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.

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".

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.
Thank you for your feedback. If you're having trouble suppressing active profiles to move to a lower tier, don't hesitate to reach out to our support team at Klaviyo.com/support. We're happy to help you with this process.

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?
Thank you for this feedback! Our team has replied to your support ticket - if you are not seeing this response I would recommend checking your spam folder. We are eager to get this resolved for you!

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

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!
Thank you for your review! Customers are required to be on an email plan that matches or exceeds your active profile count. We will show you a plan that fits the number of active profiles in your account, so if the plan you are seeing is $140, that means you have 6,001 – 6,500 active profiles in your account. If you want to be on a lower plan, we recommend suppressing profiles so they don't count towards your active profile count. You can also read more on our pricing philosophy here: https://www.klaviyo.com/blog/pricing-philosophy

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.
Thank you for your feedback. We're always working to improve Klaviyo and create the best experience for our customers, so we appreciate you sharing your experience.

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.
Thank you for sharing your experience and providing feedback. We apologize for the negative experience you had with us, and our Support Leadership team is reaching out to you.

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

You do not pay for suppressed profiles, but you maintain their data so you can understand the actions they have taken.

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.
