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...

We are loving Klaviyo Email Marketing & SMS. I am not the best at sending emails. Mostly because I don't know what to send, but I noticed that when I looked at my calendar view it gave my ideas for emails and SMS messages as well as task to do inside my business operations such as monitoring inventory and planning future campaigns and more. They are the best I've used so far.

Seamless integration with Shopify. A great way to target by segmenting customers. Complete ease of use for email automation with flows and targeted sending. User friendly email template creation and many more reason why Klaviyo is the best email platform

Es una herramienta muy útil. La asistencia a cliente es rápida aunque es a través de email, hay que esperar que te envíen la respuesta sobre la solución a cualquier duda, sugerencia a problema existente mediante email. Me encuentro a los inicios de la integración y hasta el momento todas las dificultades que he encontrado en el camino, las he ido solucionando con el equipo de Klaviyo. Recomendada!

Amazing costumer support!! Fast, knowledgeable and kind. Janelle went above and beyond to help me!!

We've been loyal Klaviyo customers for 5 years, investing $12,000 USD annually in their platform. Recently, due to a system error, the size of one of our segments was miscalculated right before our billing cut-off date, which meant we were unable to fully use the email credits we had purchased, and they expired. I contacted Klaviyo support just 3 minutes after the new billing cycle began, explaining the system error and requesting a one-time credit for the expired emails. Considering the nature of the issue and our long-standing relationship, I expected this to be a simple, reasonable request. Unfortunately, Klaviyo refused to grant the credit for emails we had already paid for. This has been a disappointing experience and, in my view, a clear example of poor customer service. Based on this experience, I can no longer recommend Klaviyo. Cheers, Florian Founder & CEO, Soundbrenner

"My experience with Klaviyo Email Marketing & SMS has been great by sending my customers personalized, targeted campaigns that drive engagement and boost sales. Through segmentation, I can tailor emails and texts based on customer behavior, ensuring that each message is relevant and timely. The platform's automation tools allow me to easily set up workflows, like welcome series, cart abandonment reminders, and post-purchase follow-ups, which have significantly improved customer retention and conversion rates."

I was on Salesforce Marketing Cloud before this role, and having only played around with Klaviyo for a few days I can't believe how much capability it puts in the marketing teams' hands vs needing multiple partners and developers. Would highly recommend. The customer service is so quick to respond and so helpful.

I've used Klaviyo for years now and while it can be more expensive, it is such a robust email provider. I recommend it if you're growing a list and a business!

The Klaviyo integration is great! We are just starting to tap into the features. In fact, we hit a road bump when an embedded form was not populating. Both Shopify and Klaviyo support jumped on the issue and worked through the solution. I was completely impressed with the hands-on nature of the support.

Klaviyo has been an excellent tool for our email marketing needs.The support team is quick and incredibly helpful whenever we have questions or run into issues.

Really good concept, but I personally found difficult to use, expensive and not very good in terms of emailing, all in all.. I would find an alternative!

Directly after installation, a phone call?? And then an email pressuring for a meeting?? Seriously? That's reason enough to delete the app immediately. I am very surprised by this approach. Please remove my contact details from your distribution list, I do not want to receive any more calls or messages!

Klaviyo has significantly grown our email deliverability & engagement rates. Its an easy to navigate platform with amazing customer success team.

I hate the Klaviyo app. I was forced to switch over to it when I hired an email marketing team last year and I wish I never left Omnisend. Klaviyo requires you to be an expert on their platform in order to be able to use it. I've been trying to modify a basic ORDER CONFIRMATION email, I just need it to show the variants of the products ordered, the prices, shipping, tax and total.. but it's so difficult to do!!! It shouldn't be so difficult to make a basic order confirmation email show the items ordered and the total paid... I will be leaving Klaviyo as soon as I can figure out how to migrate all my existing flows to a better platform.
