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.

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.

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.

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.

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! !!)
