Klaviyo Reviews 359

I've been using Klaviyo since they were introduced to the market. In fact i suggested Klaviyo to many different friends and made sure at least 50-60 different company started to use Klaviyo.

Around 2023, we realised that Klaviyo wanted to be more and tried investing into completely useless things like user reviews etc.. This move created major concerns as Klaviyo was becoming a bloated solution.

In 2024 Klaviyo decided to go to public and this sadly marked the death of Klaviyo.

All. e-mail marketing solutions give you price offer according to the number of Subscribers you have in their systems. It was similar in Klaviyo but a clever director who want to receive stock bonus's tried to reinvent the wheel.

Klaviyo now wants to charge you for your actual customers whom have nothing to do with e-mail lists. But Klaviyo wants to charge you for that customer. Why? Because a director wants stock bonus's is more important than having a succesful long term business.

I am perfectly fine in replacing klaviyo, We will initiate our investigations as soon as possible.

Stay away from this money hungry company who will do everything in their hand to cheat you.

I've been using Klaviyo for over two years, but their recent billing change would have increased my monthly plan from $70 to over $150. I’ve rarely seen a company implement such a drastic price hike in all my years as an entrepreneur. It’s especially disappointing after investing so much time into building my email flows over the past year. I’ve canceled my subscription and warned other entrepreneurs about this abrupt change.

Terrible. Beware of their terms of service. I paid for my monthly subscription ($400!) then I decided to downgrade because I didn't want surprises in my statement. However, for some reason I can't understand, they enforced the downgrade immediately so I ended with 4 days of service when I paid for 30 days. Very unethical behavior.

I was hired to handle the email marketing for a client who only used Shopify Email in the past.

Because of its reputation of being a platform offering robust email marketing automations for e-commerce businesses, I wanted to transfer their marketing list to Klaviyo.

However, I had some questions on pricing, so sent an email to their sales department. I received an automated response confirming receipt and assurance my inquiry would be addressed promptly.

I waited-and-waited, but nothing. So two business days afterward, I sent a follow-up email.

Crickets.

So, I tried calling the number they listed on their site for sales (during their EST business hours) and a recorded message told me a representative would be with me shortly. After about 2 minutes of hold music, another recorded message came on, said something about reaching out by email (the same email I already sent a message), then it hung up on me. Called back, same thing happened. Called two days later, same thing!

I thought I'd send one last email asking for a reply, mentioning that if I didn't hear back from them, I would be sure to share my experience on TrustPilot. No reply, so I'm keeping my word and writing a review now.

Is Klaviyo even still in business?

If they are, this is definitely no way to acquire new customers.

If this is the way they treat you before you're even a customer, how on earth can you trust them to service your account once you do sign up?

Appalling customer service. Think I'll head to Constant Contact, OmniSend, or some other ESP who's actually interested in doing business.

UPDATE 1/28/25
In regard to your response, obviously I saw your online pricing, but wanted further clarification.

It's a moot point now anyway as I have zero interest in using, or recommending my clients use, your platform.

They shut down services without notice 2 days after I paid $860 for their monthly service. No explanation, no refund. Disputing with bank and reporting fraud to necessary departments here in the USA.

Shocking customer service from the douchebags at Klaviyo. Been with them for 3 years now. Generally all ok. However we've recently reduced the number of contacts/profiles in our email list quite significantly (by around 50,000). We expected this to have a significant effect on our monthly bills, but it seems Klaviyo is still taking out the same monthly amount as they were prior to the reduction in profiles.

I've spoken to them via live chat and email today, and was told that Klaviyo does not automatically adjust its billing down if the amount of profiles is reduced. Convenient. They were capable of automatically increasing our bills when our profile list was growing. But apparently they don't do this when the profile lists decrease.

Even so I thought that once I'd pointed out that we did reduce our list size last month, and therefore this month's bill should be significantly smaller (by about $550), they would agree to refund me the difference, but they basically told me to check my terms and conditions and get lost. They wont refund me the difference.

I am pretty dumbstruck by this. This seems very underhanded to me. Even if it's in the T's and C's to not do the right thing here stinks.

Obviously they've now lost all of our business.

Very expensive service for very little value add. AI-customer support bot with bad interface and non-responsive mobile design. We wasted our time and money here.

Long story short: DONT USE THEIR SERVICE!!!

I have used them for many years and Ive noticed how SCAMMY their billing system is. When your card is rejected and you pay lets say 10 days later, your billing cycle DO NOT PROLONG, so it actually means you're supposed to PAY FOR THE PERIOD, YOU COULDN'T EVEN USE!!!!

In honest companies, the cycle time is just moved and you are charged for 30 days of the service.

Guess what else - you can't delete the account or downgrade to free plan, there is NO SUCH THING. they constantly tries to CHARGE ME.

GUESS WHAT ELSE.
you cant even contact those idiots because there is no support if you dont have subscriptions.

FOR ME THIS IS A 100% DISHONEST COMPANY AND I THINK YOU ARE SIMPLY THIEVS.

EDIT: RESPONSOE FOR KLAVIYO

Of couse, Ive wasted time to check your documentation only to realise, this is not actual. I cannot do it by myself, neither delete my card so you no longer can charge me.

And of course, I tried to reach you, but guess what - I'd need to pay for the plan, so that I can access support. LOL. Riddiculus. Otherwise you offer only AI-generated support, which isn't helpful, since based on the article you've just sent, which is is not up to date.

WTF why am I wasting time writing this? This company is a crap with an extremely DISHONEST billing cycle.

The worst. Undeserving of even a one star. You can’t even add consenting contacts to your list segments as the functionality is dodgy and prevents you from doing so. Dodgy!!!!

I contacted the support team and they were unable to resolve the issue! This is incredibly dodgy software! Do not waste your time or money. If the success of your business depends on effective and reliable communication tools - look elsewhere!

After spending hours trying to make it work with Prestashop, it was impossible to do a proper integration with all the previous data from my customers. The technical team agreed this was a limitation. I had to move back to my previous email platform, lost money and time. They don't even reply to my demands of getting a discount.
I'm a experienced Prestashop developer, please don't choose klaviyo if you are using Prestashop.

In response to Klaviyo reply: It's not true that Klaviyo syncs all historical data, the newsletter subscription of the previous customers can't be sync, only the new subscribers. Klaviyo technical support already confirmed me this. This is totally unacceptable for a platform like Klaviyo, I can't understand how it can be the preferred option of Prestashop.

Non serious support trying to get us to contact google after THEIR integration between Klaviyo and Google broke.

The service was outstanding and provided significant assistance.

Error in one of their code files causing issues on client's homepage, as a developer I screenshot and documented everything and contacted support for a solution, was greeted with a customer service rep with an attitude and no solutions, tried to deflect responsibility entirely, told me they didnt know if they could help, just me. After my experience I thought I would check to see, if other customers had similar experiences. It sure looks like it, doesnt it? update: yes they did respond and admitting that the engineers knew about the problem and suggested we install 13 year old obsolete version of jquery to fix the problem, or break the entire app installation with an "updated" manual fix. Great work!

UPDATE: Yes you contacted me and asked me to upload a replacement file that broke the entire page, your development admitted they were aware of the issue but had no present patch, and no resolution was every suggested, the client switched server providers as the final workaround.

Dont bother! they draw you in then hit you with huge bills go forward and change your direct debit - then don't offer any help or refunds for overpayments.i cant add images here but my bills went from £339 to £936 in one month!! zero help or refunds. They should tell you you bill will increase to xxxx this month before it does and they do not!

This company has super powerful and intuitive products with many great features. They do participate in censorship business practices. If your e-commerce products are within their scope, this is probably a great choice. If your products are legal and are not within Klaviyo’s interests, recommend avoiding.

Every time your business gains 500 new subscribers (which I hope happens often for you), you’ll have to upgrade your subscription.

Way too expensive for what you get.

I'm actively looking for another software and will leave as soon as possible.

I can always count on Klaviyo support to help me out. This time, it was about a webhook that wasn’t working. No matter the issue, they respond quickly and always manage to resolve it. Thank you!

A Class-Action lawsuit needs to be filed on Klaviyo for numerous circumstances that surfaced with our corporation. It's incredibly sad that a publicly traded company would put small businesses through this level of anguish, despair, fear and failure. We were charged numerous times for SMS delivery campaigns and they never delivered. They changed the narrative numerous times, making excuses and much more. When we mentioned the legal implications, their stories started getting "straight" because we reached out to actual customers and built a case study of all the SMS deliverables we sent them. Factually, many SMS campaigns we paid for were not delivered which is thousands of dollars unaccounted for yet charged and billed. They admitted that it was because the "carriers denied them" and refunded in "good faith" according to them. Next, their "auto-upgrade" feature will send any small business into bad cash flow problems which happened to us today. They charged us $1730 after we downgraded and our monthly is always around $350-$450. Now I look forward to their response from their "escalation" team... Small businesses I recommend you unite together and not let a large corporation scare you. Stand up for your hard earned money because only you know what you go through and reach out to me if you have had similar experiences.

We initially switched from Mailchimp to Klaviyo, expecting more advanced flow options, even though Klaviyo’s pricing was double that of Mailchimp. However, it turned out that Klaviyo’s software couldn’t support some of these promised features. For instance, sending price-drop emails isn’t possible.

Since then, Klaviyo has significantly increased its prices and restricted the volume of emails customers are allowed to send, as well as limiting the maximum number of contacts. This approach seems designed to generate extra fees for customers. Their pricing structure is opaque, and you’ll likely end up paying far more than initially indicated in the contract.

If you’re considering becoming a customer, make sure to read all the fine print. There are several “easter eggs” hidden within, which will come back to bite you.

Just before renegotiations, they increased prices by up to 25%, and then tried to lock us into a two-year contract to avoid these price hikes. Given that these changes were made only a few weeks before our renewal, there was no time to migrate to another provider or warm up a new IP address. This makes it practically impossible to switch providers if the negotiation doesn’t meet your expectations. We were tied into an additional two-year agreement against our wishes and have since received extra charges repeatedly. Paying over $3,000 a month, we feel trapped.

Beyond the contractual issues, getting any meaningful support is a struggle. Responses from sales, account contacts, and support staff are standardized and unhelpful. For instance, it took us over a year to simply update our invoice email address!

STAY AWAY!
