Their form stopped to shop up without notice as I experience unmatching data analytics between how many customer left an empty cart and then indeed a form should be shown up. On top, I understand perfectly provide a payment tier for fast support but eliminate it as a way to resolve something that seems due to their feature not working, I think isn't the best experience. That's why I am proving 1 star. P.S the answer litterly show the Klaviyo did not understand that they do have a bug into cart detecting form as it is not shown at all to people thus let me loose many many people to signup.

Ellie was awesome in helping me navigate through installation challenges. Super prompt in helping me through the process.

Makes sharing new products SO easy, seamlessly integrates with Shopify, and adds revenue while you sleep when you set up flows. SO amazing! Klaviyo is a business game changer.

Great customer service and an awesome platform. They're always looking to improve the functionality and features of their site.

Klaviyo has so many incredible features and is user friendly. If you need advice they're always available to assist. Highly recommend.

Karen en Paola helped me setting up the right flows with the right metrics. They gave me detailed information and were very helpful.

Perfect infrastructure for marketing automation, improving conversion rate and maintaining customer loyalty. It is highly recommended!

Annoying buggy, strange logic rules, things sometimes work and sometimes don't, the most un-user friendly app on earth, I would switch from this in a second if I didn't have a hundred flows already programmed. Awful app.

Klaviyo impressed me with their exceptional customer service. When I encountered an unexpected issue, their support team responded with empathy and efficiency. They listened carefully, explained clearly, and went above and beyond to find a fair solution. While their platform has advanced features that new users should familiarize themselves with, Klaviyo proves they genuinely value customer satisfaction. They're willing to work through challenges and make exceptions when needed. For email marketing needs, Klaviyo shows they're a company that truly stands behind their service and prioritizes positive user experiences.

Great product that’s boosting my revenue. It mangles it a breeze and it’s the best my emails have ever looked!

They've already started increasing the price on us, despite the fact that we are still learning the system and have hardly sent any emails. I'm not seeing value for money yet. The built in shopify emailing system was adequate for us.

Very Well Managing App For All types of businesses. Its Auto import option is good working facility. i like this very much, as t is a very reasonable by rates also.

Its a large learning curve to become excellent at using, but i minor curve to get started and active. Klaviyo email flows brought in hundreds to my bottom line at a fraction of the cost for ads! I love it!

My store launch is being delayed because I want to ensure that the leads from paid advertisements will convert, so I need a solid email flow set up first. Unfortunately, I've encountered several issues with Klaviyo. First, I couldn’t upload my own fonts. I followed Klaviyo's suggestion to use the inspect tool to find the font code and upload its link, but it didn’t work. Although my domain and Shopify are connected successfully, I keep receiving errors when trying to publish a flow, stating it’s not synced to my store. I tested some cart abandonment flows using different accounts and waiting long periods, but no emails were sent, not even for test orders. When emails are sent successfully, they often end up in spam. Additionally, I’m forced to have my address in the footer of emails, which is problematic for a home-based business. Klaviyo also places a branding watermark on every email or pop-up, requiring an upgrade to a $20 plan to remove it. While I plan to upgrade once everything works smoothly to ensure my brand looks professional, the numerous errors and lack of support make it difficult to trust Klaviyo. I’ve spent two full business days trying to get it to work without genuine support. When someone finally responded today, they only addressed one error and didn’t provide a solution. It seems that without a higher-end plan, Klaviyo doesn’t offer much support. Larger companies receive weekly demos, but small startups are left struggling. Edit: They say that "double opt in" is optional but even if you uncheck it, they still wont add any email to your list that doesnt confirm a double opt in. Not only that, but they don't work with any intergration that is not on klaviyo, any sign ups from pop ups from other apps wont be added to klaviyos email list unless they specifically were added by a klaviyo native pop up. How frustrating, I've had my last straw. I'm out. Update: I've struggled installing, uninstalling, doing test emails etc for 3 days. Did they help or respond to my help requests? No. I saw a "klaviyotest" email subscribe to my list but never followed up on my request, which means they do see my requests but don't bother to help. If you're a start up, don't even waste your time here. They only care about big companeis and will kiss the ground they walk on being the one to spam those companies every two days begging them to use their platform. (a witness from both sides).

Usamos klaviyo desde 2021 en nuestro ecommerce y la experiencia no puede ser mejor. Y sobre todo, el servicio de soporte es realmente de los mejores que hay en el mercado de las apps. Porque cuando hemos tenido algún problema importante, han estado ayudando hasta resolverlo 24/7. Son conscientes de la importancia que tiene para cualquier empresa (grande o pequeña) que todo funcione correctamente.

While a bit more complicated to use than other email software systems, once Klaviyo is set up it runs beautifully! I will never go back to using software that isn't seamlessly integrated with Shopify!

The best email marketing platforms around. There is a learning curve, but they have loads of resources. Whatever I ask if it can do-it's always a yes.

Hello, I have been using Klaviyo for about 5 years. I also, love how Klaviyo has many different options for us wanting to be creative and attractive to our customers. Like that Klaviyo is concerned about what is concerning us as Business owners. Thank you, @KarlontyLWallace Pawsative Partnerships LLC

I had been hesitant to start using Klaviyo for quite some time - because it's considerably more expensive than other email services - but the first few email campaigns I sent out - to targeted audience - I got much more return than with the other email services. I am still trying to figure out how to set up the proper automations and flows - and landing pages.

The best email ESP I've used over the past 8 years in this industry. The offering creates ease, and a strong ROI. But the support is also fast and satisfactory.
