User friendly and easy setup. Received guidance with a devoted team member has allowed for a seamless integration. Highly recommended.

Love how deep the integration of Klaviyo with Shopify goes. It makes triggering emails based on customers' shopping behavior more robust and personalized. I rely on Klaviyo heavily to understand our customers as a lot of Shopify data is fed into Klaviyo and it is really easy to use Klaviyo to get analytics. It also helps that Klaviyo has similar deep integration with many other platforms.

The interface and features are really impressive, so too the pricing promoted with the app-store. Once you are using it and your member numbers get over a few thousand, the costs skyrocket. Then if you uninstall it, beware. The pop-up windows for my newsletter sign-up remain. Shopify could not assist and referred me to Klayvio. This problem is still yet to be resolved and creating a horrible user experience. I think if someone uninstalls it should be a clear and clean removal and not this level of entanglement and impact on users. I regret signing up in the first place.

Klaviyo is a robust email marketing platform tailored for eCommerce businesses. It excels in delivering personalized email campaigns, thanks to its deep integration with eCommerce platforms like Shopify and WooCommerce.

If you ever get hacked, do not expect the customer support to help you. I have been using Klaviyo since 2021. Recently my account was hacked and after numerous emails to customer support, I have not received any help, other than them telling me that my account is not associated with the email I'm trying to use for my login. DUH ! That's the whole problem. It was changed. I will now have to uninstall this app, lose thousands of my customers emails, which I built up for the last eight years, as well as tell my bank to block these people from taking money out of my account. Thanks a lot.

If I could rate them a 0 I would. The process began great, i followed the steps to set up Klaviyo, and in the process accidentally selected to add the shipping banner at the top of my website. Once I was in the app I tried to remove the banner with no luck. I looked through all the settings, but as a first timer who's never used this app I had no idea what I was doing. I tried to contact customer service with no luck. There is no live chat with help and NO ONE answers the phone. I combed through the website and found nothing about sales banners or how to remove the one added. So I unintegrated the store, and it removed everything EXCEPT the shipping banner. The app is unintegrated and uninstalled and I am STUCK with a shipping banner for free shipping that I NEVER wanted in the first place. Called customer service 8 times and no one answered, the call hung up on me every time. I now have to go hire a coder to remove the banner. I am super unhappy. I run a business, and my client now has a delay on their website. Absolutely Unacceptable.

I've been using Klaviyo for four years, and it has become a vital extension of my business, nardurna.com. The platform's robust features and seamless integration with my e-commerce site have been essential in helping me connect with my audience in meaningful ways. The ability to segment my audience and tailor my messaging has significantly improved my customer engagement and overall sales. Klaviyo's support team has also been incredibly responsive and helpful whenever I've needed assistance. I also want to thank Klaviyo for inviting me to an exclusive event earlier this year in Byron Bay—an experience that further solidified my appreciation for the platform and its community. It's an indispensable tool that has played a key role in the growth of my business. Ryhia

We've been using Klaviyo for a few years, and it has significantly enhanced our marketing strategy, especially with its seamless integration with Shopify. The email campaigns and automation flows are user-friendly and offer great customization, allowing us to create targeted and professional-looking emails with ease. Although we haven't used the SMS feature due to the alcohol regulations, the email tools alone have proven invaluable in boosting customer engagement and driving sales.

Great product but support since the IPO has dropped, the support teams aren't given any powers to do anything so you can wait weeks/months from connected departments. If you need/think you might need to move quickly then choose another vendor.

Klaviyo is the best marketing automation system in my opinion for marketing and building a loyal customer base. Very flexible and convenient, works great with Shopify and other integrations. Highly recommend with over 5 years of experience.

Took about 2 months to try and get Klaviyo to integrate with Shopify tags with lots of back and forth between support who weren't able to assist me properly, rather just sending me a link to an article. We were also overcharged for 3 months and still yet to receive our money back. Set up with Omnisend and immediately the integrations of profile data, segmentation and shopify tags were there without me even paying for anything.

This app is producing sales for us. But need to learn to develop flow campaigns which can be a learning curve challenge. But if I can do it, you can do it.

I use Klaviyo for probably 10 clients at this point and it is one of the best email platforms I've ever used. Their customer support is available to chat during working hours and they're super helpful. The platform has so many incredible capabilities. I really can't imagine wanting anything more from an email marketing app.

Jono was exceptional it was my first time contacting Klaviyo and he went above and beyond. It was a very technical question that was resolved in minutes so thank you again!

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.
