TL;DR, Should you still use Omnisend in 2026?

Omnisend is the friendliest ecommerce email platform we have measured, and its own users make the comparison for us. “More streamlined and intuitive than Klaviyo,” writes one reviewer, unprompted, in a Capterra Pros field. Capterra scores ease of use at 4.6 and customer service at 4.6, and support praise is the most consistent theme in the corpus: “customer support is immaculate,” “off the charts helpful,” “great account managers.”

Then there is the number that changes the recommendation. The independent inbox-placement panel puts Omnisend at 75.1 percent in its most recent published round. That is the lowest figure we have published for any platform on this site, against 94.2 for ActiveCampaign and 89.5 for Mailchimp. Roughly one email in four did not reach an inbox.

And the history is volatile rather than steadily poor. Across rounds the same panel recorded 85.1, 85.3, 67.6, 72.5, 87.9 and 75.1 percent. A twenty-point swing between rounds is a different kind of risk from a consistently mediocre score: you cannot plan against it.

Our take Omnisend earns 7.1/10. It is a genuinely nicer tool than Klaviyo to live in, at a friendlier price, with better support. It is also the only platform on this site where we would tell you to run your own inbox-placement test before you migrate, and to keep running it.

The context you need before evaluating Omnisend in 2026

Omnisend started in 2014 as Soundest, a Lithuanian email tool for online stores, and took its current name on 31 October 2017 once SMS and web push were added. The company has never been acquired and is still run by co-founder Rytis Lauris. In a category where Klaviyo is publicly listed, Constant Contact is private-equity owned and MailerLite belongs to a Warsaw-listed group, founder-run independence is itself a differentiator.

The structural fact to understand before you compare pricing is how contacts are counted. Billing counts every contact you are allowed to message, abandoned-cart visitors included, not only subscribers. That puts Omnisend on the same side of the line as Klaviyo rather than Brevo, which meters emails sent. A Shopify store accumulates contactable people from checkout events it never intends to mail, and they are in the count.

The second is what Omnisend does to your store’s own emails. It replaces Shopify’s native order and shipping notifications with its own workflows, which is the appeal for merchants who want a consistent brand across transactional and marketing. But only Shopify Plus merchants can switch the native confirmation email off entirely. Everyone else runs both, which means customers can receive two confirmations. That is not in any feature comparison and it is exactly the kind of detail that surfaces after migration.

Third, and it bears on everything below: there is no SMTP relay and no transactional send endpoint. One reviewer names it directly in a Cons field: “Lack of SMTP support. Not a dealbreaker, but.” The order notifications run through Omnisend’s own workflow engine, not through a relay you can point an application at.

Finally, a pricing detail worth checking before you sign. The figure shown on the pricing page is a first-upgrade introductory price for three months. The Standard plan settles at $16/mo. Model the fourth month, not the first. Our pricing tab has the ladder.

What Omnisend does well

Its users compare it to Klaviyo and prefer it, in their own words

Ease of use is the dominant praise theme across all five pages we read, and Capterra scores it 4.6 against Klaviyo’s 4.5. What makes it more than a sub-score is that reviewers reach for the comparison themselves: “more streamlined and intuitive than Klaviyo,” “how user friendly it is compared to other,” “its very much easy to use compared to.” Nobody prompted them. When a smaller competitor’s users spontaneously name the market leader as the thing they escaped, that is a real product quality.

Support is the most consistently praised thing in the corpus

Capterra scores customer service at 4.6, equal to its ease score, which is unusual. The language is unusually strong even by review standards: “customer support is immaculate,” “the customer service is off the charts helpful,” “they have great account managers,” “great and readily available support 24/7.” Several mention a named customer success manager, which points to real account coverage rather than a ticket queue. For a platform at this price, that is genuinely unusual.

Email, SMS and web push really do live in one workflow

This is what the name is for, and it is not a bolt-on. Reviewers build a single automation that reaches across channels: “campagnes email + SMS + push au même” endroit, “the combine powerful features,” “a robust email and SMS marketing” platform. Free SMS credits appear repeatedly in Pros fields. For a store that wants an abandoned-cart sequence to escalate from email to text, this is one tool instead of two integrations.

The Shopify fit is deep, and around 280 integrations sit behind it

“Works well with our Shopify website,” “data sync with Shopify,” “easy to set up and intergration with shopify” recur throughout the corpus. Omnisend is built for the store rather than adapted to it, and it goes further than most by taking over order and shipping notifications rather than sitting alongside them.

It ships an official MCP server, which most of its size class does not

Among the platforms we have profiled, only Omnisend, Klaviyo, Brevo, ActiveCampaign and Flodesk ship official agent tooling. Mailchimp and Constant Contact, both far larger, ship none. For a founder-run company of this size to be ahead of them on this axis is worth noting.

Where Omnisend falls short

The measured inbox placement is the lowest on this site, and it swings

This is the finding, and it outweighs everything above for some buyers. EmailToolTester‘s most recent published round puts Omnisend at 75.1 percent. Here is the panel in context:

PlatformMost recent published round
ActiveCampaign94.2 percent
Constant Contact91.7 percent
GetResponse90.9 percent
MailerLite89.8 percent
Mailchimp89.5 percent
Brevo88.3 percent
Omnisend75.1 percent

The gap to the next platform is 13 points. And the round history is the part that should worry an operator more than the headline: 85.1, 85.3, 67.6, 72.5, 87.9, 75.1. That is a twenty-point spread. A platform that consistently delivers 85 percent is a platform you can plan a revenue forecast against. A platform that delivers between 68 and 88 depending on the quarter is not.

Two things we will not do with this number. We will not claim your list will see 75.1 percent, because a panel test uses a seed list and yours is not it. And we will not quietly average the rounds into a friendlier figure, because the variance is the finding. What we will say is that this is the one platform in our set where an independent placement test of your own is not optional, and the corpus offers no comfort either way: reviewers rarely mention deliverability, in either direction.

The review corpus arrives in bursts, which is why the 4.7 needs reading carefully

We noticed this while dating the reviews and it changes how much weight the headline score can carry. Of the 125 rows we read, roughly 76 are dated within October 2024, and a further 18 share a single date, 10 April 2025. Eighteen reviews on one day is not an arrival pattern, it is a campaign.

This is not an accusation of anything improper; soliciting reviews is normal and Capterra verifies them. But it has two consequences a reader should know. First, the corpus is 2024-vintage on a product that has changed since, so it tells you less about Omnisend today than a steadily-arriving corpus would. Second, reviews gathered by campaign skew positive, because the people who answer a prompt are the people still using the product. Read the 4.7 as a well-run solicitation, not as a continuous temperature reading.

Non-Plus Shopify merchants can end up sending two confirmations

Omnisend replaces Shopify’s order and shipping notifications with its own, but only Shopify Plus merchants can switch the native confirmation off entirely. On any other Shopify plan, both fire. Your customer gets the Omnisend-branded confirmation you designed and Shopify’s default one underneath it. That is a migration surprise rather than a hidden fee, and it is worth checking your plan tier before you build the workflow.

The complaint that repeats most is about integrations that are missing

Across all five pages, the single most repeated criticism is a gap in the integration catalogue: “lack of some integrations,” “missing some features and integrations,” “limited integrations with tools such as Yotpo,” “it cannot integrate,” “the integration with prestashop isn’t the best yet,” “challenges with integrating with Elementor.” Around 280 connectors is a respectable catalogue, but it is a third of ActiveCampaign’s thousand, and reviewers keep finding the edge of it.

Templates and design customisation stop earlier than reviewers want

A steady second cluster: “wish there where more premade templates,” “limited product layout templates,” “customization is quite limited, cannot highlight one part,” “I cannot customize that much on the designs,” “for advanced users accustomed to creating custom HTML.” The editor is easy, which is the trade: it is easy because it does not let you do very much. If your brand needs art direction, Flodesk is the other end of that trade.

SMS is the upsell, and reviewers price it as one

Free SMS credits appear in Pros fields, and the cost of SMS at volume appears in Cons fields: “the SMS cost: SMS marketing is an excellent” channel but, “the SMS package is costly,” “have to purchase additional credits to send SMS.” The omnichannel promise is real and the omnichannel bill is separate from the plan. Budget SMS as a line item, not as an included feature.

Account risk: not rated

Ban tolerance: not rated Our rule is that this field comes from a published acceptable-use or prohibited-industries policy, or it stays empty. We did not source one at the level Flodesk publishes, so the field is unset rather than guessed.

The corpus offers no signal either. Unlike Brevo, where 17 of 157 reviewers described suspension or abrupt verification, account termination does not appear as a theme here at all. That is an absence of evidence, not evidence of a permissive policy.

What real users actually say

We read 5 pages of Capterra reviews, 125 rendered rows, and deduplicated on the exact record, leaving roughly 115 distinct. As explained above, the dating is heavily clustered, so treat this as a snapshot of two moments rather than a running average.

How we count Capterra truncates the Pros and Cons fields, so a theme raised after the cut is invisible to us. Every figure is at least N of the rendered excerpts, never a count of whole reviews. A substantial share of the Cons fields contain no criticism at all, so complaint shares are smaller than they look against a corrected denominator.

Praised most often

  • Ease of use – the dominant theme on every page, often stated as a comparison against Klaviyo
  • Customer support, sometimes named individually – the second-largest cluster, Capterra sub-score 4.6
  • Shopify integration and data sync
  • Email, SMS and push in one workflow, with free SMS credits
  • Price and value, especially against Klaviyo

Complained about most often

  • Integrations missing or incomplete – the single most repeated criticism
  • Templates and design customisation limited
  • Cost as the contact list grows, and SMS priced separately
  • Analytics and reporting depth
  • Bugs in the editor and scheduled sends
  • No SMTP support – named directly in a Cons field

The mixed cluster is simplicity itself, and it is the honest heart of this product. The most praised thing and several of the most criticised things are the same design decision. Reviewers love that the editor is uncomplicated. Reviewers also say “customization is quite limited” and “for advanced users accustomed to creating custom HTML” it falls short. Omnisend is easy because it is narrow. If you have arrived here from Klaviyo because Klaviyo was too much, that trade is exactly what you wanted. If you arrive from a design-led tool, it is exactly what you will resent.

The second cluster is price. Reviewers call it “the most value for money product” and “super simple to use and very well priced,” and also “a bit expensive for my small” store and “pricing can escalate with larger contact lists.” The split maps onto store size and, more precisely, onto how many contactable people the store has accumulated, since those are what is being counted.

What is conspicuously absent is deliverability, in either direction. Almost nobody praises it and almost nobody complains about it. Set against the 75.1 percent panel figure, that silence is worth naming: most senders do not know their placement rate, because a message that lands in spam produces no complaint, no bounce and no signal in a review field. It just quietly does not work.

How we score The mean here is (8.5 + 7.0 + 5.0 + 8.5 + 6.5 + 7.0) / 6 = 42.5 / 6 = 7.1. Two fixed anchors hold the scale still: Mailchimp at 6.3 and Postmark at 7.8. Omnisend carries our highest joint scores for ease and support and our lowest deliverability score on the site. A tool people love using, whose mail arrives least reliably, nets out near the middle. If placement is not a constraint for you, the 7.1 understates it. If it is, the 7.1 overstates it.

Who should still use Omnisend

Recommended if

1. Klaviyo was too much tool for your store

This is the case Omnisend was built to win and its users describe it in exactly those words. Capterra ease of use 4.6 against Klaviyo’s 4.5, a friendlier price, and support that reviewers call “immaculate.” If nobody in your store will spend two weeks learning a platform, this is the ecommerce answer.

2. You want email, SMS and push in the same automation

Not three tools stitched together. One workflow that escalates an abandoned cart from email to text, with free SMS credits to start. Budget SMS separately at volume, but the cross-channel design is genuine and it is what the name is for.

3. Support quality matters more to you than feature ceilings

Capterra customer service 4.6, equal to its ease score, with reviewers naming individual account managers. For a small store without a marketing hire, having someone answer is often worth more than a feature you would not have used.

Who should look elsewhere

1. Your revenue depends on the email arriving

75.1 percent in the most recent independent round, 13 points behind the next platform, with a twenty-point spread across rounds. If a missed send is a missed sale, ActiveCampaign at 94.2 or Constant Contact at 91.7 are the measured alternatives.

2. You need real automation depth or revenue attribution

Reviewers say it plainly: “Omnisend lacks some advanced or situational features that you need.” Klaviyo is the tool if segmentation on behaviour and attribution per flow is the requirement, and we rate its automation 9.5 against Omnisend’s 7.0.

3. You are on Shopify but not on Shopify Plus, and you want native confirmations off

Only Plus merchants can disable Shopify’s own confirmation email entirely. On any other plan you run both, and customers can receive two. Check your tier before you build the workflow.

4. Anything in your stack needs to send an email

No SMTP relay and no transactional send endpoint. A reviewer names the gap directly. For application mail, Postmark from $15/mo, or Brevo if you want marketing and transactional on one account.

5. Your programme is MLM, crypto, gambling or political

The AUP of April 30, 2026 forbids multi-level marketing and pyramid schemes, unregulated cryptocurrency schemes, gambling and casino services, predatory lending and high-interest loans, and political campaigning and fundraising. Omnisend reserves the right to act “without prior notice or liability,” may give a warning but is not obliged to, and states that queued messages may simply never be delivered. The list is public and was refreshed this year.

The gap is 0.1, far under the 1.5 point threshold at which we stop to reconcile a divergence. On the public panels Omnisend scores as well as anything in this category.

Which is exactly why this profile needs the deliverability section. A 4.7 star rating and a 75.1 percent placement rate are not in contradiction, and understanding why is the most useful thing on this page. Review scores measure the experience of using software: the editor, the support, the price. Inbox placement measures something the sender cannot see. An email that lands in spam generates no bounce, no complaint and no support ticket. The merchant sees a campaign marked sent and a soft week of revenue, and rates the platform five stars for being pleasant to use. Both readings are honest. Only one of them is about whether the mail arrived.

Top 3 alternatives

  • Klaviyo is the comparison every Omnisend prospect runs, at 260 searches a month for omnisend vs klaviyo. Klaviyo is deeper, harder and considerably more expensive. We rate it 7.3 against Omnisend’s 7.1, and the gap is smaller than the price difference suggests.
  • Brevo is the answer if the contact-counting model is what bothers you. Brevo meters emails sent rather than contactable people, includes SMTP, and we rate it 7.7, the highest marketing platform on this site.
  • MailerLite is the answer for a store that is really a newsletter with a checkout attached. Cheaper, simpler, and with a measured placement rate 15 points higher.

Frequently asked questions

How much does Omnisend cost? There is a free tier at 250 sendable contacts and 500 emails a month, then Standard from $16/mo. Two things to check: the lower figure shown on the pricing page is a three-month introductory rate on your first upgrade, and billing counts every contactable person including abandoned-cart visitors, not only subscribers. Full ladder on our pricing tab.

Is Omnisend free? There is a permanent free tier: 250 sendable contacts and 500 emails a month, with the automation and workflow features included. It is small but not crippled, and it is enough to build a real abandoned-cart flow and watch it fire before paying.

Omnisend vs Klaviyo: which should a store pick? Klaviyo if segmentation depth and revenue attribution are the point and someone will own the tool. Omnisend if you want most of the outcome with far less friction: its own users write “more streamlined and intuitive than Klaviyo” in their reviews. Our scores are close, 7.1 against 7.3, and they diverge on different axes: Klaviyo wins automation 9.5 to 7.0, Omnisend wins ease 8.5 to 6.5.

Omnisend vs Mailchimp? Omnisend for a store, Mailchimp for a newsletter. Omnisend’s ecommerce triggers, cross-channel workflows and Shopify sync are built for retail; Mailchimp treats ecommerce as an add-on. Mailchimp has the better measured inbox placement, 89.5 against 75.1. Our scores: Omnisend 7.1, Mailchimp 6.3.

Does Omnisend work with Shopify? Yes, and deeply: it replaces Shopify’s own order and shipping notifications with its own workflows. One caveat that catches people after migration: only Shopify Plus merchants can switch the native confirmation email off entirely. On other plans both fire and a customer can receive two confirmations.

What is Omnisend? A Lithuanian ecommerce marketing platform founded in 2014 as Soundest and renamed in October 2017. Founder-run and never acquired. It combines email, SMS and web push in single workflows and has no SMTP relay. Full background on the Omnisend hub.

What are the best Omnisend alternatives? Klaviyo for depth, Brevo for value and SMTP, MailerLite for simplicity. Full list on the alternatives tab.

Is Omnisend good? On the public panels, very: 4.7/5 on Capterra and 4.6/5 on G2. We rate it 7.1/10. The gap between those two judgements is the deliverability figure, which star ratings do not measure and senders cannot see.
