Klaviyo: Email Marketing & SMS

I have been using Klaviyo for a few years now, and using their Review app as well. About 3 months ago we found out that Klaviyo was inserting an extra script on our website causing it to be slower. For 3 months they didn't solve the issue, claimed we had hardcoded on our site and some other claims that had nothing to do with the issue. After pressuring the team to investigate this, it turned out their own Review app was causing the issue. Even when it is their own error they expect us to fix it and spend time on fixing it. We sent them an email nearly a week ago requesting them to fix the issue, no reply. Follow up email no reply! Third email, no reply. Never thought I would be giving Klaviyo such a bad review but it really shows the "respect" they have for their customers! Unbelivable disrespect to paying customers! But here you go Klaviyo, your behavior towards your customers is absolute shit! Could not be unhappier as a customer for several years! Please spare me with your standardized bullshit reply! You had days to get back to us, so a reply of a member will reach out to you is worthless!

It’s okay but when trying to cancel it makes it extremely hard. I deinstalled the app wanting to stop it, and got an email that it will automatically bill me due to maxing the amount of subscribers. Logging it to cancel the account it so challenging and I still don’t know if it’s cancelled properly.

One star. The software is fine. The company is the problem. I run a resale shop. Part of my inventory is published adult art books and Japanese gravure cards. Legal, sold openly on every major marketplace. I sent one campaign that featured an item in that category, not knowing it conflicted with their acceptable use policy. There was no warning. No takedown request. No do that again and we terminate. Compliance reviewed the account and ended it. The notice said that after a thorough review they would not be able to continue serving me. I was never asked to fix anything, because fixing it was never on the table. That is the part worth knowing before you build here. Most platforms flag you first. Klaviyo does not. One violation, even an honest one, and you are packing up. You get 30 days to leave and no refund on time you already paid for. I lost my flows, my templates, and my account access, and rebuilt my email setup elsewhere with no notice. If any part of your catalog sits near a line you have not read carefully, assume you get exactly one mistake.

removed klaviyo because too expensive. Removing it has damaged my code and now shopify team are having to work to fix the problems. Avoid klaviyo like the plague!

This is not a user friendly app... maybe all email apps are the same. However, the AI 'help' used by Klaviyo runs around in circles and is a step above useless.

Expensive and impossible to manage effectively.

its a scam and they put their ugly logo under the mail, ive ss of mails telling me ill be charged and i didnt even use this shitty app

The platform functionality might be powerful, but the user experience is incredibly frustrating. When encountering technical issues with dynamic variables in templates, there is absolutely no way to get basic support unless you upgrade to a paid plan. Worse, when trying to log into the Klaviyo Community to post a question, the website gets stuck in an infinite login redirect loop due to cross-domain cookie issues. As an e-commerce merchant, spending hours fighting broken authentication logic and paywalled support instead of resolving a simple issue is completely unacceptable. Highly disappointed with the customer experience.

I uninstalled it. A large number of bots from Miami are signing up and creating fake email addresses, and there’s no solution. I even suspect they’re doing this themselves to pressure you into upgrading your plan.

They make it impossible to clear all inactive profiles to susspended. This way they can keep increasing your monthy charge due to profiles. The app is also VERY HARD TO USE. We are an IT company and we find it backwards and HARD. FIND ANOTHER SOLUTION!!!!!! . Klaviyo is outdated and bad

Simply not working

Wir nutzen die App für E-Mail Marketing und das funktioniert auch sehr gut. Was mich aber stört ist die Preispolitik. Für ganz kleine und große Unternehmen sind die Preise in der Höhe nachvollziebar, aber gerade für Unternehmen die am Wachsen sind ist die App extrem teuer. In diesem mittleren Bereich steigen die Preise (Stückkosten) so extrem steil an, dass es wirklich nicht mehr schön ist. Ich finde die Strategie unfair, große Unternehmen zu belohnen und Unternehmen in der Wachstumsphase derart zu belasten. Für Interessierte empfehle ich unbedingt, die Preise genau durchzuspielen.

Unfortunately, we can’t recommend Klaviyo for several reasons. Basically, you constantly get the impression that their only goal is to push customers into a higher plan and keep them there. 1. Many fake profiles are created that inflate the plan count. 2. Deleting profiles is very cumbersome—you have to create a segment to do it. 3. Even then, the option to delete is still missing, and we can only suppress the profiles. If deletion is possible, the option is very well hidden. 4. Support isn’t helpful; they write long messages that don’t make sense and refer you to confusing FAQs. Or they end the conversation while you’re still in the middle of following their instructions. 5. Overall, we’ve tried multiple times over the past few months to resolve our issues across various stores, but we haven’t gotten anywhere. We’re still on a higher-tier plan and haven’t been able to delete any profiles.

i have already uninstalled the app, it is still charging my company card for service fee

Can literally never get Klaviyo to do what I need it to do. So disappointed to spend eleventy billion dollars a month on this. Just today, created a segment in Shopify to import to Klaviyo and it shows up in Klaviyo with ZERO people on it.

Nicht empfehlenswert. Kein Support, schlechtes Interface, grundlose Kündigungen.

0 stars, trying to disconnect and it won't let me

Klaviyo urgently needs to take inspiration from Canva because right now the editing experience feels outdated, clunky, and honestly exhausting.I’d honestly go as far as saying that Klaviyo is one of the worst apps I’ve ever used in my entire life when it comes to editing anything. The email marketing editor is unbelievably complicated for absolutely no reason. Nothing about it feels intuitive. Every simple task turns into a frustrating, time-consuming mess. It genuinely feels like the product was designed by engineers who never actually had to create a real marketing email themselves. The UX is terrible, the workflow is confusing, and basic editing actions feel painfully overengineered. Instead of helping you move fast, the platform constantly fights against you. What’s shocking is that email marketing should be simple in 2026. Apps like Canva proved years ago that powerful tools can also be clean, visual, and easy to use. I never write negative reviews about apps. In fact, this is probably the first time in my life I’ve felt the need to leave one. But the experience was genuinely that bad. For a platform this expensive and this popular, the editor is embarrassingly bad.

"Unable to checkout. Try again later." Can't upgrade my account because of Klaviyo's system issue. Can't contact support until I upgrade. Can't upgrade because of a system error. Complete and utter joke.

Extremely unhappy. Klaviyo is an OK email service, it is not super user friendly or smooth, it get's the job done. Last year, my monthly price went from 80usd to 150usd. And if I pause and resubscribe, it would be 200usd. That is a 250% price increase. During slow periods now, I cant keep my costs low, because then they will squeeze more money from me. I would be very cautious picking klaviyo today. They are in a phase now of just capitalizing the living hell out of their customers. I am looking very hard to get out, and never come back. My energy to trust the company even if they adjust the prizing in the future would not be there. So be cautious, if you get on their payroll, they will use you as hard as they can, and it is probably not great for either your or their business long term. they are moving into a charge method when they want to charge you like they do provide the sales, but they really don't. They help send emails, the rest of all services are nothing unique at all. Meta owns their traffic and sells it to you. Klaviyo helps you communicate with your costumers, but they want to charge you like they also own the traffic. But they don't. Your customer lists are yours. Not klaviyos. They do not bring this value. Be careful, and if you sign up, get ready to get used as hard as they can to get all the money out of you. You will end up in a annoyed frustrated position, the more dependent you get on them, the more they will take advantage of you as time goes by. Think of it like telling a secret to your best friend, and then they will start blackmailing you not to tell it to somebody else, that is the feeling you will have in partnering with klaviyo.

Waste App: emails delivered (12694) - opened (1009) - clicked (13) - unsubscribed (111) - marked as spam (18)... no comments for usd375

A nightmare to setup, zero support, stay away!

Klaviyo stated they have protections in place to keep bots from signing up creating fake emails. I am a small business and my email is full of fake emails. I try to delete them but they don’t disappear. I can’t keep ahold of any one in support until I upgrade and pay a monthly fee or lower the amount of emails in my account which is not working. I guess you can’t get help unless you pay them. It is a difficult platform to use also. The best option is to delete my entire account and go to a different email provider. I don’t want to work with a company that can’t help unless you pay them!!

I used Klaviyo for years between 2018-2020 and I was happy with it despite the high costs. More recently they introduced caps on how much you can email before going to the next tier, and their caps are extremely restrictive compared to other ESPs. In order to send 5 emails a week to my entire list costs me double what I'd pay in my tier normally. So for 2000 contacts I'm paying $100/month to send what I want to send. I'm not against a (good) company making money, but their cost is roughly $1 for 10000 sends and they charge you 20x markup just on the sends. This is absolutely ridiculous and their prices don't justify this when you have better and cheaper options available. I'd stay far away from them. Edit: Lol at their generic ChatGPT response - they are clowns.

ABSOLUTELY HORRIBLE. Do Not Use these guys. Go to MailChimp or whoever else. But def not here! I'd give half a star or zero if I could.

Expensive hidden costs. Unsubscribed and uninstalled a long time ago but they keep sending spammy emails saying 'account limit reached'

Klaviyo kan åbenlyst en masse ting, men hvis man har unikke domæner tilknyttet sine markeder i Shopify market og har brug for at sende flows og mails ud til kunder i de forskellige markeder så kan man kun gøre det fra et branded mail domain. Det virker besynderligt i 2026 at få besked om at købe 4 x Klaviyo konti, når man har samlet sine markeder i Shopify netop for kun at have 1 webshop. Alternativt foreslog Klaviyo også at jeg kunne få en udvikler til at lave et helt setup. Det så meget indviklede og meget dyrt ud. I øvrigt har jeg fra "Klaviyo" ekspert og selveste Gemini fået at vide at det godt kan lade sig gøre, men det kan det ikke når man så står med problemet og ønsker det løst.

Scammers! I was charged $390 when suppose to be $45 They mislead your in their settings that you wont be charged if you exceed your limit, but you will be so be careful! There conversions metrics are also highly exaugurated. Out of 12 conversions they claim i manage to confirm only 3. Go to other services llike PushOwl, do not use this scammers!

Absolute scammers! BE CAREFUL with this guys! I setup in my Klaviyo settings not to be charged if i exceed my limit of $45 plan. I was assured by their support that i will not and then after just 30 days they were about to charge me more than $600 Thankfully i found out before the charge and canceled the service! Do not trust their settings. They purposly play with words to trick you thinking the "stop" in their settings is for the "profile and email" plan, but its only for the emails and if you exceed that limit you will be charged, in my case a LOT! Scammers, do not trust their support too! btw, they also show you misleading conversions - claiming the conversion is made from Klaviyo when it's clearly from other source and Klaviyo email was not even opened by the customer!

I followed explicit instructions from Klaviyo support to resolve a configuration issue. That guidance resulted in service interruption and an accelerated billing cycle. Despite clear communication records, this is now being treated as a “customer-initiated change.” This is extremely disappointing and uncomfortable as a paying customer. I hope Klaviyo will review support-led actions more responsibly.

Klavio would't import my subscribed email list. It's how to import contacts from shopify instructions absolutely did not work.

Horrible. Faites super attention à votre forfait. Je ne l'ai pas pas surveillé, résultat : 2 mois à 375 dollars pour un ROI de 50 euros max. HORRIBLE. Vous choisissez le plan gratuit, vous n'avez aucune notification par email pour le changement (le comble pour une app emailing).

We are unsatisfied by the set up and ease of use of the Kaviyo SMS app. We have been locked out of our account and cannot access the app or are unaware of our status and customer service has not responded to requests to unlock account. Rating Poor, unresponsive, challenging to use.

I’m really unhappy with this app so far. Expecting users to pay for basic human assistance is unacceptable and leaves a very poor impression.

Atrocious customer service that has no basic knowledge. They don't even know what z-index means. Also, the smart translate feature is completely buggy. It translates some parts and leaves out others. Even mixes languages within 1 email. Ive been using Klaviyo now for 2 months and was better off with Omnisend. It was also cheaper with basically the same functions. What a waste.

Terrible app, we used to use it for sign ups, haven't used it since 2021, when after i deleted the app, thousands of fake emails got added to the list. I've been trying for hours to delete ALL customer's data, as well as all these bot email accounts with no success, can't even get support for it and refuse to pay to get it. the profile maintenance page is blank. just trying to comply with the LAW on customers data

I have paid for a plan and in the same date they have created me an invoice and i have told them that the invoice is incorrect and it needs to be changed, they said that the past invoice cant be changed, only the future ones if i modify in the settings the company name, etc. But i have requsted this in the same date when they have created my invoice, i dont understand why it cant be modify, its unbaliveble how they cant change the invoice.

The scheduling of pop up is faulty and does not work.

Simplesmente não funciona no Brasil, nem deveria estar disponível.

So many restrictions on the new klaviyo customer hub. I can integrate gorgias, but not their live chat. Now klaviyo expects me to pay for the helpdesk feature AND also gorgias? Why? Also no mobile app for the helpdesk.

Be careful when using their email templates. They add default ALT text of the original image and include a link from some other company within some templates with animated pictures. Unfortunately, I realized this only after sending an email to my customer list, and now my customers received an email where the main clickable image leads to a completely different website. Those ALT texts and links shouldn’t be added to the templates. The services of your partner should be advertised in a different way not in a hidden way within templates!

Is this fraud?- Klaviyo Secret Sending Limits & Poor Transparency — Be Careful I’ve used Klaviyo for over a year and feel other Shopify merchants deserve a heads-up about something Klaviyo never discloses: Klaviyo will charge you for contacts that it will, without your knowledge or consent, refuse to send your emails to if they deem that contact is unlikely to open/click your email. Klaviyo takes your money then quietly gates or throttles your campaign sends, meaning your emails simply do not reach your subscribers — even though you’re paying full price for that list size. In my case, I had an 8k active list (with 30k suppressed), and Klaviyo still withheld delivery of many campaigns. Open rates were low because emails weren’t actually reaching inboxes, not because of strategy or content. Klaviyo’s dashboard shows “Poor” reputation, but the platform does not explain that this means your send volume will be internally limited. Klaviyo support misdirects you into thinking its all about YOU, the quality of your emails, etc... while not telling you that it's also because they just don't send your emails (their discretion), period. This makes recovery nearly impossible. You’re stuck paying for a list you cannot fully email, with no straightforward path to fix the issue and no warning that this is happening behind the scenes. Klaviyo can be powerful, but this lack of transparency seriously undermines trust. After switching providers, my deliverability improved immediately — confirming the issue wasn’t my content or audience. If you’re a Shopify merchant whose income depends on reliable deliverability, be aware of Klaviyo’s undisclosed internal limiting system. It can cost you months of lost revenue, while you’re still paying for contacts you can’t reach. Someone should really investigate this practice, as it seems like a class action waiting to happen.

Hectic experience. They hound you until you sign up but then dont respond after you sign up and make the payment. Been dealing with their sales person Sulaiman Lodhi and its our worse experience with an email app to date.

After subscribing and making payment, I was unable to access my account for two full days. Despite multiple attempts to reach out, their support team offered absolutely no effective solution. Extremely disappointing experience.

My Klaviyo account was hacked, and trying to recover it has been an exhausting experience. I’ve provided every possible piece of verification they asked for — except one email address I’ve never even seen before, which is the whole reason I need help in the first place. Instead of helping resolve the issue, support keeps passing me from one representative to another with no continuity or progress. For a platform that manages customer data and email security, the account recovery process should be far more user-friendly and reliable. This has made me seriously reconsider using Klaviyo at all. As it is, I did not find the app very user friendly or beneficial.

Es ist und bleibt schwierig, Ein Upgrade des Abonnements kann nur mit Kreditkarte durchgeführt werden. Wird kein Upgrade durchgeführt, kein Support der dazu was sagen kann. Wird keine Kreditkarte hinterlegt, ist kein Upgrade möglich. Das ist ja was ich hier schreibe. Man bekommt eine Antwort die nicht das Problem löst. Ihr wollt, dass ich ein upgrade durchführe, dies ist aber nur möglich wenn man eine Kreditkarte hinterlegt. Habt Ihr dafür keine andere Möglichkeit? Es bleibt bei einem Stern.

Great application with the absolute worst tech support I have ever experienced. Confused about their own product, non-responsive, and basic help takes MONTHS. I have been dealing with an issue since essentially day 1, and it still is not resolved. Expect weeks to go by without a response. Expect to repeat yourself 3-4 times every time your issue is escalated because apparently they don't read notes. Expect the help to not solve the actual issue, and have to repeat the entire process again. If you are not tech savvy and adept and implementing solutions yourself, BUYER BEWARE. You are on your own.

Horrible, money hungry company. If you don't pay up front, you get no support whatsoever. I can't even ask support a question until I hand them over my money. Sickening. Integration was not seamless at all either. Took forever and then they said our industry was prohibited when we tried to set up SMS. WHAT?? Natural Skincare?? WOW.

Unfortunately, I'm not so impress with this app. The Klaviyo app is not working on my default Shopify theme page. I've been trying to get someone to review the app configuration and its taking them days to solve the problem. They are so slow at responding to issues.

i need to pay $100 a month because i have 5000 contacts in my email list lol this must be a joke

I only installed the app to explore the features and now they are sending me notifications that I need to upgrade to premium. I haven't even created an account. Terrible app.

Plus vous allez avoir de client plus ils vont vous facturer et vous changer de plan sans vous demander. je suis passé de 20€ à 90€ par mois !! Pourtant j'envoie tres peux de mail par mois !!

i've never seen an application too bad like this before iml. And there is no turkish language support. And I always face new issues. Again and again

The email marketing itself has personalisation for wholesale B2B business so you can refer to their business name, which is essential. That is the ONLY reason I am currently using them. But I am completely unimpressed with their billing ethics. I uninstalled Klaviyo last month on the 16th and received an email confirming I had permanently closed an account, and then received another bill on the 17th, and the 17th of this month. When you permanently close down a website Klaviyo manages to keep billing you for non-existent email services. I have been billed on two different credit cards, five days apart for supposedly the same website with different email addresses. I guess the only way to stop this is to cancel my Visa and Mastercard until it all stops, and then re-establish payment on one card, once a month. I would seriously like to find a decent replacement for Klaviyo.

I just purchased a package, but the next day I couldn't log in. It kept asking for a verification code, yet it never sent the code to my email. I've checked my inbox multiple times and still haven't received it. This experience is terrible—it's not worth the money.

I've been a customer for over 4 years and I can say the support has alway been subpar but now it's terrible. I've also incurred unauthorized account charges and now they auto-sent already delivered campaigns damaging our reputation. I would seriously consider using another app for the cost alone but the lack of support really makes the decision to go elsewhere easy.

I signed up for Klaviyo’s $20/month plan (500 profiles, 5k emails). On August 24th, I even received an official notice confirming that my $20 plan would renew on August 26th. However, Klaviyo automatically upgraded my account to a $125/month plan just because the system counted extra “profiles” that I never actively used. I only send around 5,000 emails per month — completely within the limits of the $20 plan. Yet I was told I must first pay $125 and then request a refund if I want to go back to my $20 plan. This is unreasonable and unfair. Klaviyo’s billing model is designed to trap you into higher tiers based on inflated “profile counts” rather than your actual usage. There is no option to opt out of auto-upgrade, and support refuses to prevent this from happening again. If you are a small business expecting predictable costs, be very careful. Klaviyo may automatically charge you far more than you agreed to without your approval.

Klaviyo is extremely expensive, yet their support feels arrogant and useless. Instead of solving real issues, the support team seems focused on closing tickets with vague answers and tricks to push you away. Meanwhile, the platform creates massive problems. In our case, customers abusing discount codes and causing endless order headaches. For nearly €500 a month, this is unacceptable. Shopify Email is not only €500 cheaper per month, it also works much better.

I find it hard to imagine that Klaviyo, a major company, could create an app so riddled with bugs. My emails couldn't get customers to my website, a feature that even a $5-a-month email marketing app could provide. But in the eyes of Klaviyo's software engineers, this was an insurmountable obstacle. This was an unforgivable mistake. Klaviyo's new feature required me to enter my phone number before logging in. I don't understand which incompetent engineer came up with this.

Charged me £75 gbp despite cancelling then wouldn't allow me to access to use the service for the month i paid for. Not user friendly on iphone only laptop.

ZERO actual help...but a whole lot of emails about reviewing them. And they're still sending me a bill after uninstalling over a month ago.

does not work support could not even help install beware will not give refund support did not know there were 15 setup actions. setup error caused website to be shut down 3 days while i figured out fix and support said it wasnt their problem. i would give negative 5 star if i could. $600 loss and shopify credit refused refund that any other card would have graanted

Two days worked then no login. The verification is not being sent to the email. How can the first and foremost task of a user be problematic? No one tests this section of the app?

Very sketchy pricing. My $500 plan jumped to $950. We are chargebacking as they refused to work with us even though it was their systems issue.

klaviyo get really expensie ! you always need to reupdate your pricing. it ll be ok if the customer service is reactive but the customer service is just an AI that is not even set properly !

customer service is really really really bad .... talking to a bot that is not even set properly, again these companies rely on AI but are not able to assist their customer who pay few hundreds per months ! Also they increased their price alot ! before it was based on email sent now on the size of the number of customer. i mean if i pay that much i expect at least a quality service. really really bad guys, you have bad customer service

False pricing plan. If you open pricing plan from the app page, then you will see that you can buy 20$ plan with 5000 emails. However, after installation I've tried to update plan, and the cheapest version is for 140$ only!

Overpriced and useless if you're running a multi-lingual store. While they offer email translations, which are fine those are useless as one cannot translate the newsletter popup banner at all. After multiple attempts to talk to customer service, they said it's not possible.

ultimamente muchos problemas. no puedo entrar a mi cuenta. desde hace unos dias que no puedo entrar y hacer ninguna campaña

Beware of their predatory billing system. If you accidentally exceed your usage, they automatically upgrade you to a higher package for the entire next month without any warning, notification, or reminder. You have to manually downgrade it yourself or you're stuck with the extra charge. Even worse, I exceeded my usage on May 2nd and immediately reset it, but they still charged me for overage on May 3rd, applying it to the next billing cycle. This is not just careless—it’s outright deceptive. What was worse: I contacted to the support and asked for a refund of the $25. They refused. I seldom write a negative review of any business. Klayvio is just absurd. I just hope that any small business owner can find a good alternative. If you do, feel free to share it. I am going to share this post on Reddit as well.

Once you are signed up, the customer support disappears completely. I got a new device, cannot login via MFA, and their solution is for me to contact support, which requires MFA authorization. This app is not user friendly and the support is awful.

They Steal Your Money - They Change their Pricing Policy to Gouge their Customers by going from emails sent to active profiles, raising prices by 2x to 10x - Despite committing to a plan, they will upgrade you without your consent and charge you

The app imports all users indiscriminately, including those from imported Amazon and eBay orders, and so on. As a result, the number of profiles increases several times over, and the cost of using the app rises accordingly. These profiles are useless because they do not even have real contact information. It turns out to be a waste of money. Support is useless, and the online chat is unavailable unless you pay. The average response time by email feels like a year and a half. I used another app that costs twice as little, and there was no such problem — everything worked out of the box.

By far the worst app I have used so far. I am not sure how anyone can give this more than one star. Too expensive for what you get. Horrible menue/navigation. The setup is overcomplicated for no reason. Even after 2 Klavio experts looked into it, several things are causing problems and are not working properly. Can't just pause my plan to fix the issues. The platform is loading very slowly and getting stuck regularly. It cost us lots of money and we had lots of upset customers. I had this professionally set up for our business. We had several issues with the system not doing what it was supposed to do. The first company looked into it and was able to fix some of the issues. We hired a second Klavio expert who was able to fix a few more, but we were still finding issues where customers get discount emails, follow-up emails, even though they had already completed their purchase. We tried to pause the plan to fix this - not possible. We had to delete most of our accounts, which was a nightmare to do with their inefficient system. That should have put us on a free plan until we would have been able to fix the problems, but no, you have to cancel your plan first. While choosing to cancel our plan only not our account, going through the steps, it deleted our whole account. $6000 in expert costs of setting up this useless platform - gone! We used this nightmare for 2 years.

the absolute WORST app I have EVER used for ANYTHING. One problem after another, you "fix" something and another issue comes up. Customer service does everything but provide the way to fix it. They all genuinely have no idea what they're doing. Do yourself a favor and look for a different app like Mailchimp or something cause this is the biggest piece of shit app I have ever used.

This is the worst app I have ever seen. It is horrible. Nothing works like it's supposed to. Why would anyone ever want to use this app? No native integration at all. This is stupid.

I recently experienced an utterly disappointing situation with Klaviyo. After sending an important email through their platform, I discovered that Klaviyo had inexplicably broken all of the links included in the email. Naturally, I reached out to their support immediately. Their response? They said they'd need to escalate the ticket to resolve the issue. Frustratingly, the next email I received was a notification stating they had closed my support ticket—without even discussing the matter further or confirming any resolution. Not only did this leave my business in a tight spot, but it also highlighted Klaviyo's inadequate support structure and lack of accountability. For a platform that markets itself as reliable and customer-oriented, this kind of oversight and dismissive handling is completely unacceptable. I strongly advise anyone considering Klaviyo to reconsider unless you're willing to risk similar disruptions and disappointing support experiences.

Se quedaron con 10 días, porque facturaron antes y no me dejaron completar el mes. Me robaron aprox 100 usd o mas... Una lastima porque la app es buena.

I actually find it absurd that in order to get email or chat support I have to upgrade my plan?? "Your access to email support and live chat has expired. Check out plans for pricing and upgrade options."

Terrible customer service and it is not worthy for your money! Also, they do not return your money if you pay and decide to cancel the plan (we cancelled at the same day as we were charged and they have told us that are not refunding! !!)

Their new charging rules are very user-unfriendly, and their customer support is very poor, and the response efficiency is very low. Friends who want to use it, please consider carefully!

I have been using this app for some time now for multiple webshops. We do not focus so much on sending email campagnes so using a lower tier plan always was fine for us. Just before they announched upgraded their plan systems (ofc in a way they would end up making much more), we decided to up our plan ourselves for one store to start creating more campagnes and see if that would stick. So we got an email saying: our plan is 100 going to 150 with discount 25 = 125. Which is doable. Now just a few days after all the changes, it appeared that we grow just enough to go up in plan again. which means we are now paying 200 (-25) = 175. After deleting some sleeping customers it is not able to go back to the plan they told us we would be in. Basically we went from paying 30 a month to 175 a month in less then half a year. I guess having tons of customers and earning millions is not enough. Getting it from the small webshops you try to help is the way to go. I am definitely going to explore sending mails with shopify itself. Great service and very excited about the big guys trying their best to keep it real.

Very dishonest company, emails are sent out claiming you can adjust your plan (because they auto upgrade you) I was told I can surpress my lists only to be told later you are no longer able to surpress lists. They refused to give me a refund so I am taking up with the bank!! Do not use them for emails! They make it very complicated to take your money.

I can't believe they are starting to bill based on "active profiles" instead of emails / sms sent. What an absolute money grab that doesn't help businesses grow! Limit Customer / Merchant Growth = Limit Klaviyo's Growth. Not sure why that isn't straight forward. Going public for them was a mistake if this is the direction they chose! Come on Klaviyo! Get it together or lose a lot to your competitors.

Been using them for over 3 years. Between the price changes and the declining customer support, not to mention the LOW deliverability that they have, it is not worth it -- save your money and go elsewhere.

Is it usual for the customer (me) to raise a support request and for that request to be closed within 24 hours without any response? Not the serivce I am hoping for looks to be $400USD per month.... update: Opened a second support request and again closed without being contacted....wow...smh.

I've been using Klaviyo for three years, but I'm switching to Shopify Email due to their recent cost structure changes. The pricing has become unreasonable, especially for small and mid-sized businesses. There are more affordable options that offer similar functionality without the excessive costs. I’d recommend others consider alternatives to avoid the unnecessary expense. Speak with your wallet. Klaviyo's price hikes are unacceptable.

Absolutely terrible service. Quick to constantly upgrade your account which cost more money but trying to get someone to help you is nearly impossible. Onboarding was fantastic but after that everything went downhill. Plus my conversions have never been as bad as they are with Klaviyo.

With their pricing changes, we have to pay TEN TIMES more than before. I received this message four days before the new price change.

Klaviyo recently sent an email to say that starting February 18, they will change their pricing policy from emails you sent to ACTIVE profiles that you have. Making my current plan 8 times more expensive than what it was before. I was sending emails to 5000 people only but have 30,000 active profiles. I contacted support about 3 tims to try to understand who those 30,000 people were exactly. One staff from the support tells me in order so know if they are good emails, you should make a test and send an email to everyone and than create a segment to be able to find the inactive profiles that I should delete. I did that. Automatically Klaviyo charges me 800$ (I was paying from 60 to 100$ per month for the last 4 years). I contacted support again to understand and lower my plan. I asked for a credit which an agent called Naranjini confirmed that she will give me. I was able to lower the active profiles from 30k to 15k within a week. This was really time consuming for me. Than Naranjini told me to take my time to clear up my list because I was really busy with the daily operations of my business and that the credit will be appled anyways. The ticket opened by Naranjini got closed automatically so I cannot contact her again to follow up with the credit. So I have to open another ticket with someone else and reexplain the whole story. I did it. Than it got transferred to billing. A guy called MATT sent me an email saying that I now do not want to reduce my plan (WHICH IS COMPLTELY FALSE) and because of that no credit will be applied. He is not aware of the isue and has not read my conversaton with Naranjini. In the email he tells me I am using 30k profiles now. Which is also wrong because I have 15k profiles in my account at the moment. He has not taking my request seriously, has not read anything and changes completely from what Naranjini had told me in the chat transcript. After more than 4 years of being a loyal customer, Klaviyo just lost me ... Im going elsewhere

Leider können wir die App absolut nicht empfehlen. Egal für wlechen Shop ich Klaviyo verwenden. Jedes, jedes, jedes, jedes mal suche ich nach dem Link um die Subscription Seite direkt aufzurufen. Unglaub das dieser so schlecht zu erreichen und versteckt ist!!!!!

Gettting too expensive

They extremely increased their pricing again lately, not a legitimate solution.

Terrible changes to pricing!!! RUN AWAY and save your money! We have been a Klaviyo user for around 3 years now. We have around 13,000 active profiles in our list but we generally never send emails to all active profiles. We are on a 1000 active profile plan which allows us to send 10,000 emails (plan price $30/Month) and we are ok with these numbers. Now Klaviyo decides they want to make more money so on February 18, 2025 they are going to force us to move to a higher plan with 13,000 active profiles with 130,000 email sends automatically (plan set at $300/Month), that's a huge and unjustified jump especially given that we are not utilizing our current monthly email sends limit anyways. Honestly, these pricing changes do not make any sense given that the number of active profiles are simply data points in a database that costs Klaviyo nothing to keep. You should be charged for the number of email sends and not for the number of active profiles in a database. Totally non-sensical and greedy move! Save your money and move to another service at this point honestly.

Déçu par cette application Qui Surfacture et Harcèle Après Avoir Rompue L'abonnement Vraiment Dommage

disappointed that they have changed their pricing model so that I am locked into paying for my entire subscriber list even if I am not utilizing the entire list. The price split between paying for active profiles and amount of emails means you will always overpay. I would suggest seeking a cheaper alternative which I am now forced to do in order to save money. a shame as I have been using klaviyo for close to 4 years. but there are much much cheaper options

I have installed this app after many months of research and had finally the time to set it up after Q4. And then I was in complete disbelief after they have updated the prices on 21.1.25. I should pay more than 600$ for over 35k "active" users. Why should I pay for users, that are don't even subscribed to our newsletter? I dont need to send out 350k emails a month?? The monthly fee should be calculated for the actual subscriber list/sent out emails per month. I got only 2000 active subscribers. You can't even talk to a real human beeing, unless you pay. I wanted a subscripton, but not with this incredible price politics. The chat bot told me to surppress all other accounts, that are not subscribed to the newsletter. Ok fine, but then I can't reach any customers that abandoned a cart, when they did not accepted newsletter marketing? This is not worth the money. Who did this price change and thought this was a good idea? Watching the reviews, I'm not the only one.. So I'm sticking to the free Email Program from shopify. You can setup flows aswell

Pretty useless customer service. Probably one of the worst I've ever encountered. I've spent weeks being bounced between different operators, going back and forth talking about the same thing and it just simply seemed like nobody knew what were they actually doing there. I was getting the same canned messages over and over again. The issue I had was so simple that should have literally been resolved in seconds, but here we are...second week now, and we are right where we started! Meanwhile I noticed they closed my case and marked it as "resolved" ha-ha.
