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.

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!
