"A great solution for Shopify stores!"
What do you like best about Klaviyo?

One of my favorite things about Klaviyo is just how easy it is to use. They have done a great job making it user friendly and at the same time it has many powerful features. I love using it for abandoned cart follow ups.

What do you dislike about Klaviyo?

There's not really anything I don't like in terms of the features Klaviyo offers. It would be nice if they could bring the pricing down some. But overall it's a great ESP and is the best in it's class for what it does.

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

We use it for abandoned cart follow ups and keeping in touch with our customers. It's much more powerful than some of the other solutions on the market. I would highly recommend them for SMB's.

"Simply the best ESP out there"
What do you like best about Klaviyo?

Ease of use, integrations, and great data/analytics. Klaviyo is the best tool I've used for email (and I've used just about every ESP available). In addition to the features, customer support is top-notch.

What do you dislike about Klaviyo?

Honestly, I'm struggling to find something I DON'T like about Klaviyo. 9% of the time, I recommend Klaviyo as the go-to ESP for my clients. No complaints coming from me!

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

We use Klaviyo for email and SMS marketing. I particularly like how I can keep both services under one roof, and can look at that data (as well as e-commerce and activity data) in one place.

Our numbers looked off after switching to a new e-commerce platform but was quickly resolved!

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

The API is very in-development and some features are only available via the web UI.

"Highly recommend for e-comm companies on Shopify"
What do you like best about Klaviyo?

The shopify integration is the best I have seen in the ESP space. Klaviyo is intuitive, easy-to-use and provides great metrics to help optimize performance.

What do you dislike about Klaviyo?

The UI looks a little bit outdated. It is also not the greatest for running experiments.

"Best all-in-one owned marketing tool"
What do you like best about Klaviyo?

Klaviyo makes it easy to pull in custom events to construct your retention marketing to match your customer journey. Every industry has its own buyer journey, and Klaviyo makes creating a great customer experience easy.

What do you dislike about Klaviyo?

Would love to be able to connect different flows together and add more flow actions into the journey builder.

"Great features, great support team, and a great value."
What do you like best about Klaviyo?

It has excellent integration with our other Marketing tools and Ecommercoe website. Our account manager is super helpful too.

What do you dislike about Klaviyo?

The technical documentation for custom integration API's isn't great. Creating custom transactional emails to be triggered elsewhere isn't great, either.

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

It's easier to build segments for more personalized, less "One Size Fits All" emails.

"Klaviyo Is An Essential Tool For All Marketing Teams"
What do you like best about Klaviyo?

Klaviyo is a very complete platform and makes email marketing so much easier than some of the competition. I also love the customer support and strategist teams. They are very fast at replying and ready to help solve all issues.

What do you dislike about Klaviyo?

Klaviyo has good reporting, but I wish their segment builder had more options. Also, there should be a way to measure segment growth and decline.

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

Klaviyo is helping us communicate promotions and news to our most valuable customers. This helps us bring in more revenue month after month.

"User Friendly"
What do you like best about Klaviyo?

Klaviyo offers really nice live sessions on their website to walk you through anything you might need help on, but even the platform itself lays out analytics and helpful tips. It's great to have email and SMS in one place from a marketing perspective. Klaviyo is constantly adding new helpful features with benchmarks, analytics, design, etc. and their support team is always there to help!

What do you dislike about Klaviyo?

Sometimes there is the occasional glitch, which makes me lose my progress in an email template or lose data for the analytics. It can be frustrating to start over or be missing bits and pieces. With SMS, it can be challenging to decipher the required components to SMS are, and there is always the fear that you're doing something wrong - especially for us as we have both US based lists and UK/rest of world. It would be great if Klaviyo had a more clear and obvious layout for opt-out/opt-in and all the required fields. The live sessions have helped me understand those requirements better.

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

Hugely important to be segmenting and targeting people on a more personal level! Klaviyo is great for this. We use Klaviyo for building several segments and sending them messaging that applies to them.

"Easy and Intuitive!"
What do you like best about Klaviyo?

I love that the software itself is easy (once you know it) to use but nearly all software apps we require for marketing are able to integrate with it. Making for a MUCH easier work flow process.

What do you dislike about Klaviyo?

Intially learning the platform was a bit tricky. Building out segments felt like a riddle at first but as I researched more, watched videos, looked up articles, I started to get faster and smarter at utilizing what I had at my fingertips.

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

At the minute, Klaviyo is the best way to keep in touch with our customer base. SMS can sometimes feel invasive (don't want to oversend) but it always feels like I can send to our customers via email.

"Powerful and Intuitive"
What do you like best about Klaviyo?

The segmentation tool is phenomenal given how many variables you can use to create specific lists of people for campaigns, we have even used these lists outside of klaviyo for integration with other platforms such as Attentive and doing custom loyalty type incentives!

What do you dislike about Klaviyo?

I don't know that there are any limitations to klaviyo that I have come cross and haven't been able to solve one way or another. I do wish there was an easier method to setting up a dedicated click tracking domain, particularly with shopify, but we were able to accomplish our needs by supplementing with cloudflare.

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

fully utilizing the features given for audience segmentation to gain the right list of users we want to target for specific campaigns, having the verbose flow builder for automated messaging, and an easy-to-use email template builder that we can create and schedule ahead of time. All of this frees up an enormous amount of time and resources for our team to focus elsewhere.

"Very user friendly platform"
What do you like best about Klaviyo?

Very user friendly. The drag and drop feature makes it very easy to design our own emails with minimal graphic design experience. Also love how easy it is to create an automated flow.

What do you dislike about Klaviyo?

I wish their Back in stock flow was easier to set up. We are not able to send back in stock notifications for specific sizes (child sku), it's only at the high level (Parent sku).

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

"Great CRM Experience"
What do you like best about Klaviyo?

I will be honest, we've moved onto Braze but for the years I used Klaviyo, I think it was great. The automated flows, ease of use, segmentation and data ingestion was great.

What do you dislike about Klaviyo?

The ability to get super granular with the customizations and ability to do a ML based canvas approach to campaigns.. That was pretty much it.

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

As I mentioned before, Klaviyo is great for automations, data ingestion/management/segmentation, and relative ease of use. It is a supercharged step up from mailchimp and two companies under out umbrella still use it.

"In depth-analytics make this platform top-tier"
What do you like best about Klaviyo?

Analytics and reporting, ease of editing, and we very specifically like the feature to suggest products to our customers based on behavior.

What do you dislike about Klaviyo?

I still create blocks in a design program to import and use. I do wish there was a way to create a "template" and drop images specifically formatted into. I understand that is cumbersome, and no one else offers this feature, either.

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

Personalized recommendations to reach customers who have previously engaged. This, in turn, creates higher conversions that we would have otherwise.

"Almost everything you need to communicate with customers in your applications and marketing"
What do you like best about Klaviyo?

I like that Klayvio provides both transactional and marketing emails and texts for our customer communications. It makes things easy as a developer. You integrate the events into your app and then the marketing team and others can use the interface to create any flow they want to communicate with the customer. There is a lot of flexibility. Also having profiles with all the communication in one place is critical to providing customers with a great experience throughout our application.

What do you dislike about Klaviyo?

The only downside right now is that the service doesn't include desktop notifications. If it had that then this would be the only communication service you would need for your app.

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

Klayvio solves our need for marketing and application notification automation. Using Klavyio for all this makes it easy on the team to integrate as well as the team to market and create automated flows of what's sent and when.

Klavioy is a great tool that is intuitive, with a ton of resources to get you started. The Klaviyo academy is a great way to get started, and the customer service is very helpful. Anytime my team has a new strategy or idea we want to test, we get useful insights from the Klaviyo team and resources.

"A terrific choice for SMBs to improve their email strategy."
What do you like best about Klaviyo?

User interface is simple if you're familiar with CMS interfaces. Terrific options for extensibility with other services (Attentive, Shopify, etc). Great customer support.

What do you dislike about Klaviyo?

Some of the UI navigation is a little clunky. Analytics are available but require quite a bit of legwork in order to build the reports/dashboards that are ideal for your business.

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

Having a unified tool that works with our other tools in order to provide a consistent face to our brand, while maintaining a library of our own templates for use as well as the intuitive flow automations to allow for terrific remarketing, has allowed us to act as though we are a much larger organization, and focus our efforts on other tasks without needing to micromanage our email strategy.

Klaviyo is not just an email platform. It's a full marketing app that allows customer targeting in thoughtful ways to make their experience the best it can be.

What do you dislike about Klaviyo?

Klaviyo is a chunk of my monthly marketing budget but the analytics and Feedback I get from it allow me to justify the expense. Revenues are going up and my management are happy with the results Also would love to have a phone app to manage and perform basic tasks.
