Responsive customer support and valuable educational resources further enhance the user experience, making it a key tool for e-commerce growth through targeted, data-driven campaigns.

Klaviyo has been a game-changer for our Shopify store!

Setting it up was seamless, and the integration with Shopify works perfectly. I love how easy it is to create professional-looking email campaigns with their drag-and-drop editor, while still having the flexibility to customize with advanced features.

The automation flows (like abandoned cart, welcome series, and post-purchase follow-ups) run smoothly and save us so much time. On top of that, the customer segmentation tools are extremely powerful — we’re able to send highly targeted campaigns that actually convert.

Since switching to Klaviyo, we’ve seen a clear improvement in both engagement and sales. If you’re running a Shopify store and want to take your email marketing to the next level, I highly recommend it.

It's really awesome to hear that you've seen so much success since moving to Klaviyo, and that setup has been so easy! Thank you for the 5 star review!

Klaviyo is by far the best email marketing programme out there. Knocks the spots of some other well-known offerings that I have tried. They have taken a complicated operation and made it simple for people with no prior experience, and offer exceptional training and support. I recommend Klaviyo to everyone and find it to be one of the most useful tools in my box for increasing customer loyalty and conversions.

Edited October 15, 2025

My issue was resolved, but I experienced over 500 random bot sign-ups through Klaviyo, which forced me to spend around an extra $100 to cover the additional charges. After being billed for three months, I requested either a refund or a discount, as the issue wasn’t my fault — but my request was declined. As a loyal customer, I found this quite disappointing and lacking any gesture of goodwill.

Update: I have been credited the amount by their helpful support staff, I have changed to 5 stars :)
