Klaviyo: Email Marketing & SMS

Klaviyo Inc. regarding unfair and unethical billing practices. For the billing period of December 28, 2024, to January 27, 2025, I was charged $8,180.87, despite being enrolled in a plan clearly outlined at $4,088.50.

I have provided Klaviyo with documentation confirming the agreed-upon amount for my plan. Despite this, the company has refused to issue a refund or offer any resolution. Their refusal to rectify this issue is not only disappointing but raises serious concerns about their billing practices and customer support.

Additionally, upon further investigation, I have discovered numerous similar complaints from other businesses regarding Klaviyo's unfair and unethical billing. This pattern of behavior suggests systemic issues that need to be addressed to prevent further harm to consumers.

I respectfully request that Klaviyo:

Issue a full refund of the overcharged amount ($8,180.87 - $4,088.50 = $4,092.37).
Conduct a review of their billing processes to ensure transparency and accuracy moving forward.

If you need service and no one responds its Klaviyo. I have had the worst customer service or no service from this company.

When you try to get help there is often no one on the chat and you wait and wait and finally give up after an or hour or two.

When they want you to signup they are very fast in responding and you get impressed by how great their service is but after you sign up, no one is there to find you.

Stay away as far as you can because after sweet talk, there is no talk.

Crazy how you have to pay to get in touch with the support. For some reasons my flows dont work and there's no way to get in touch with the support. Really bad, would not recommend

I would give a 0 if possible. DO NOT SWITCH to klaviyo. We have been in business for 9 years and when we switched to K, our 60% open rate dropped to 20% and all of our emails land in SPAM. All they could say was it was losing consumer confidence and we have to do their "reputation repair" Klaviyo totally screwed us on all big sales. Any one have any idea who else would be a better alternative? Need to get out of klaviyo ASAP

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.

Does not supress marketplace order information like other app at a top level such as Judge Me. Extremely poor customer service and was advised that shopify is responsible for this app.

Shopify customer service has advised this is klaviyo's responsibility.

by far the WORST app on Shopify!

I want to cancel the $15 SMS package but when I do it myself the system cancels everything including my emails even though it is the SMS that I want to cancel. Weronika says that they cannot cancel this service on their side that I no longer want. IT LOOKS LIKE A HOSTAGE TAKING

Sell your soul to this application. Yes, it has functionality and integration; BUT once you are on the system they own you. The design it so that it's almost impossible to unsubscribe. You can downgrade and they will automatically upgrade you, charge you, fees all the time without your permission. But they will never downgrade you, refund fees, unused.

Most importantly-- support won't help. They say it's a "self-service" platform so when it comes to just asking support to cancel your account. They won't. They send you down a rabbit hole, 10 clicks deep into pages, to find the one way you can cancel the plan.

I'm a prisoner. Having set up my flows in the system, which they don't give you any option to export, unhooking will be very labor intensive. I regret, 1,000%, my decision to partner with this application.

More importantly- support will not make CORRECTIONS to erroneous billing without double billing you! It's a total SCAM. I think this is CLASS ACTION LAWSUIT worthy... someone needs to shut these people down. They are stealing.

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
