Klaviyo has been a very helpful platform for managing our email marketing and customer engagement. The segmentation, automation flows, and reporting tools make it much easier to understand customer behavior and improve campaign performance. What impressed me most is the quality of the customer service. The support team is professional, responsive, and always willing to provide clear guidance when we have questions. Their help makes the platform much easier to use, especially when optimizing flows, troubleshooting issues, or improving campaign strategy. Overall, Klaviyo is a powerful and reliable tool, and the excellent customer support makes the experience even better. Highly recommended for businesses that want to build stronger customer relationships through email marketing.

Extremely unhappy. Klaviyo is an OK email service, it is not super user friendly or smooth, it get's the job done. Last year, my monthly price went from 80usd to 150usd. And if I pause and resubscribe, it would be 200usd. That is a 250% price increase. During slow periods now, I cant keep my costs low, because then they will squeeze more money from me. I would be very cautious picking klaviyo today. They are in a phase now of just capitalizing the living hell out of their customers. I am looking very hard to get out, and never come back. My energy to trust the company even if they adjust the prizing in the future would not be there. So be cautious, if you get on their payroll, they will use you as hard as they can, and it is probably not great for either your or their business long term. they are moving into a charge method when they want to charge you like they do provide the sales, but they really don't. They help send emails, the rest of all services are nothing unique at all. Meta owns their traffic and sells it to you. Klaviyo helps you communicate with your costumers, but they want to charge you like they also own the traffic. But they don't. Your customer lists are yours. Not klaviyos. They do not bring this value. Be careful, and if you sign up, get ready to get used as hard as they can to get all the money out of you. You will end up in a annoyed frustrated position, the more dependent you get on them, the more they will take advantage of you as time goes by. Think of it like telling a secret to your best friend, and then they will start blackmailing you not to tell it to somebody else, that is the feeling you will have in partnering with klaviyo.

We use Klaviyo app for more than 5 years and it did help us recover the carts left by sending a series of abandoned cart emails. Welcome email, post-purchase follow-up email, and other customised emails, all help us bring in sales and grow steadily. Thank you so much for Klaviyo app which keeps releasing new features !!

I was unable to receive verification codes when logging into my account. Kalviyo teams helped me figure it out.

I'm unable to receive verification codes when logging into my account, and I've contacted suppor and submitted tickets t multiple times but without receiving any response. Very disappoint!

Found this to be far better than Mailchimp and they seem to be always improving the features and have so many options to customize your email design. I love how easy it is to set-up A/B tests, the integrations, the analytics, and the new AI tools as well, not to mention incredible customer service if you ever have an issue (or in my case, accidentally permanently delete something).

Aside from the fact that it is kinda expensive from what it offers, most of the services offered like help desk, reviews and email are all mediocre and mostly only offer basic features. It is also unneccessarily complex to setup at first. Once you do the initial setup, it is mostly fine to use but I would not rely on it for anything other than email maketing.

trying to set up 10% discount pop up for my shopify website has been a bit tricky. thought it was finished when a pop up says "Klaviyo onsite tracking must be enabled on your website to display your form." support says it needs to be done from the shopify website, shopify support says it needs to be done in klaviyo. It started off easy

I followed explicit instructions from Klaviyo support to resolve a configuration issue. That guidance resulted in service interruption and an accelerated billing cycle. Despite clear communication records, this is now being treated as a “customer-initiated change.” This is extremely disappointing and uncomfortable as a paying customer. I hope Klaviyo will review support-led actions more responsibly.

We switched to Klaviyo in order to use Email Marketing & SMS within one app and it has been such a smooth transition. We love the ease of use that the app offers as well as the customer service. We frequently attend their seminars and find their articles and resources very helpful.
