It covers absolutley everything e mail - As the owner & not a tech geek I can easily "hop" in & see what the team are building / actioning with ease

They helped me instantly, they were quick to respond and knew exactly how to resolve the issue, Great customer service

We've used Klaviyo for the last 3 years for multiple Magento sites, but have just migrated one of those sites to Shopify. As expected from our experience with Klaviyo over the past 3 years, the process was silky smooth and when support was needed, it was fast and efficient. Thanks for all your help with our migration

Klaviyo provides excellent resources to help grow my business and I am happy with the progress we have made over the last few years. I would heartily recommend Klaviyo to you for your email/SMS needs. John M.

Klaviyo is by far the best ESP there is. I love all the complex functionality that allows for doing everything I want to do and more, the email and sms creation and automation, clear analytics, advanced segmentation capabilities, great Shopify integration for all kinds of order and product data use and triggers, and the way they work to make it as easy to use as possible.

Amazing!! Highly suggest using Klaviyo. It's one of the smartest CRM platforms out there. Customer support is truly incredible and can help you with any step of the way. If you have a Shopify account, you'll want to get Klaviyo for email marketing and SMS.

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).
