Klaviyo has been a very helpful platform for managing our email marketing and customer engagement. The segmentation, automation flows, and reporting tools make it much easier to understand customer behavior and improve campaign performance.

What impressed me most is the quality of the customer service. The support team is professional, responsive, and always willing to provide clear guidance when we have questions. Their help makes the platform much easier to use, especially when optimizing flows, troubleshooting issues, or improving campaign strategy.

Overall, Klaviyo is a powerful and reliable tool, and the excellent customer support makes the experience even better. Highly recommended for businesses that want to build stronger customer relationships through email marketing.

What we love about Klaviyo, apart from being user-friendly and having great analytics, is that they regularly provide training to help us use the app more effectively. Highly recommended.

Klaviyo when used properly is a game changer - just make sure that you are sending emails that people actually want to open - dont only use email marketing to promore sales and specials.

We use Klaviyo app for more than 5 years and it did help us recover the carts left by sending a series of abandoned cart emails. Welcome email, post-purchase follow-up email, and other customised emails, all help us bring in sales and grow steadily. Thank you so much for Klaviyo app which keeps releasing new features !!

Everything just works - from popup to purchase
We run a premium dog care store in Bulgaria and Klaviyo has become the backbone of our email marketing. The Shopify integration synced our subscribers, orders and events flawlessly, in both directions. We built a welcome flow with a discount code, an abandoned checkout flow and a signup popup, all connected to the store data without a single technical issue.
What impressed us most: the level of control. Smart targeting rules for forms (scroll depth, exit intent, excluding existing subscribers and checkout pages), per-message Smart Sending settings, and clean sync settings that just make sense. Support for a non-English store (Bulgarian forms, emails and error messages) worked perfectly too.
If you are serious about turning store visitors into repeat customers, this is the tool. Five stars, well earned.

Klaviyo has been really easy to use for my store. The automations make a huge difference—especially the abandoned cart flow, which helps bring customers back without me doing anything. It’s a true set‑and‑forget system that saves me time so I can focus on other parts of the business.

Thank you so much for the 5 star review! It's awesome to hear that Klaviyo is playing such an important role in providing your customers with a great experience.

Klaviyo makes it so easy to set up and send campaigns. I know I am not even using all of the features that I should be and it has added "easy" additional revenue to my business.
