Best Email system for E-Commerce Shopify Store owners

What do you like best? The Klaviyo integration is so tight - you will think it is part of shopify but on steriods What do you dislike?

Best Email Automation for Sales!

What do you like best? I've used other email marketing crms and unlike Klaviyo they don't have an user friendly interface. I love how easy it is to jump into Klaviyo and get started out the box. The emails look great and are very easy to build. They've thought of a lot of functionality that leads to sales. Their browse abandonment automation is amazing! The ability to easily segment customers is what I believe differentiates them the most from other CRMS. When I started email, was barely ...

Its so easy to use

What do you like best? Integration is easy; Klaviyo just integrates with Shopify and other apps without any problems or issues. The email templates are easy to use, look great and are converting well for us. Open rates are better than our previous platform. What do you dislike? You can't embed video in emails, only GIFs which click through to the video. Not sure whether this impacts on open rates and conversions; we can't AB test because we can't use video!

What do you like best? Klaviyo allows us to initiate real conversations with customers and prospects, based on what they're actually doing. People actually want to hear from us now that Klaviyo has given us the ability to personalise messages. What do you dislike? There is very little I dislike about Klaviyo. If pressed for an answer, the only thing I could say is that I do need to doublecheck my logic when it comes to automated flows. But that comes down to the human, not the ...

Hands down the best marketing tool your online business will use.

What do you like best? I love the automation that Klayvio offers. Our automatic flows make us money without us having to do anything at all. If we didn't even send a single email blast, the flows alone pay for its self. I also love the ease of setting up audiences for campaigns. What do you dislike? I don't have any major qualms to bring up, but I guess the only thing would be that we have to pay for a lot of our audience that we don't use. It's rare that we blast out to as many ...

Great software

What do you like best? It is very flexible and does everything we need it to do. There is no question that the features set you will require will be part of it. What do you dislike? Not much to be honest. The only thing is that they don't work on your Shopify store directly but they will always guide you on how things need to be done. Recommendations to others considering the product: Use all the features that they provide What problems are you solving with the product? ...

Superior Product and continues to get better!

What do you like best? Intuitive design leads you through create email automated flows in a fun and simple way! I love seeing so much information about customer behavior in their profile. Klaviyo continues to release new features and i'm really excited to use the best-deliverability-predictor tool. What do you dislike? They are very strict on hard bounce rates, unsubscribe rates, and spam complaint rates (I refer to this as Klaviyo jail, ha ha). So, be very sure your lists are ...
