My revenue is increasing every day. Wish I had done this much sooner. I resisted Klaviyo for quite a while, but I'm so happy with it now that I took the time to learn how to use it.

Fun and professional tool to use to keep in touch with your customers and to expose you to new customers.

This app is really well done and the support is phenomenal. I'm a beginner when it comes to everything email marketing and I've been able to place all my automation emails and email campaigns. It has taken some time, but I can't say enough about the support that is given with real people, any time of the day. I recommend 100%

I cannot recommend Klaviyo enough, it is simply a fantastic tool for email marketing needs. Their support is top notch, very knowledgeable and efficient.

Sell your soul to this application. Yes, it has functionality and integration; BUT once you are on the system they own you. The design it so that it's almost impossible to unsubscribe. You can downgrade and they will automatically upgrade you, charge you, fees all the time without your permission. But they will never downgrade you, refund fees, unused. Most importantly-- support won't help. They say it's a "self-service" platform so when it comes to just asking support to cancel your account. They won't. They send you down a rabbit hole, 10 clicks deep into pages, to find the one way you can cancel the plan. I'm a prisoner. Having set up my flows in the system, which they don't give you any option to export, unhooking will be very labor intensive. I regret, 1,000%, my decision to partner with this application. More importantly- support will not make CORRECTIONS to erroneous billing without double billing you! It's a total SCAM. I think this is CLASS ACTION LAWSUIT worthy... someone needs to shut these people down. They are stealing.

We've only just joined Klaviyo and have had instant success makes the process of email sales sooo much easier Thank you all from sanditoes.com.au

Klaviyo s'intègre parfaitement à Shopify et permet vraiment un contrôle inégalé sur le marketing par courriel.

A lot to learn but our systems have definitely improved since using Klaviyo. The help and tutorials and live webinars are so good. I always get the answer i need! Love it

Very interesting app. Very well made and structured. Easy to use. Solves all email marketing & SMS needs. Rich content and suggestions that make using it very productive. I had a minor problem with emails not sending that I couldn’t figure out. The support team was very helpful. Very quick response. They catered to my questions. And even shared solving the issue with the Klaviyo team as it was somehow intriguing. Thank you Andy for your help. Thank you Najah for finding what the problem was.

Klaviyo is such a buggy horrible integration that I'm going to try and get my client to change. I have a sign up form teaser on my client's shopify store that is not part of any sign up form. I've literally turned off every sign up form, every flow, and even disabled Klaviyo from Shopify, and still this Klaviyo teaser is the site. I've contacted support and got the typical copy and paste, go to sign up forms to delete your teaser but there is no live sign up forms, there is no sign up forms that use this teaser, it doesn't exist. Either it was deleted previously and the code still continues to be on the site without any way of removing it and Klaviyo doesn't want to help to fix their broken buggy product.

My experience with Klaviyo has been amazing. It is easy to use and seamless. My emails are easy to create and design. I have seen more traffic on my website because of the emails and that is always a good thing. I recommend this app to anyone looking to have an easy and seamless email marketing experience.

One of the best email marketing systems on the market. I am currently not using the SMS on Klaviyo, but it is on my roadmap.

Klaviyo has the best support system of any platform I've used. They're incredibly attentive and always provide clear, helpful assistance. I wish every B2B platform was as efficient!

We were struggling with list build and Klaviyo solved the problem! We have already garnered over $10K in revenue with our Klaviyo pop-up in just under a month. Highly recommend.

This service is absilutely amazing! Very intuitive to use with a simple UI. I've always used Shopify's email app and I never thought there was anything wrong with it or anything missing until I tried Klaviyo. It's so valuable for my business.

4 days of working to set up a simple landing page with an email capture form and an automated redirect after submission. Experience so far: - form editor is terrible - forms are not responsive across desktop to mobile (and editing for two platforms in the editor is a not usable) - limited logic capabilities moving through form submission flow - forms not saving consistently (it has been random for the past several hours) - forms not saving to designated lists - backend and admin is really unsophisticated and illogical - support (email, free plan) is slow, typically get the ticket closed type of support. In fact, in the past 36 hours, I have twice waited 12+ hours for a response and when the responses finally came I was called Nick and Kate (neither are my name) and the answers were not for me. I had to submit a second ticket to get a response to my first one. I could go one. There is a reason why over 10% of these ratings are 1 star So frustrating because I am now looking for a new solution to what should have been an easy requirement to solve

No support after starting to use paid version. We had technical problems and could not activate any features. Support was unresponsive, did not help to solve any issues, not even freezed the subscription until WE solve them.

Has to be THE WORST customer service I have ever encountered. No chat, no phone number, only email, which is promptly ignored. I've been waiting a week for them to respond to an account access issue. Can't do much if I can't access my account. No need to point out the irony of a marketing company that doesn't seem to understand that their customers, the ones that pay for their service, need prompt, helpful support every now and then. An update: It is now three weeks, and Klaviyo has still not bothered to contact me and assist with my issue. Nice try suggesting it is my mail server, this has been checked, the problem lies with this email marketing company that clearly do not care enough about customer service to provide either a chat or a phone number for help.

I felt overwhelmed and had absolutely no idea how to clean my list, or send newsletters and basically needed help every step of the way. Klaviyo support team were fantastic, they made everything so easy to do and understand. Highly recommend this app :)

Terrible customer service. Goes in circles. Very unhelpful people answering tell me why things are the way they are. The way they are isn't working...
