TL;DR: Omnisend is an email and SMS marketing platform built specifically for online stores. It plugs deep into Shopify and the other big ecommerce platforms, and it gives smaller brands most of what Klaviyo does at a lower price. Ease of use and the ecommerce automations are the real draw. SMS costs and a recent change to how SMS is sold are where you need to do the maths. Our rating: 4.4 / 5.

How we assessed Omnisend
Quick word on method first, because a lot of email-tool reviews are written by people who earn a commission on a rival platform, which makes the verdict about as neutral as a fox grading the henhouse.
We don’t sell email software. Rewardio is a cashback platform, so we earn the same whether you run Omnisend for years or drop it next week. That lets us call it straight. This review leans on a few things here: the published feature set, the public review profiles, and what real store owners keep reporting. Where the picture is mixed, and on pricing it can be, we say so.
That’s less glamorous than claiming we ran our own store on it for a year. It’s also more honest than most of page one.
What is Omnisend?
Omnisend is an email and SMS marketing platform made specifically for ecommerce. It started life in Lithuania in 2014 as a tool called Soundest, founded by Rytis Lauris and Justas Kriukas. It took the Omnisend name in 2017 as it grew beyond email into SMS and more. Today it’s used by more than 150,000 online stores.
The pitch is simple. Instead of paying for separate tools to send email, run SMS and fire automated flows, you do it all in one platform that’s actually built for selling online. It connects natively to Shopify, WooCommerce and BigCommerce, among other platforms. The Shopify integration in particular is among the deepest you’ll find at this price.
Put simply, Omnisend is the email and SMS engine for an online store, with the ecommerce wiring built in rather than bolted on.
The tools, explained plainly
Here’s what you actually get, without the sales gloss.
- Email campaigns. The core is a drag-and-drop email builder with ecommerce-ready templates. You can pull products straight from your store catalogue into a campaign, which saves a lot of fiddling. Reviewers consistently call the builder one of the easiest to pick up.
- Other channels. Omnisend also runs SMS text campaigns and web push notifications from the same place as email. A single automated flow can reach someone across more than one channel. SMS is billed separately from your plan, and we’ll come back to that under pricing.
- Automation. This is where Omnisend earns its keep. It ships with a stack of pre-built ecommerce automations that actually drive revenue. Think abandoned cart, browse abandonment and post-purchase follow-ups. You switch them on, tweak the messaging, and they run in the background.
- List growth. Signup forms, popups and landing pages help you grow the list in the first place. They’re easy to build and tie straight into your automations.
- Targeting. You can slice your audience by behaviour and shopping history, then send revenue reports that show which campaigns actually made money. Segments can also sync into Google and Meta ad audiences, which keeps paid targeting current.
The honest read: Omnisend covers the whole ecommerce marketing job in one place. It does the everyday work, campaigns, automations and list growth, without turning you into a specialist. The depth is in the ecommerce features rather than in heavy, enterprise-grade analytics.

Where Omnisend is strongest
The clearest strength is ecommerce focus. This isn’t a general newsletter tool with a store plugin tacked on. The product picker, the behaviour triggers and the revenue reporting are all built around selling. The features line up with what an online store actually needs.
The second strength is value. Store owners repeatedly describe Omnisend as most of what Klaviyo does for a good deal less, especially on smaller lists. The free plan is genuinely usable too, not a thinly disguised trial, which makes it easy to start.
The third is ease of use. Across G2, Capterra and the Shopify App Store, the single most common word in the reviews is some version of easy. For a small team without a dedicated email specialist, that matters.

The biggest criticism, head-on
The honest knock on Omnisend is cost, and specifically SMS. The plan prices are fair, but SMS is billed on top, and for a brand that leans on text it adds up fast. Several reviewers say the same thing, that SMS worked out pricier than they expected next to a rival like Klaviyo.
There’s a recent wrinkle worth knowing. From May 2026, new customers can only send SMS on the Pro plan, with usage-based pricing rather than included credits. If SMS is core to your plan, factor that in before you choose a tier.
The other common gripe is creative control. The template editor is easy but not endlessly flexible, you usually start from a template rather than a blank canvas, and a few users want deeper customisation. Analytics also trail Klaviyo’s once you get into serious attribution. None of this is a deal-breaker for most stores, but it’s worth weighing if you’re a power user.
Pricing and value
Omnisend pricing runs on a contact-based model, so the more contacts you store, the more you pay. There are three main tiers plus a custom option.
The Free plan costs nothing and covers up to 250 contacts and 500 emails a month, with access to most features. Standard starts at about $16 a month and scales with your list size, running into the low hundreds as you grow past several thousand contacts. Pro starts at about $59 a month, adds unlimited email sending, and includes SMS credits for customers on the older model. A custom Enterprise tier sits above that.
Two things shape the real cost. SMS is a separate, usage-based charge on top of your plan, and on heavy sending it can rival the plan fee itself. And billable contacts can include people who aren’t active subscribers, so the count creeps up as you automate more.
On value, the read is straightforward. For most Shopify and WooCommerce stores without heavy enterprise needs, Omnisend gives you the bulk of what the premium tools do for less. Paying three months upfront knocks roughly 30% off, and signing up through Rewardio adds 10% recurring cashback on top, paid every billing cycle. We break down the tiers and the cheapest route to buy in our companion Omnisend pricing guide.

Support and ease of use
Ease of use is Omnisend’s calling card. The dashboard is clean and campaigns are quick to build. Automations are just as fast to set up. Most people are productive without training, and that’s the single most praised thing in the reviews.
Support gets good marks too. Omnisend offers 24/7 email and chat support across plans, and reviewers generally find it responsive. For a tool aimed at busy store owners, that reliability counts.
What real users say
You don’t have to take our word for it. The public feedback is consistent and, by software standards, very warm.
On the Shopify App Store, Omnisend holds about 4.8 out of 5 from more than 2,900 reviews. On G2 it sits near 4.6 from over 1,100 reviews, and on Capterra it’s around 4.7 from more than 800. A few themes repeat:
- Ease of use wins the most praise. Store owners single out the drag-and-drop builder and how quickly they get a campaign or automation live.
- The Shopify integration gets a lot of love. Merchants like that products, behaviour and orders flow into Omnisend without manual work.
- Value comes up again and again. The recurring line is strong ecommerce features at a friendlier price than the premium alternatives.

Two honest caveats. The warm averages sit alongside specific gripes about SMS cost and template flexibility, so read recent reviews with your own use in mind. And glowing affiliate write-ups are everywhere for tools like this, ours included, so the verified user reviews carry more weight than any single blog verdict.
Is Omnisend safe and legitimate?
Yes. Omnisend is a well-established platform that’s been running since 2014 and is used by more than 150,000 stores, so this isn’t an unknown quantity. It’s a mainstream choice for ecommerce email and SMS. The security and data-handling are what you’d expect from a platform at this scale. As with any tool that holds customer data, check that its terms fit your own privacy and compliance needs, but the platform itself is entirely legitimate.
Pros and cons
What we liked:
- Built specifically for ecommerce, with deep Shopify and WooCommerce integration.
- A beginner-friendly builder for email, SMS and automations.
- Strong pre-built ecommerce automations that drive revenue out of the box.
- A genuinely usable free plan, not just a trial.
- Excellent value against premium tools like Klaviyo, especially on smaller lists.
What gave us pause:
- SMS is billed separately and can get expensive on heavy sending.
- From May 2026, new customers can only use SMS on the Pro plan.
- Template and customisation options are easier than they are flexible.
- Analytics and attribution trail Klaviyo for advanced users.
- Contact-based pricing can creep up as your list and automations grow.
Who should buy Omnisend, and who shouldn’t
Omnisend is an easy recommendation if you run a Shopify or WooCommerce store. You get one tool for email, SMS and automation without paying enterprise prices. It suits small and mid-sized brands especially, and the free plan makes it painless to try before you commit.
Look elsewhere if you’re an enterprise team that needs the deepest segmentation and custom attribution, where Klaviyo still has the edge. And if SMS is the heart of your strategy, price the new usage-based model carefully, because it can shift the maths against you.
Frequently asked questions
What is Omnisend? Omnisend is an email and SMS marketing platform built specifically for ecommerce. It connects to Shopify, WooCommerce and other store platforms. From there it handles campaigns, automations and list growth in one place. It’s aimed at online stores that want ecommerce-ready marketing without stitching several tools together.
Is Omnisend free? There’s a free plan that covers up to 250 contacts and 500 emails a month, with access to most features. It’s genuinely usable for a small store or for testing. Beyond that, you move to the paid Standard or Pro plans as your list grows.
How much does Omnisend cost? Pricing is contact-based. The Standard plan starts at about $16 a month and rises with your list size. The Pro plan starts at about $59 a month and adds unlimited email plus SMS credits on the older model. SMS is charged separately on top, so model your text volume before choosing.
Is Omnisend better than Klaviyo? It depends on your stage. Klaviyo has deeper segmentation and attribution. It tends to suit larger, more advanced teams. Omnisend gives most of that core ecommerce functionality at a lower price, with a simpler setup. For Shopify and WooCommerce stores that aren’t enterprise-scale, Omnisend usually wins on value.
Does Omnisend do SMS? Yes, alongside email and web push. One important change: from May 2026, new customers can only send SMS on the Pro plan, with usage-based pricing. SMS is billed separately from your plan, so it’s worth estimating volume before you pick a tier.
Can I get cashback on Omnisend? Yes. Through Rewardio you get 10% recurring cashback on Omnisend, paid every billing cycle for as long as your subscription stays active. Cashback tracks on paid plans, so the free plan alone doesn’t qualify. Check the merchant page for the live rate.
The final verdict
Omnisend knows exactly who it’s for. It’s an ecommerce-first email and SMS platform. It hands smaller and mid-sized stores most of what the premium tools do, for less. The learning curve is gentler too. The deep store integrations, the pre-built automations and the genuinely usable free plan are the reasons to choose it.
It won’t be the pick for an enterprise team that needs the most advanced analytics, and the SMS pricing deserves a careful look before you commit. For its core audience of growing online stores, though, the value is hard to argue with.
Our rating is 4.4 out of 5. Apply cashback through Rewardio and the value case gets stronger still.
Transparency note: This review draws on Omnisend’s published feature set, the public review profiles, and recurring themes in real user feedback, not a paid test account. Where the picture is mixed, we’ve said so. Rewardio earns cashback commission when readers buy through our links. That doesn’t change our verdict, and we flag the product’s limits openly above.
