the other side. Some of our clients pay over £800 a month for Klaviyo alone, and list hygiene makes a real difference: removing 5,000 unengaged profiles from a 45,000 profile list cut one client's Klaviyo bill to £600 a month with no drop in email revenue. Before switching platforms to save money, clean the list you have. Our Mailchimp alternatives guide compares more options.

Who Omnisend Suits

Omnisend is a good fit for:

• Newer stores with lists under a few thousand contacts that want the core ecommerce flows at a low cost.
• Store owners running email themselves who value quick setup and ready made templates.
• Brands that want email, SMS and web push in one place without paying for advanced data features.

That matches what our own Omnisend clients tell us. Three of the stores we work with use it, and they say it is more cost effective, great for small to medium brands because setup is fast, and allows multichannel marketing on a budget.

Klaviyo is usually the better fit for:

• Stores with large lists that need fine segmentation and predictive measures such as expected next order.
• Subscription brands, which need flows triggered by subscription events; see our guide to Klaviyo flows for subscription brands.
• Brands whose email drives a large share of revenue, where the extra depth pays for itself.

How to Switch Email Platforms Safely

Moving between Omnisend, Klaviyo or any other platform carries one real risk: damaging deliverability. Follow these steps:

1. Export contacts with their consent status. Never import unsubscribed or suppressed contacts as subscribed.
2. Authenticate your sending domain on the new platform, with SPF, DKIM and DMARC records in place.
3. Rebuild forms and flows first, starting with welcome and abandoned cart, so revenue flows are never off.
4. Warm up sending. Start with your most engaged subscribers and widen the audience over two to four weeks.
5. Run both platforms briefly in parallel, then switch off the old forms and flows on the same day.

Our guide to stopping Shopify emails landing in spam covers domain authentication in detail.

Why Matters Perspective

We are a Klaviyo partner, so we have an interest to declare, and most of the stores we look after use Klaviyo. That said, Omnisend is a capable platform. For a small store with a simple customer journey it can do the job for less. The platform matters less than the flows: a well built welcome series and abandoned cart flow on Omnisend will outperform a neglected Klaviyo account every time.

Where we recommend Klaviyo is when a store needs deeper data and more flow triggers, as the five clients we moved from Mailchimp found. We are a Shopify Select partner with Verified Skills across development and marketing, our pricing is published, and retainer clients are billed one month in arrears with no long contracts.

Frequently Asked Questions

What is Omnisend?

Omnisend is an email and SMS marketing platform built for online stores. It connects to Shopify, collects subscribers with forms and pop ups, and sends campaigns and automated flows such as welcome, abandoned cart and post purchase messages, with web push notifications included.

How much does Omnisend cost?

Omnisend prices in US dollars by the number of contacts. Its pricing page lists Standard from $16 a month for 500 contacts and Pro from $59 a month for 2,500 contacts, with 30% off if you pay three months upfront. Prices rise with your list size, and SMS is charged per message on top.

Is Omnisend free?

Omnisend has a free plan for up to 250 contacts and 500 emails a month. Omnisend says it includes the same features as the paid plans, so it is a fair way to try the platform, but most growing stores outgrow those limits within months.

Is Omnisend better than Klaviyo?

Omnisend is usually cheaper and simpler for smaller stores, and its pricing is easy to follow. Klaviyo offers deeper segmentation, richer customer data and more ways to trigger flows from your store and apps, which is why most of our clients use it. Three of our current clients use Omnisend instead; they say it is more cost effective and quick to set up. The right choice depends on list size, budget and how advanced your email needs to be.

Does Omnisend work with Shopify?

Yes. Omnisend has a Shopify app that syncs customers, orders and products, so you can build abandoned cart, browse abandonment and post purchase flows from store data. The app also lists Shopify Flow as a supported integration.

Does Omnisend send SMS in the UK?

Yes. SMS is sold per message, and Omnisend says the price varies by country and volume, so check the UK rate on its pricing page. Under UK rules you need clear consent before sending marketing texts, and every message needs a simple way to opt out.

Can I move from Omnisend to Klaviyo?

Yes. Export your contacts with their consent status, rebuild your forms, flows and templates in Klaviyo, warm up sending gradually, and run both platforms in parallel for a short time before you switch Omnisend off. Never import unsubscribed contacts as subscribed.

Final Thoughts

Omnisend gives Shopify stores the essential email, SMS and push tools at a price that is easy to understand, and for many smaller stores that is exactly what is needed. As a list grows and the customer journey gets more complex, Klaviyo's depth usually becomes worth its higher cost.

Whichever you choose, build the welcome and abandoned cart flows first, keep the list clean, and protect your sender reputation when you switch. If you would like help deciding, email us.
