I have had great experience on Klaviyo. Fast support. Customized emails and templates. Love this app. Don't hesitate to use. Make sure all your templates and settings are correct before you launch. Builds revenue - you would not think so - but so many people shop off emails.

This app has been amazing - the way everything is so customisable and you can do so much with your existing subscribers list is so helpful. The online support is amazing and so fast with getting on the online chat to assist. The forums are also helpful along with the step by step guides. Cannot recommend this app more!

I've enjoyed using Klaviyo. I have seen growth in our sales using it. They also do weekly classes about using their platform which has been very helpful.

Probably the most user friendly esp there is. if you are an ecom brand owner, and not utilizing emails, consider Klaviyo. has free resources to get you started and the aftersales support is superb.

I left Klaviyo after a month or so about a year ago for no reason other than I already had a bunch of subscribers with another service. But I recently smartened up and went back to Klaviyo. The support alone blows most away, but the entire system is so powerful. I now realize it's foolish running a business through Shopify without it.
