Danielle M was incredibly helpful and very patient with me as i navigated creating some segments and profile properties for my welcome flow. She was so helpful, continuously sending me examples, and even klaviyo blogs to go through the process, not only this, but she was helping me go through it step by step by providing me with answers, screenshots and double checking what i was doing. Amazing service, i'm so glad i always have help from the klaviyo support team.

the best, most intuitive tool there is. I have tried many email platforms, and they just don't compare. The ability to automate tailored mkt in klaviyo is simple, easy and intuitive

The app constantly stop working, not possible to log in. Customer support option shows an error as well.

Klaviyo provides so many incredible resources and is always quick to respond when additional questions; support is needed.

This is a must have marketing app! The look and feel of the emails alone is amazing, but it's the automation that puts this app over the edge.

A fantastic platform to use. The reporting functions and level of details it goes into is great. What's more, their tech team and response to issues is great and very thorough. We're really happy with it and recommend it highly against other popular apps we have used previously.

ZERO actual help...but a whole lot of emails about reviewing them. And they're still sending me a bill after uninstalling over a month ago.

Klaviyo has been a great tool for growing our email list. Our subscriber numbers and sales have dramatically increased since using Klaviyo. Our team loves it.

We switched from ActiveCampaign to Klaviyo – and honestly, the difference is night and day. Klaviyo is 100% better, more intuitive, and faster. Emails are sent out instantly and land in inboxes right away – no delays, no frustration. Once you get used to the interface and workflow, you’ll never want to use another tool again. Especially for Shopify users, Klaviyo is a total gamechanger: The deep native integration with Shopify is absolutely priceless – everything is connected, automated, and makes sense. Bottom line: If you're looking for a professional, high-performance, future-proof email marketing platform – Klaviyo is the way to go. German: Wir sind von ActiveCampaign zu Klaviyo gewechselt – und ganz ehrlich: Der Unterschied ist wie Tag und Nacht. Klaviyo ist um 100 % besser, übersichtlicher und schneller. Die E-Mails werden blitzschnell versendet und kommen beim Empfänger auch direkt an – kein Vergleich zu der oft trägen Zustellung bei anderen Tools. Sobald man sich ein bisschen an die Oberfläche und das Konzept gewöhnt hat, will man nie wieder zurück. Besonders für Shopify-Shops ist Klaviyo ein absoluter Gamechanger: Die nahtlose Integration in Shopify ist unbezahlbar – alles ist verbunden, automatisierbar und logisch aufgebaut. Fazit: Wer einen professionellen, performanten und zukunftssicheren E-Mail-Marketing-Anbieter sucht, ist bei Klaviyo genau richtig.

A little bit of a learning curve but I love Klaviyo so far. Its easy to integrate Forms and Reviews into my store.

We cannot recommend this app. If you want to delete profiles to switch to a lower payment model, it is very difficult and takes several minutes. The description link that Klaviyo sends you is not really useful. In fact, they try to keep you in the higher payment model.

does not work support could not even help install beware will not give refund support did not know there were 15 setup actions. setup error caused website to be shut down 3 days while i figured out fix and support said it wasnt their problem. i would give negative 5 star if i could. $600 loss and shopify credit refused refund that any other card would have graanted

Two days worked then no login. The verification is not being sent to the email. How can the first and foremost task of a user be problematic? No one tests this section of the app?

O Klavyio é uma plataforma super intuitiva, super emersiva e com imensas opções para reter clientes! Recomendo 1000%

If you want a single powerful tool to help you with email marketing that is easy to use, has a strong customer segmentation feature, detailed analytics, and much more, you wont regret getting Klaviyo. :)

I contacted the customer service team because I kept getting error messages inside of my account and I let them know that I canceled the subscription back in 2023, and had actively not been using the subscription since 2024 which was verifiable and their campaigns. They REFUSED to give me my money back and mentioned in an email “ although you canceled your subscription, there is a back end that doesn’t allow you to fully cancel it without our approval”. Basically agreeing that I canceled my subscription but HAVE been charged for the last two years without any usage of the app but even if you have and showed proof of cancellation, “they have the last say”. Definitely do NOT recommend them

Klaviyo is a powerful, intuitive, and comprehensive platform for email marketing and automation. The customer support is fast, knowledgeable, and genuinely helpful — a true partner for growing your business smartly and efficiently.

Klaviyo is likely the best email-focused CRM available today. If you aren't tech-savvy then you will struggle to use it. It is a deeply complex, and deeply powerful, software. Your business will benefit massively, but only if you dedicate an employee time to understand and use it well. They do, sadly, use generative AI. If they committed to ditching generative AI, as all companies should, then they would get 5 stars.

Klaviyo partners great with Shopify. They make it easy to create professional pop-ups and landing pages, which helps you add customers to your email list.

Very sketchy pricing. My $500 plan jumped to $950. We are chargebacking as they refused to work with us even though it was their systems issue.
