Pretty useless customer service. Probably one of the worst I've ever encountered. I've spent weeks being bounced between different operators, going back and forth talking about the same thing and it just simply seemed like nobody knew what were they actually doing there. I was getting the same canned messages over and over again. The issue I had was so simple that should have literally been resolved in seconds, but here we are...second week now, and we are right where we started! Meanwhile I noticed they closed my case and marked it as "resolved" ha-ha.

Really good customer services. Their rep Pete is super kind and help me out solving the issue in a short turnaround time.

Klaviyo has been exceptionally good for our company. We have increased sales exponentially while connecting with our customers on a personal level while expanding our customer base. The exponential growth adn future potential is unlimited. We are very happy.

I've been in email marketing for 18 years, and Klaviyo is BY FAR the best platform. In fact, I now only work with clients who use Klaviyo. And it pairs incredibly well with Shopify. I have a dozen clients and spend 10 hours a day in Klaviyo. Trust me, I know it well ; ) I'll be direct here: if you sell products or services online, Shopify and Klaviyo are the ONLY way to go.

Been using Klaviyo since the very start of the business in 2021. Now, with a change of pricing policy will be forced to move to another service. Absolute scam of charging $1k+ for "active" profiles that I'm not even sending emails to.

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?

Klaviyo Inc. regarding unfair and unethical billing practices. For the billing period of December 28, 2024, to January 27, 2025, I was charged $8,180.87, despite being enrolled in a plan clearly outlined at $4,088.50. I have provided Klaviyo with documentation confirming the agreed-upon amount for my plan. Despite this, the company has refused to issue a refund or offer any resolution. Their refusal to rectify this issue is not only disappointing but raises serious concerns about their billing practices and customer support. Additionally, upon further investigation, I have discovered numerous similar complaints from other businesses regarding Klaviyo's unfair and unethical billing. This pattern of behavior suggests systemic issues that need to be addressed to prevent further harm to consumers. I respectfully request that Klaviyo: Issue a full refund of the overcharged amount ($8,180.87 - $4,088.50 = $4,092.37). Conduct a review of their billing processes to ensure transparency and accuracy moving forward.

Crazy how you have to pay to get in touch with the support. For some reasons my flows dont work and there's no way to get in touch with the support. Really bad, would not recommend

With the right setup, Klaviyo can significantly boost your email marketing performance and drive revenue. Having worked with Klaviyo extensively, I’ve seen firsthand how effective it can be when used strategically. It’s an essential platform for anyone serious about growing their e-commerce business.

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. Update 5th January 2025: after a bit of back and forth with Klaviyo's billing team, and getting nowhere, I decided to leave negative reviews in as many places as I could think. Miraculously 2 days after doing this I had an email from their management offering me the refund they should have given me in the first place. Just goes to show the power of reviews I guess!

Matt was very patient and helpful. He spent the time asking more questions and we finally uncovered the issue. Saved me giving up and hiring someone to fix what was in the end just my knowledge gap.

Very user friendly! Once you find your way around the app and get used to the interaction, it is AWESOME and very responsive. Definitely looking forward to increasing our revenue through the flows. 10/10!!

If you need service and no one responds its Klaviyo. I have had the worst customer service or no service from this company. When you try to get help there is often no one on the chat and you wait and wait and finally give up after an or hour or two. When they want you to signup they are very fast in responding and you get impressed by how great their service is but after you sign up, no one is there to find you. Stay away as far as you can because after sweet talk, there is no talk.

ive dealt with many customer service agents across countless comapnies. Aurora provided me with one the best response, explains, guides, helps all in the response very satisfied!

Totalmente recomendable como herramienta de Email Marketing compatible con Shopify. Es una herramienta muy potente, aunque cuesta aprender inicialmente, pero tienen mucha formación y un muy buen servicio de soporte. De todas las herramientas de Email Marketing que he probado, ¡sin duda me quedo con Klaviyo! También para Marketing Automation tiene muchas posibilidades con Shopify.

es muy molesto que al desinstalar la aplicación, te deje residuos, que luego con un programador debas de eliminar del codigo de tu pagina web. muy mal por eso.
