I love Klaviyo! The product is amazing and the support is incredible. They keep adding valuable features that make the product even better. They've helped me so many times with sometimes complicated coding work and they've never been rude once! I'd recommend Klaviyo to anyone!

Best email marketing app there is. Use it daily for so many things. Highly recommend over any other email marketing software.

We have tried at least 2 other email marketing platforms and I have to say, compared to Klaviyo, it felt like they were in the dark ages of Web 1.0. They were clunky, unintuitive, and their templates were terrible. Klaviyo gives you automated marketing features like segments and flows, that can send sequences based on triggers to ensure the right emails get to the right people (newsletter subscribers, post purchase follow ups, abandoned carts, just to name a few.) Basically Klaviyo handles complexity without getting complicated (two related but very different concepts!) Seriously I thought it was a bit intimidating at first - but once I dove in, it is unbelievably intuitive to work with and so straightforward to get started with. Their Help/Support documentation is awesome, and they have an article for every single issue or feature that I needed to learn more about (super easy to search their site or Google to find the support material you need, because their content is so well organized.) I have run into multiple other Shopify brand owners and marketers that have echoed the very same sentiment (which helped reaffirm it for me) that Klaviyo is the current winner in the email marketing space and especially in the realm of Shopify and ecommerce. Definitely recommend!

Excellent app, very smooth and very useful. I'm a first time web store owner and created great emails with this app very quickly. Give it a shot.

I use this app for all of my email marketing. I really enjoy its ease of use and powerful algorithms. I wish it was a bit cheaper but they do good work.

One of the best features is that Klaviyo auto imports your theme's colors and font settings. Absolutely a great out of the box experience!

A dreadful, user-unfriendly app. It seems like you need a degree in computer science just to navigate the basics.

For example, I wanted to create header links in the welcome series template but no obvious option to do so anywhere. So I saved that email into templates, and again, no apparent way of adding header links in the header bar.

I thought it would be very simple to do this but apparently not. On top of that there is NO support for newcomers, they just robotically refer you to irrelevant articles that don't answer the question. I also heard that when you do have a paid plan for support that some of the subscribers are having lots of issues with it.

A nasty app, stay away.

Thanks for your comments and we're sorry you're having trouble with header links.

When you click on the header bar in your email template, a menu will show up on the left side of your screen. In the content section, you can add links for the header bar and set the font, color, size, etc.

Hope that helps!

Here is a more complete guide to using the template editor. https://help.klaviyo.com/hc/en-us/articles/4407911841435

Terrible support. They do the bare minimum to help their users and will make you use one of their partner developers if something isn't working. Any other app would try to help you with a problem you are having with their app but not Klaviyo.

I've used a number of e-mail service providers before. Klaviyo is by far the best. The segmentation ability is so key for us in being able to separate our in-store and online customers.
