"Great email with terrible analytics"
What do you like best about Klaviyo?

Email flows work like a charm. It is highly customizable and great in the means of creating rules and segmentation. Mail builder is easy to use and allows enough customization to avoid HTML coding

What do you dislike about Klaviyo?

Terrible internal analytics. It really sucks - GA and results in Klaviyo dashboard are usually at least twice different. There is no way to work with a single account with two Shopify stores that share database. We have to make it through Zapier and still need to do some manual checks every week to keep the track

What problems is Klaviyo solving and how is that benefiting you?

Moved from Mailchimp on recommendation and Klaviyo turned to be an amazing tool for e-commerce email flows.

"Easy Email Templates and Flows"
What do you like best about Klaviyo?

The flows are pretty straight forward and easy to set up but you can make them more complicated if you need to. There is a drag and drop builder, A/B testing, and discount codes, and website popups/email collection forms. It integrates well with Shopify and other e-commerce platforms.

What do you dislike about Klaviyo?

There could be more integrations or more complex metrics. Wish they had gamified popups like sprin the wheel option. You can't connect it to Facebook Messanger or have push notifications like some CRS services. There could be more automation offers. Issues connecting with Tableu.

What problems is Klaviyo solving and how is that benefiting you?

Customer signups on the site, education with education flows and offers, winback campaigns offering discounts, and staying in contact with our customers.

"Great program to start your customer lifecycle, albeit pricey"
What do you like best about Klaviyo?

The ability to quickly and easily collaborate with my team and all of our various skillsets to get a customer lifecycle up and running was huge for us.

What do you dislike about Klaviyo?

Pricey. Wish there was maybe a live edit feature when working on flows or campaigns so that we can collaborate remotely.

What problems is Klaviyo solving and how is that benefiting you?

A clear and concise customer journey that is highly mobile and adjustable so that we can fine tune at any given moment.

"Thoughtful, covers email marketing basics, excited to see improvements"
What do you like best about Klaviyo?

Simple interface and it's easy to get started. There's a lot of pre-built options to help new customers and novice email marketers get started.

What do you dislike about Klaviyo?

Segmentation feels a little slow. There are some nice-to-haves missing: quickly copying elements of segmentation, viewing outputs, checking counts. Would also be nice to have workflows that show you how many people are waiting in each step without clicking into them (at a high level). I also wish there were ways to see revision history when multiple accounts are in-use. I'm the only email marketer on my team currently, but as we expand, this will be crucial for keeping things clean.

What problems is Klaviyo solving and how is that benefiting you?

Running our email program without constant issues from the former ESP.

email frequency preference is something i'm working on now. benefits have been being able to segment and be able to target specific groups.

"Easy Customer Service "
What do you like best about Klaviyo?

The live chat available during business hours is helpful.

What do you dislike about Klaviyo?

There could be more design features. Many things have to be done in source (coding) which most people are not familiar with.

A/B variations allow us to increase email open rates. Flows allow us to increase the sales from our website.

"Magento Integration Review"
What do you like best about Klaviyo?

How well it integrates the users from Magento into Klaviyo. You can see how users interact with your site, what pages they visited, and what campaign they came from. A bonus is how it can create and update Facebook audiences, based on lists.

What do you dislike about Klaviyo?

That it can not do unique coupon codes for each user in Magento. This feature is highly needed for Magento. I can put static codes, but the issue is that it gets shared..

What problems is Klaviyo solving and how is that benefiting you?

Sending out welcome flows and campaign, for different user groups in Magento. Depending on the user group in Magento, I can set up unique flows for them.

What do you dislike about Klaviyo?

Support team being based in USA. And the Magento integration being absolutely dreadful.

What problems is Klaviyo solving and how is that benefiting you?

Reduces dev time and resource, speeds up certain processes and allowed us to scale the email and CRM function rapidly.

"Great for Price, Advanced Automation but Unreliable analytics"
What do you like best about Klaviyo?

Ability to create dynamic segments and flows

What do you dislike about Klaviyo?

Unreliable analytics. They never line up with Google Analytics. Klaviyo needs to work to have a more solid integration with Google Analytics. They also don't have a reliable chat support.

What problems is Klaviyo solving and how is that benefiting you?

We're able to build out our automated series exponentially with Klaviyo.

"Similar to a lot of other email platforms"
What do you like best about Klaviyo?

IMO Klaviyo is really similar to a lot of other email platforms. One plus to it, though, is the flow system you can set up for emails. (But a downside to that is that you can't edit the "incoming" manner after originally setting it up)

What do you dislike about Klaviyo?

Lots of limitations (see likes), but their support is responsive and open to feedback.

"Great data but expensive"
What do you like best about Klaviyo?

Great data insights compiled from campaigns. If you are going to invest the time into email then this is a great tool to have.

What do you dislike about Klaviyo?

Double the price of platforms like mailchimp. You need to be fully committed to email if you want to make the price worth it.

What problems is Klaviyo solving and how is that benefiting you?

The data available from campaigns makes it easy to be more strategic.

"Big Jump from MailChimp"
What do you like best about Klaviyo?

The platform has a lot more features than MailChimp but still isn't super robust. I like the ease of use and the options to use a lot of advanced automated flows. A/B testing is a lot better over MailChimp as well and have more options to test.

What do you dislike about Klaviyo?

Some of the anaytics aren't all the way correct when looking at the Automation Flows. In order to see any data of past flows in the main dashboard you have to have that flow active. Really makes reporting time consuming as you have to go into that individual flow campaign variant to see what the numbers are. A/B testing has some great options but still lacks some options in testing automations.

What problems is Klaviyo solving and how is that benefiting you?

The business problem we are solving by using Klaviyo is having a smart email marketing platform that helps optimize campaigns through automation and a/b testing.

"Expensive and not many options"
What do you like best about Klaviyo?

The possibility to design the emails for desktop and mobile (even though it makes the emails weigh too much).

What do you dislike about Klaviyo?

We have lots of issues with the plugin (Magento), and there are no web automations.

What problems is Klaviyo solving and how is that benefiting you?

Sending newsletters and flows.
