Review summary

Created with AI, based on recent reviews

Looking at 60 reviews, most reviewers were let down by their experience overall. Consumers noted that customer service is completely unhelpful, often leaving them stranded without timely responses or locking assistance behind expensive paywalls. Reviewers expressed strong frustration regarding unexpected price increases, confusing billing structures, and sudden account suspensions without any clear explanation. Though some reviewers were happy with the platform's overall email campaigns and integration features, they represented a smaller group. A few other people also appreciated the responsive customer assistance provided by specific team members during their usage. These consumers found the software interface smooth and easy to use for their daily digital marketing tasks.

I wanted access to the Advanced KDP features to integrate their webhooks into out system for out customers.
I asked support explicitely if subscribing to a basic plan and starting a specific free trial would grant me access top the webhooks. The support confirmed and I subscribed.
This was a down right lie as it did in fact not grant me access.

Scam Upgrade to $3300!

I’ve been with Klaviyo 5 years. We were paying $625/month. Today we received a bill for $2765 AND $625! When I got ahold of their online support chat they said that we have 400,000+ active profiles which is simply NOT true. We did not change anything and all those profiles were inactive. They are trying to scam us by somehow making all those profiles active which we did NOT do on our end! Trying to deal with their support team now, this is a scam!

Horribly deceptive

Horribly deceptive. I tried out their new review feature and just during the demo it sent reviews. No preview, no setup, no branding.
ZERO customer support was available. I will not be using them anymore.

Klaviyo is not trustworthy, they steel data

If you want to rely on your emails and automations, please don't use Klaviyo. There are many other alternatives.

They suspended my account without any notice. Not even an email saying that my account is disabled. I had to find out when I received a Zapier alert.

They are very vague about it and the worst part of all they delete all your data and profiles. I reached out to them on support and email but no reply so far regarding my data. I would have understand it if they suspend your account, but the fact that they steel your data and won't let you export it is a crime in my opinion. I will wait a couple of days before I take legal steps.

Ps Klaviyo. My account on Trustpilot is not the same as I have with you, so don't dispute this review saying it's not based on a genuine experience. I do have an account with you guys so it is my own genuine experience.

Poor pre-sale and got scammed

I was trying to see what automations this company offers - no information. Requested a demo, got an email to create an account, did that thinking it will be my demo, but no, I got trapped into creating a live account where I have to link my website and everything.
Went to the chat, it was Ai bot and real support is available only for accounts who pay for the service. So, how am I supposed to understand what this company offers before I buy it??? Feels like a scammer agency, no pre-sale support what so ever, lots of information, which does not offer enough info.

edit: Was just reading the reviews and it is scary. Gives me an impression of poorly organised company, when they only take action after a review has been left.

Thank you Truspilot for helping me not to choose this company.

Hi Eddy, thanks for your feedback. It can take a while for the sales team to get around to everybody who wants a platform demo, but there is a demo video on our homepage (https://www.klaviyo.com/uk/platform-demo) and you can also find detailed information about the automations you can build in the Platform section. Creating a free account is entirely optional - we offer this because gives you the chance to go into the platform and have a look around for yourself. There is no obligation - and it's not a scam. Nevertheless, we appreciate you taking the time to share your experience. Kind regards, Claire

Don't bother, you'll loose money and won't get any support

Don't know what happend but the last months there after sales services is totally ZERO. No help with bugs, no solutions, you have to repeat the problem several times, and you have someone on the other side that seems to not really understand what I'm saying or explaining, etc. What a waste of time.

We also got upgraded to another price but they keep changing their prices.

They used to be excellent but clearly not the case anymore. We're leaving.

After 9 Years, This Is How They Treat You

I’ve been a paying Klaviyo customer for 9 years. After the Christmas peak, I forgot to downgrade our plan. Our usage dropped, but we continued to be charged at a much higher tier — even though we didn’t use the additional capacity.

I hold my hands up — it was my oversight. But there was no cost to Klaviyo, as we didn’t use the extra service. I explained everything clearly and asked if they’d consider a refund for the unused months.

They refunded the current month (which hadn't ended yet), but refused to consider the identical previous months. No discussion. No flexibility. Just a copy-paste policy response and a flat “this decision is final.”

Even after nearly a decade as a loyal customer, there was zero goodwill. They charged us for services we didn’t use, and wouldn't make it right — even when it would’ve cost them nothing.

I can't see a genuine reason for Klaviyo's decision. They would lose nothing by issuing a refund as the services were not used. As a business owner myself, I would not treat a customer this way.

If you’re thinking of using Klaviyo, be aware: once they’ve charged you, that’s where the support ends. You’re on your own.

Hi there, thank you for your candid feedback - and for your 9 years of loyalty with Klaviyo. We want to make it as simple as possible for customers to manage their plan. While it's always been easy to upgrade or downgrade your plan to suit your sending needs, we've recently launched an auto-downgrade option for customers who pay by credit card, so that you don't need to remember to do it when your usage falls after a busy period. If you pay by card, you'll see this option available to you in the billing section of your account. Kind regards, Claire

Customer support does not help

Lot of issues - I keep opening tickets with Klaviyo customer support and nothing has been resolved. I am losing customers everyday as the click rate that Klaviyo shows is wrong as I am tracking the clicks in Clarity and clearly there are a lot of clicks that are not showing in Klaviyo.

HI Boomi, I'm sorry to read about the frustrations you've described. By default, all links - and therefore clicks - within a Klaviyo email are tracked (with a few exceptions). Microsoft Clarity is not designed specifically for tracking email clicks and may not provide accurate or detailed data for that purpose.

If you'd like to share a few more details about the other issues you've mentioned, please drop me a line at feedback@klaviyo.com, and I'll look into them. Kind regards, Claire

Is there some light........?

I would like to award more due to the fact of a couple advisors were brilliant and helped me set up a sign up form. This coupled with my own work and looking on YouTube, Casey Luck, i am now fairly proficient on Klaviyo.
The truth has always been the product is really good, with the caveat that it currently is not working due to technically issue for the last 48 hours? However it is potluck as to what advisor you get!! I have had live chat so many times, i eventually find a couple of good ones.
For this reason i can not give anything more than 3 stars, the level of competency within the support is still really poor throughout tho whole team, some shine brightly, others are awful!
Better but only because i have taught myself!!

If I could I would give them ZERO Stars. I have been trying to cancel my subscription for 2 weeks now. No success online nor with their Support. What they advise is useless and does not work.

In the meantime they are trying to deduct money from my card.

This is straight forward fraud! DO NOT USE THEM!

Klaviyo keeps changing its pricing…

Klaviyo keeps changing its pricing policies. What used to be a flexible usage-based plan has become a forced subscriber-based model, where you're pushed to pay for inactive profiles. You're left deleting users blindly just to avoid getting overcharged.

There’s no real customer support, no one to talk to, and no transparency. It feels like a company that's lost its way — no wonder their stock has dropped so significantly.

Hi there, thank you for taking the time to write a review. Our pricing has always been based on the number of active profiles a customer has, but we've recently adjusted the fees of those users whose active profile count exceeds their plan's limit.

You are only paying for active profiles - not inactive profiles - but you need to manage your list to make sure that inactive profiles are not being counted. We've shared lots of guidance on how to do this (e.g. https://help.klaviyo.com/hc/en-us/articles/24263920096027).

If you still need assistance, please reach out to our support team via the support link in your account. Kind regards, Claire

Great product but provokingly bad customer support

Great product, but the worst customer support that doesn’t match the very high price they charge. Every time I have been in touch with support, they either misunderstand, or close the case without resolving the issue. Is it AI-agents answering customer support tickets? This is reason enough for us to look for other options, this is too tiring.

Hi Vendela, I'm sorry to read about the frustrations you've described. Unfortunately it appears that you tried to contact our support team via two unused email aliases. Your messages will have triggered an email to you explaining that a support ticket had not been created, and explaining how to contact the support team (via email or by using the support button in your account).

It looks as though your queries were relating to account closure? You can read how to do that here: https://tinyurl.com/5fvp3kt8

Danielle M. is the BEST!

Danielle M. was AMAZING! I was really concerned regarding an issue with our most recent email campaign and I reached out to Klaviyo chat support. Danielle M. was incredibly patient, extremely knowledgeable, and made sure to answer every question I had to ensure I was feeling confident by the end of the chat. It truly was one of the BEST chat experiences I have ever had! Agents like Danielle M. are what keep me using Klaviyo. Danielle is an amazing employee! I am truly so impressed with their chat responses and for taking the time to help me and make me not feel rushed. I wish every chat agent was like Danielle M. - you are lucky to have her working for Klaviyo and representing your company so well!

$205 per month for a service that is subpar. My card declined because i got a new one and I went it to update the payment within less than 1 hour of it declining and it has now been 3 days and i have swapped to 3 different payment methods and emailed support and no one will help me process the payment to get my account reactivated and the "retry payment" button does not work on the site. TO PAY THIS MUCH MONEY AND HAVE NO ONE HELP YOU PROCESS A PAYMENT IS ABSURD. i have now lost out of many things in the last 72 hours of this service not being active. leaving and moving to a different platform.

Poor value for money

Im just not getting click-through at any measurable rate with this service. I already moved up a tier an support only suggests paying for an even more expensive tier. I have had far better returns from Shopify. Really does not live up to claims and modest expectations.

Terrible Customer Service

Like other reviews my experience with klaviyo customer service has been terrible. I identified spam emails syncing to klaviyo and requested details on how to stop this from happening and marking the profiles as inactive. Instead of helping with the issue klaviyo customer support advised that the new pricing based on active profiles "is a great deal!". How is paying an ongoing subscription for "active profiles" who have never consented to any email marketing and who provide no commercial benefit to my business a great deal. It is only a great deal for klaviyo! Despite emailing klaviyo for more than 30 days and klaviyo taking up to 10 days to respond the issue persists. I have not consented to increased billing and klaviyo customer service abruptly ended the call. I would not recommend.
