I love Klaviyo. It has such powerful tagging, segmenting and flow work. I can break down customer lists any way I want to try different marketing options. Campsiteflags.com keeps our customers informed using Klaviyo.

The BEST Hands DOWN!!! I love using Klaviyo. I am using it for all my sites. And I think everyone should to.

This is a very clean, pretty easy to use, very full featured without being overwhelming, professional level app.

If you've got less than 250 subscribers and can use this for free then go for it.

If you've got a profitable store and you want to run effective, measurable, campaigns then yes, definitely try this.

If you're somewhere in between you may want to look elsewhere. It is expensive compared to some other options but we're finding the functionality and potential to get sales from customers well worth the cost.

The functionality is great but it's a shame the costs rack up as you get more subscribers. It would be good to have a better pricing structure for the store owner. https://www.katysboutique.co.uk

I love the automation this offers! I can set up my email flows and campaigns and not worry about it! I like the dashboard so I can get a glimpse of what has happened since my last login.

Pas mal comme appli :) je la test depuis un tout petit moment :) ça fait du bien mais je donnerais un autre avis quand je serais un peu ancien avec cette appli :)

Used to be good but now the emails they sent out during my campaigns keep getting bounced for no good reason - one of which is my personal email and another my friend’s email. Tried to send a campaign just to my email add and I don’t receive it at all. And no it’s not in my junk box either. Ridiculous if that’s the primary function of this app.

This is an excellent app! Better than some of the email marketing systems I use for my non-Shopify business. This is great for retargeting and it is really easy to use! Very happy to use this for my business.

Klaviyo is the app to use for all your email marketing, straight forward and easy to use. It give you real data to see how well your campaign is doing.

I use this app to assist with my email re-marketing campaigns. Better than most api's that claim the same benefits also comes with great drag and drop templates. You get up to 250 subscribers for free when you get above the allowed free account the benefit outweighs the cost. The support is also excellent and always responds promptly. One of the must have api for a e-commerce business. Klaviyo also integrates well with a lot of api's, the instructional videos are very well put together. Thank you to the team at Klaviyo, excellent product.
