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.

Hi Pat, spam is awful, and here at Klaviyo we enforce strict terms of use designed to prevent users from sending unwanted emails. We terminate the account of anyone who misuses our platform. Please contact me at [email protected] with the email address that is being targeted and the sender's domain, and our compliance team will investigate. We can globally suppress your email from all senders, if you wish. Kind regards, Claire

Klaviyo’s New Pricing Model is a Joke!
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.
Response from KlaviyoFeb 11, 2025
Hi there, thank you for sharing your feedback. Klaviyo's monthly pricing plan has always been based on active profiles. We're adjusting the fees of customers who have a higher number of profiles than their plan allows.
If you have profiles that you are not emailing, we highly recommend that you suppress them. You do not pay for suppressed profiles, but you maintain the data so that you can unsuppress to send communications to them at future times. It's easy to do - but check out this help centre article for more details: https://tinyurl.com/4sc7r63r. Kind regards, Claire

Biggest Mistake, $20000+
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.

Hi Ethan, thank you for taking the time to share your experience. I would like to learn more about what happened. If you'd be open to sharing some details please drop me a line at [email protected]. Kind regards, Claire

Disgusting corporate greed
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.
Response from KlaviyoFeb 4, 2025
Hi there, I'm sorry to hear that you intend to switch to another platform. It sounds as though the cost of your monthly plan is increasing because you have many more profiles than the plan you've selected covers. Where a customer's plan and profile count don't align, we are adjusting their fee accordingly - but increases are being capped to protect customers from large price jumps. Kind regards, Claire

Protect Your business and Stay away
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.
Response from KlaviyoFeb 3, 2025
Hi Mert, thank you for sharing your feedback. However, I'm concerned that you have misunderstood how our pricing works. Klaviyo's monthly price plans are based on the number of active profiles in your account, nothing more. (We explain what an active profile is here: https://tinyurl.com/3nh2trst). You are in full control of which contacts you consider to be active profiles - for example, you could suppress customers who have made a purchase but haven't subscribed to your newsletter, if you wish. Please reach out to our support team if you require any assistance with this. Kind regards, Claire

I've been using Klaviyo for over two…
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.
Response from KlaviyoFeb 3, 2025
Hi Wessel, thank you for writing a review - we'll be sorry to lose you as a customer. The price of your plan increased because you now have many more profiles than your original fee was based on. However, your actual price increase will be much lower than you calculated - our recent email explains how we protect customers when their plan and profile count don't align. Kind regards, Claire

Terrible
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.
Response from KlaviyoJan 31, 2025
Hi Lorenzo, thank you for sharing your feedback. To give you some context, our monthly plan is designed to be flexible, and so upgrading and downgrading is easy to do. That does mean that when you downgrade to a free plan, the change takes effect immediately. We explain this quite clearly in our guidance (https://tinyurl.com/4se78y9k) and via in-app notifications. Please look out for a further message from our billing team. Kind regards, Claire

Terrible - Absolutely No Communication From Them
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.
Response from KlaviyoJan 28, 2025
Hi there, I'm sorry to hear that you've not yet received a response from our sales team regarding your pricing query. Would you mind dropping me a line at [email protected] with a few details so that I can investigate why your message hasn't been picked up? (Also, if you haven't seen it already, the pricing information on our website may provide the answer to your question: https://www.klaviyo.com/uk/pricing)
