take forever to respond to support. I don't recommend to anyone. The email marketing machine is good but I always have doubts and they take 12 hours to answer me


Worst experience with this app. Not working and completely useless support. Im definitely not using it again !!


I have worked with multiple ESPs (email service providers) over the years and can tell you that Klaviyo is #1 at what they do--especially for their general audience (DTC/eComm). I will say, I've noticed reviews comparing other tools that offer the "same functionality" but there is a probable chance that these individuals are lacking a robust email marketing strategy to truly back those claims. You might be inclined to start with a very simple/handles-the-basics-type tool that offers free or competitive monthly costs. It's not worth it. Having to migrate and reframe your processes after the fact is not with it. I can tell you first hand that if you are ever planning to have or currently have the need for HIGHLY personalized automations, detailed segmenting, transactional emails, SEAMLESS integrations with a majority of your tech stack (returns, reviews, outside forms/popups, customer service tools like gorgias, etc.) then Klaviyo is far more established and advanced than a majority of their competitors. This product is easy to use (great for if you're new to email marketing) and simple to navigate when looking for something specific, but also robust enough to handle large lists/segmentations, persistent strategies, and detailed segmentation/personalization. Like any product, there is always room for improvement. For example, I wish I could split flows by if someone replied to an email (generally would love a reply tracking feature), but everything their tool is capable of FAR outweighs what they lack in these small, specific use cases. With Klaviyo, I feel confident that my emails will deliver, that they will deliver with the design I intended, maintain my credibility, and that I will be able to review the data to my needs in order to improve performance over time. I love the custom fields, simple API functionality, and being able to market to my customers authentically. I highly recommend it to anyone using Shopify and looking for the best, affordable ESP.
