Klaviyo: Email Marketing & SMS

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.

We cannot recommend this app. If you want to delete profiles to switch to a lower payment model, it is very difficult and takes several minutes. The description link that Klaviyo sends you is not really useful. In fact, they try to keep you in the higher payment model.

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?

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

I contacted the customer service team because I kept getting error messages inside of my account and I let them know that I canceled the subscription back in 2023, and had actively not been using the subscription since 2024 which was verifiable and their campaigns. They REFUSED to give me my money back and mentioned in an email “ although you canceled your subscription, there is a back end that doesn’t allow you to fully cancel it without our approval”. Basically agreeing that I canceled my subscription but HAVE been charged for the last two years without any usage of the app but even if you have and showed proof of cancellation, “they have the last say”. Definitely do NOT recommend them

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.
