Klaviyo: Email Marketing & SMS

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

A Cataclysmic Change That Puts Long-Time Customers at Risk

I have been a loyal Klaviyo customer for the past 6 years, sending around 2 emails a week to less than 5000 contacts. I recently learned about their new policy that will charge me for every active profile—a massive price hike from $100 per month to $860 per month for hosting all my profiles. This change came with almost no notice and I now have less than 3 weeks to suppress over 75% of my hard-earned, paid-for email profiles.

Why would Klaviyo risk losing customers like me, especially after 6 years of loyalty? I barely use the service to its full potential—why should I pay for profiles I don’t actively use? This is an incredibly disruptive change, and frankly, it feels like Klaviyo has given no thought to how it will affect smaller, long-time customers.

I hoped Klaviyo would rethink this price change or, at the very least, give us more time to determine which profiles to keep active. But instead, I feel forced to look for a more affordable platform that can offer better value. For me, Klaviyo is simply not worth more than $100/month anymore, and I’m deeply disappointed in how they’ve handled this change.

Adding: Klaviyo response doesn't address my issues at all. More time to reduce emails would be much more appreciated than 25% off... Seriously? 25% off of $860/month? Are you thinking I'll just make the jump from $100/month to $645 per month?

disappointed that they have changed their pricing model so that I am locked into paying for my entire subscriber list even if I am not utilizing the entire list. The price split between paying for active profiles and amount of emails means you will always overpay. I would suggest seeking a cheaper alternative which I am now forced to do in order to save money. a shame as I have been using klaviyo for close to 4 years. but there are much much cheaper options

There billing is deplorable. You can't make changes to your account without being double billed. They don't do proration and then if you wait to change your plan at the end of your billing so you don't get double charged they will still charge you for the highest plan and tell you that they can't help you and you aren't owed a refund of the difference.

I call that theft. I downgraded to a $100 plan and entered my info to pay for that plan. Instead of it charging me for the new $100 plan I was charged $205. I reached out immediately to get the difference refunded. I was told that I paid the bill before I made the change which was 100% false because I updated the payment information after I made the plan change.

Klaviyo recently sent an email to say that starting February 18, they will change their pricing policy from emails you sent to ACTIVE profiles that you have. Making my current plan 8 times more expensive than what it was before. I was sending emails to 5000 people only but have 30,000 active profiles. I contacted support about 3 tims to try to understand who those 30,000 people were exactly. One staff from the support tells me in order so know if they are good emails, you should make a test and send an email to everyone and than create a segment to be able to find the inactive profiles that I should delete. I did that. Automatically Klaviyo charges me 800$ (I was paying from 60 to 100$ per month for the last 4 years). I contacted support again to understand and lower my plan. I asked for a credit which an agent called Naranjini confirmed that she will give me. I was able to lower the active profiles from 30k to 15k within a week. This was really time consuming for me. Than Naranjini told me to take my time to clear up my list because I was really busy with the daily operations of my business and that the credit will be appled anyways. The ticket opened by Naranjini got closed automatically so I cannot contact her again to follow up with the credit. So I have to open another ticket with someone else and reexplain the whole story. I did it. Than it got transferred to billing. A guy called MATT sent me an email saying that I now do not want to reduce my plan (WHICH IS COMPLTELY FALSE) and because of that no credit will be applied. He is not aware of the isue and has not read my conversaton with Naranjini. In the email he tells me I am using 30k profiles now. Which is also wrong because I have 15k profiles in my account at the moment. He has not taking my request seriously, has not read anything and changes completely from what Naranjini had told me in the chat transcript. After more than 4 years of being a loyal customer, Klaviyo just lost me ... Im going elsewhere

Klavio would't import my subscribed email list. It's how to import contacts from shopify instructions absolutely did not work.

Pretty crazy price increases on lifelong customers; we've been a customer since we ever started our business and Klaviyo has unfortunately become the only app in our stack that constantly increases their prices while adding 0 new features/functionality. it's good until you get up to ~50,000 or so profiles, then you should look to switch off of them.

Stay away and use someone else!

We've been with them for four years and it's gotten ridiculous. We had to spend 1200 for an email that had generated $200 in revenue. A complete ripoff.

There's better options. Support is the worst. At some point, they were the only players in the ecommerce game. Things have changed. Stay away because they will steal from you when you have actual volume.

Is this fraud?- Klaviyo Secret Sending Limits & Poor Transparency — Be Careful

I’ve used Klaviyo for over a year and feel other Shopify merchants deserve a heads-up about something Klaviyo never discloses: Klaviyo will charge you for contacts that it will, without your knowledge or consent, refuse to send your emails to if they deem that contact is unlikely to open/click your email. Klaviyo takes your money then quietly gates or throttles your campaign sends, meaning your emails simply do not reach your subscribers — even though you’re paying full price for that list size.

In my case, I had an 8k active list (with 30k suppressed), and Klaviyo still withheld delivery of many campaigns. Open rates were low because emails weren’t actually reaching inboxes, not because of strategy or content. Klaviyo’s dashboard shows “Poor” reputation, but the platform does not explain that this means your send volume will be internally limited. Klaviyo support misdirects you into thinking its all about YOU, the quality of your emails, etc... while not telling you that it's also because they just don't send your emails (their discretion), period.

This makes recovery nearly impossible. You’re stuck paying for a list you cannot fully email, with no straightforward path to fix the issue and no warning that this is happening behind the scenes.

Klaviyo can be powerful, but this lack of transparency seriously undermines trust. After switching providers, my deliverability improved immediately — confirming the issue wasn’t my content or audience.

If you’re a Shopify merchant whose income depends on reliable deliverability, be aware of Klaviyo’s undisclosed internal limiting system. It can cost you months of lost revenue, while you’re still paying for contacts you can’t reach. Someone should really investigate this practice, as it seems like a class action waiting to happen.

Been using them for over 3 years. Between the price changes and the declining customer support, not to mention the LOW deliverability that they have, it is not worth it -- save your money and go elsewhere.
