I just spent hours setting up all automations, flows, and logic only to find out that Omnisend forms don’t embed and popups won’t show at all on my site. I contacted support and spoke with Irem, and honestly, this was the worst support experience I’ve had on Shopify in years. They: blamed the Horizon theme (false) claimed custom HTML can’t be injected (also false) said they “checked the code” and found nothing (despite screenshots and the code being there) offered zero actual debugging or solution passed responsibility back to me instead of fixing their broken app Every excuse, no ownership, no fix, just deflection. I’ve worked with dozens of Shopify apps. When something breaks, good teams help you solve it. This team just tried to make it not their problem. At this point it’s clear: they want the subscription, not the responsibility. Extremely disappointed. Hours wasted. And absolutely unacceptable support for a paid app.

i just wanted the plan you can see here on the app store, $16 / month - EVERYTHING in Free plan, plus: 6,000 emails/month instead, after installing the up. this plan dosen't exist, and they wanted to charge me 600$ / month!!! that is crazy

I spended so much time trying to configure this app. First - I was not able to validate my domain because the same validation method was used by track123. Second - Strange pricing policy, where I should pay for total amount of customers, not for actual amount of sent email. Third - MY FAILED DELIVERY RATE 30%! I never had any issues not with YOTPO not with Shopify Flow. Customer support ask me to speak with Shopify.

WROST EXPERIENCE EVER! STAY AWAY FROM THIS SERVICE. PLEASE NOTE ONCE YOU PAY YOU CANNOT REFUND YOUR MONEY!

BIG MISTAKE Worst onboarding experience ever. I had to chase them so many times. They have layers for support that is dysfunctional. I was happy with Yotpo but they stopped SMS and they recommended to move these guys. Unfortunately waste of time and loss of potential revenue.

Really dissapointed, we are trying to setup and make test, but everything is buggy, and the customer support has zero knowledge how to support un, really unhappy with the experience.

Very disappointed and feels scammy. After deleting the app, the monthly sms subscription is still active, so be sure to go to your store settings and cancel that subscription. I learned this the hard way and support was not helpful.

If I could give them no stars I would. Was charged for 3 months on November 5th, 2025, come December 3rd--I cannot send any emails due to an undisclosed error (saving failed, try again). Contacted Omnisend and was gaslit that it was somehow my fault even with trying on two different laptops, three different browsers, and two mobile phones that were not connected to the same wifi network. Support refuses to refund me even though their policy states they will "consider a refund" under specific circumstances: "A customer cannot use the features over the period they have paid for due to a system malfunction and unexpected issues caused by it.". I paid for three months and used less than one. I'm still being charged for the other two months even with uninstalling and closing my account with this company due to this negligent behavior on their part. Don't be me, find a better company to use to manage your email list!

Misleading information to get you upgrading to pro plan! Upon signing up, I was shown the information on their website that I would be getting 6,090 monthly sms with the pro plan. So I signed up to the pro plan (which I also took a screenshot of this information shown on my computer and have proof of this). I, then, sent my first sms campaign to 1,161 contacts and their website showed that my sms credit was already almost used up! I contacted support and was told that the original message with 6,090 monthly sms shown to me was just an estimate though this *estimate* part was never shown or included in their information when I signed up. I'm truly disappointed and feel like I was scammed to use their pro plan.

What a joke.. On the shopify site it says pricing is $16 for the Pro version, however when you click on the more details it jumps to $59. However when you start going through the process of signing up, they have the price at $145. TALK ABOUT BAIT AND SWITCH

This is the worst app I've ever seen—they banned my account for no reason whatsoever. If I could, I wouldn't give them even one star.

Precisei utilizar envio de SMS para divulgar uma campanha que tinha data e hora certa para iniciar, fiz um teste na sexta-feira e verifiquei que as mensagens não estavam chegando, entrei em contato com o suporte que me informou que me retornariam em 72h, avisei que precisava solucionar antes de segunda-feira. Ninguém me retornou e hoje quando questionei me deram um retorno dizendo que não consegui enviar por conta de um link, o que não é verdade visto que fiz o teste de diversas formas inclusive sem link nenhum e a mensagem simplesmente não chega. Estou profundamente insatisfeita com a ferramenta e com o suporte fornecido.

Very frustrating and unfortunate cant get issue resolved

This terrible app and company. I signed up, paid money which will be over $500. My account was hacked and large amount of emails were added to customer list. Spam email went out to over 30,0000 people from my company email. How did it happen?! This can potentially ruin my company! I cancelled my account immediately and wrote support. The security of their customer's is not top priority. I cannot believe this happened. I will be emailing Shopify to report this

I wanted to move away from Shopify’s built-in emails and had high hopes for this app. I spent hours setting up templates only to find they were very basic and not much different from Shopify’s. There was also an issue with the review request template, which I had integrated with Stamped reviews. Then I was told they were removing the review request feature entirely, saying they don’t see the value in asking customers for reviews. That’s a crucial part of running an online store. Honestly, the whole experience was confusing and disappointing.

Horrible. Doesn't work properly. Customer service is laughable.

After much research I decided to move my email marketing, after 7 years with Mailchimp, to Omnisend. It promised so much, especially it's strong integration and powerful tools for Shopify. THIS PLATFORM DOES NOT FULLY INTEGRATE WITH SHOPIFY. I spent DAYS and DAYS and DAYS creating all my automated flows, only to realise that Omnisend hadn't sync'd my customer order data fully. I have customers who have ordered 22 times in Shopify, only showing 3 in Omnisend, I have customers who have ordered 15 times in Shopify only showing 1 in Omnisend - every customer I have looked into does not show the correct order number, so this means ALL my segments and triggers DO NOT WORK correctly. I have spent HOURS and HOURS and HOURS on the Omnisend live chat, i've spoken to 6 or 7 different people, who all took my on a wild goose chase making changes to my segment and email triggers, even though I mentioned several times that I didn't see what difference this would make if the actual order data wasn't correct. I was dismissed, and as they are 'experts' went along with all the changes they progressively asked me to make, and guess what, NONE OF IT WORKED because the customer order data isn't correct!!! It's been passed to technical teams, developers, etc and still it's not correct. I've paid for my membership for 3 months upfront (as a small business this is a lot!), I emailed them separately begging for help over a week ago and have had no reply, and now my live chat contact has gone quiet. I'm behind in all areas of my business as this has taken up so much of my time - JUST AVOID.

If anything happens in life that takes you away from your store and omnisend for more than 6 months, they delete everything. Every campaign along with every email you've acquired. I used omnisend for about 9 years and loved it until life got in the way and they deleted all of my hard work and contacts. I do not recommend using their marketing services.

Abusive Account Suspension & Stolen Credit – Avoid at All Costs I topped up my Omnisend account with $400 solely to use their SMS order confirmation feature. After using only $200, they suspended my account without warning or justification and now refuse to refund the remaining $200. This is not just unprofessional – it’s outright theft. No response, no transparency, no accountability. I trusted this app because it was listed in the Shopify ecosystem, but clearly, Omnisend operates with zero integrity. Shopify should take action against this kind of abuse. Stay away – there are far better and more ethical alternatives.
