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.

After installing, the log in process is not working. I forgot my password so I reset my password. The link for resetting the password was received after an hour. Besides, verification code is not sent instantly. I have to wait almost an hour. By the time I typed in, it said "type valid code".

The app constantly stop working, not possible to log in. Customer support option shows an error as well.

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.

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

The worst decision that I took was use Klaviyo, is impossible to cancel. I don't recommend to use.

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

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.

It is both abnormal and frustrating that we cannot define what constitutes an Active Profile ourselves, nor do we have the necessary tools to effectively manage and clean our profile database. Specifically: • A large number of fake profiles created by bots are being automatically marked as Active. • There is no efficient way to bulk filter or delete these profiles directly from the profile list. • We are unable to set up flows or automations to remove these fake profiles. • And most critically, Klaviyo charges based on the number of profiles — which means we are at constant risk of being overcharged by 20–30% or more if we don’t manually clean up these fake accounts every single day. This situation is clearly unfair and unsustainable. We urge you to provide a solution that either allows us to: 1. Define and control what is considered an Active Profile; 2. Easily identify and bulk-delete fake profiles; or 3. Exclude clearly inactive or bot-created profiles from billing calculations. We hope Klaviyo will take this issue seriously and prioritize a fix, as this has a direct impact on customer trust and billing fairness.
