Klaviyo Reviews 359

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.

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.

The worst email marketing company in the market
and the wordst support 0/10

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 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.

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.

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.

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.

great support, everything is fine

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.

We have used Klaviyo for close to 10 years now. We are officially cancelling our account as of today. The lack of support for its high paying users is nothing short of mind boggling. Since implementing MFA, their support tanked. We cannot get access to our account as the SMS messages do not come. No matter how many times we try. We are told it can take 2-3 DAYS to get a response on this issue. The only way to get support is to create a ticket through zen desk and because they have little support, it can take days to now access your account as an owner. YOU ARE HINDERING MY ABILITY TO MAKE MONEY!!! Get a system that is functioning for customers first before you cut off all remaining access for communication. DO NOT use their system. You can bet I will be removing all contacts today and closing this account effective immediately. Probably the worst decision you ever made as a company!

Klaviyo is not as good as it used to be.
The inbuilt pop up option does not work on android and the connection with shopify does not work well. It also slows down shopify store speed. The support is not very good anymore - the chat option disconnects and it takes anyone days to respond on email. I would not recommend using klaviyo as your email platform research other providers.

Danielle helped me solve all my problems!

So I use their plugin on the free version, install and get my form on my website to test the system integration. All looking good, form works. Then the next day, the form is gone. So I triple check all troubleshooting. All is ok on integration double checked, but the form is not showing. So I contact SUPPORT. But you have to PAY for support!! WTF guys, we are trying out and installing your plugin and you want us to PAY to test the plugin??? What a scam. No. If there is NO free access to support at all when trying out and deciding if it is worth it, then no business! ...btw, bot was useless.

Scum of the earth email provider of retail scammers. Since the beginning of the year, I have been receiving over 75 emails a day from scam retailers that send their emails through klaviyo or klaviyomail. Working to get anyone that sends emails through them to be blacklisted.

Klaviyo’s New Pricing Model is a Joke!

We've been loyal Klaviyo users for years, but their recent change to charge based on active profiles—not just the ones we actually email—is an absolute joke. Penalising businesses for simply storing contacts, even if they aren’t being emailed, is beyond ridiculous.

This greedy move has forced us to look elsewhere for a better provider. We’ve always appreciated Klaviyo’s features, but this change is a dealbreaker. Do the right thing for what’s left of your user base—DO NOT charge customers just for having emails in the system that they are not actively using.

For any business owners considering Klaviyo, I’d strongly recommend looking at alternative platforms that don’t punish you for simply maintaining a list.

Departing from Klaviyo permanently. Spent $20000+ on email and sms marketing. Much of which some sms campaigns never delivered. I complained and they disabled my account for compliance and not responding. Disappoint and unethical for a public company. This corporation will cripple small businesses and not care - do yourself a favor and do not risk your customers for their greed. It’s sad they would do this to small businesses.

Disgusting corporate greed! Once again Klaviyo hikes their prices by over 25% with no corresponding improvement in the product or support.

No customer service, poor deliverability, overpriced, and simply not worth it. Our customers do not care from which ESP they receive their emails from. We are moving to Omnisend after more than 5 years with Klaviyo.
