Klaviyo: Email Marketing & SMS

I've tried a bunch of these services so far and there is no question that Klaviyo is the most polished and most thoughtfully designed. The targeting granularity is impressive and easy to turn into actionable email flows. Loving it so far.

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.

Klaviyo is by far my preferred choice of email marketing service, and believe me, I have used most if not all of them. They provide pretty much the same services as others, but they do it through a better UI/UX and features that make sending emails out much easier. What really sets them apart is their customer service. I have spoken to a sales rep and technical support on their team over the phone. And they have been great to deal with every time.

Have not yet had too much experience with this app but after spending hours researching and trying out different solutions, Klaviyo seemed to be the right choice for me. Awesome templates for customer emails and extremely easy to use. I highly recommend this app to all.

Very easy to use and very helpful for a company just starting or a already established company

Klaviyo is really the best email platform out there I've tried others and I always come back. They're platform is very easy to use and the over all email aesthetic is great

I love Klaviyo and I especially love the personal service they provide. Highly recommend if you are serious about your email marketing.

Loving this app. Easy to use and tons of options for email campaigns. Just spent the last hour playing with the app, creating a campaign and sent it off.

Updated: 5/23 We have now been using Klaviyo for almost 4 years and we would still give them 5 stars. It is the best marketing investment we make every month. I do feel and understand the frustration with their support. Fortunately, we have not had much need to contact them. In our 4 years, we have only had to use technical support once and we were able to get the issue resolved in less than an hour. I do wish they had a "real time" support option beyond chat. When you have a problem, you want to get an answer asap, not have to guess as to when you might hear from them. We migrated to Klaviyo after the Shopify-Mailchimp dust-up last spring. We have been using Klaviyo for 15 months now and we are very happy with the app. While a bit pricier then some out there, we have found the campaign and flow tools to pay for themselves very quickly. In the past 12 months, Klaviyo campaigns and flows have delivered $21K (about 20% of total rev) in sales to our store -- and we don't even run a campaign every month. We made the investment to attend Klaviyo:BOS last fall, their user conference. One of the best user conferences out there, in our opinion. We learned a ton from Klaviyo and many other Shopify store owners.

Can I give it 6 stars?
Wow... I've been looking and spending money on other software, but this is just Amazing... The people at Klavio really understand what it means to be a Shopify store owner.
