It's been great. I had one experience with customer support where I felt the person wasn't going to pass on valid feedback (open rates of the first email cut by half due to < 2 hour wait with FB sync). But other interactions with support were great and I also was able to connect with their product manager who promised to look into it. I felt they're a young and flexible team. Also laser focused on email and what email marketers need.

If you want flexibility in segmenting your drips (or flows as they call it) then you need to use Klaviyo. We were using Mailchimp and kept finding areas that made it time consuming, confusing, or just not built to have a flexible drip campaign where contacts receive emails based on rules. For example you can easily create a series of emails that are only sent to contacts that meet a specific criteria and do it all within one drip through a "workflow" like drag and drop builder. You can also sync up to your facebook leads and save money on Zapier which is what you need to use if with Mailchimp.

While Zapier immediately pulls in leads from Facebook, Klaviyo only syncs every 2 hours. A lead getting a welcome email right away is SUPER important, but this means they don't hear from us for some time and it's negatively impacted our first email open rates -- almost cut it in half.

Overall I've been very happy with Klaviyo and appreciate its focus on email marketing and SMS rather than trying to be the tool for everything.

I use Klaviyo for my email newsletter. It's been a smooth process overall. I've had no issues importing and managing lists and contacts and have been happy with its design capabilities, deliverability, and analytics.

As my list grows, I'm a little weary of the pricing for larger audiences, but that is only an issue I see down the line.

We use Klaviyo regularly and it's great for email automations and campaign sends. Email marketing is a must for any eCom business and Klaviyo does it well. The only downside is the cost. It's starting to get super expensive as our list grows.

I like the automations, triggers, and data. Love that it integrates with shopify.

The cost is starting to get out of control. Getting really expensive.

Poor, I wouldn't recommend Klaviyo over others that I have used (Active Campaign, Omnisend, Drip).

The Klaviyo application is very powerful, no doubt.

The UI for the automation flow filters are not intuitive and not well designed. Basic requirements for flows are unnecessarily difficult to implement. When you contact Klaviyo support, staff gives information that contradicts their published documentation and often don't actually give the correct advice at all, resulting going around in circles trying to get issues resolved. Klaviyo list management is also poor, and like some other platforms (seems to be a trend), Klaviyo gears the system towards pushing you to pay for more customer profiles than you actually need and then when you try to clean or remove profiles you have to go through manual processes, whereas Klaviyo could easily provide options to automate this, or at least NOT require manual CVS export/imports. I mean really Klaviyo it's 2022 people. The Klaviyo visual builder is buggy, even in their "NEW" builder there were bugs with things as basic as applying link colour styles at a global level. Generally also poor UI for the visual builder. Overall, it's almost like the Klaviyo designers tried to make the UI as clunky as possible, probably went to the same design school as the Mailchimp designers (which is equally terrible).

Migration and set up was long but relatively straightforward.

Drag and drop editor functionality was the best that I have seen on any platform especially with the customisations that you can do with variances in desktop and mobile versions.

We don't have a global view of all of our accounts. We do struggle to keep all 8 accounts up to the same standard as our main one.

Setup flows and integrating with another apps.

I can not send SMS to Germany. And the price a little bit high.

Klaviyo has my favorite email builder with drag and drop widgets that give you hundreds of options for layouts and graphic elements. You can also create global sections that can be used across different email templates.

I liked how easy it was to create sections with columns or nested elements within the drag-and-drop builder. There were very little layout restrictions and that made creating emails much more user-friendly and highly customizable.

Sometimes the fonts didn't always show in the email preview correctly.

Klaviyo has a ton of features built in to get your emails shows to the masses. I am not an email expert but I am able to figure it out.

I can get a little confused with the terms used for different areas of the software. They sound similar to me

The email marketing features are intuitive and easy to use. I've seen a noticeable increase in engagement and sales since I started using the segmentation and automation tools. Plus, it's easy to integrate with Shopify, so you can sync data and track performance.

The prices be relatively high compared to other email marketing platforms which can be tough for businesses with smaller budgets or newbies.

We are always looking for a way to showcase our products and so try different providers in an effort to grow and test our email management. The set up for Klaviyo was simple and easy, as was the creation and send process. I would recommend testing it, especially if you have a very visual product catalog, as the image captures are what impressed us most.

Sharp and crisp product images that look great delivered via email.

The initial trial offer should be longer to be able to test deliverability, open rate and conversion rates.

I love this i will still use it on my shopify store.

I would say the best app on email marketing.

I couldn't think of content to put sometimes. I wish this have articles or trivia through integration of chatgpt.

Besides cost, the biggest team our team wanted to get out of the ESP was email automation which you get built in with Klaviyo. We had some assistance with our agency to get on-boarded and build some additional flows but overall, there wasn't to much of a learning curve with building the emails. Their tables do not render nicely in Outlook though, which didn't have that issue before which is a bummer.

With our previous ESP, we had to pay extra for the automation that you would expect with your email service provider. With looking at bottom line, that is what lead us to research other ESPs, which lead us to Klaviyo. While there is a learning curve with any new program, this one wasn't to bad to get adjusted. I will say I do miss the dedicated account rep we had with previous ESP and the on-boarding specialist okay...our marketing agency helped with the on-boarding as it was heading into Q4 and they helped steer ship in right direction after first two emails had less then stellar open rates.

The features are there that you need from an ESP perspective. They even recently announced the introduction of SMS marketing within their platform which helps ROI tracking to be even better instead of having to rely on a 3rd party vendor and who takes credit between a SMS message or email message. While our email send total is actually higher than in Listrak, we do not have a dedicated account manager to meet with and discuss the account, what they see, suggestions on where to optimize, etc. It is much cheaper than Listrak and another ESP we looked at so you get what you pay for.

I have tried many email marketing providers (MailChimp, Sendlane etc) and found that Klaviyo offers the highest customer service, hands-on implementation, very detailed training and on-boarding. They also offer many pre-build email templates and flows that are customizable

Klaviyo's customer service and implementation team is outstanding! Nate walked us through the platform and shows us the dashboard, which was very helpful. After we signed up, we had 6 (1-hour) onboarding calls with an implementation specialist to make sure we set up everything correctly. They offer MANY pre-built email campaign templates and flows, so creating a full email strategy is very easy! Reporting and the dashboard is very user friendly. Connecting with Shopify only takes a minute.

We hope that the SMS marketing feature will integrate with Gorgias soon - Klaviyo confirmed that it is coming!

Great! Although I’m very critical of their UX, Klaviyo makes up for it in the number of features it offers. Also a great platform for agencies, as it has a lot of built in reporting features.

It has all the features that a seasoned marketer needs

The user experience can often be slow and laggy unless you have a high end computer with lots of RAM. Probably the only bad thing about Klaviyo.

I have only been using Klaviyo for 3 months and I only wish I had discovered it before. If you sell online through an e-commerce platform give it a try! You will not regret it!

I have nothing but good things to say about Klaviyo. It is filled with great features like no other email app I have seen before; it has a very friendly interface that makes email creation a breeze; excellent analytics and a very fair price. The other huge plus is their amazing customer service! They are on their toes waiting to help you! Superfast, super-efficient!

I still have not learned to use this app in all its depth, but their triggers and segmentations are amazing. There is nothing not to like in this app.

I had been thinking about switching to Klaviyo for a year, and I am glad I did! I have been using for about 4 months now. I love the multi-step automation email and SMS paths of Klaviyo - I am always in touch with customers in a personalized way. The overall design I prefer Klaviyo to Mailchimp. The interface is clean, easy and full of data. The layouts that come with Klaviyo for campaigns are modern and well-designed. It makes designing emails actually fun again! I am excited to continue to implement all the new features Klaviyo offers in my marketing. The possibilities seem endless and I am already seeing great results!

Because of all the features offered in Klaviyo, there was a learning curve and it took time to implement and switch but definitely worth it and necessary!

It is true that Klaviyo has been the leading email marketing software for some time now. However, there are some signs that this may not be the case for much longer.

Klavyio's integration with almost any product in the market is one of its best features. This allows users to integrate Klavyio into their existing workflows and systems seamlessly. Klavyio's wide range of integrations makes it a versatile tool that can be used in many different ways.

Klavyio's interface is in dire need of an upgrade. It is outdated and does not meet the needs of modern users. The interface is clunky and difficult to use, and it does not provide users' needed features. Klavyio needs to modernize its interface and provide a more user-friendly experience.

I love the ability to integrate Klaviyo with all the essential apps within my eCommerce businesses to enable extremely powerful automated flows to send the right messages at the right time.

I wish the pricing was a bit more comparable to Mailchimp, but when setup properly the results make it worth it. Additionally, I wish the SMS feature was a bit better and more polished.

In August 2015... I was convinced I needed a better email marketing solution with automation. Klaviyo is/was much more expensive than other basic email services (MailChimp, getResponse, AWeber) but the marketing automation was arguably a great investment with good ROI. I integrated K with my site (Americommerce) and discovered that the only way to make K to work was via middleware, "CartSync" which cost about $100/month. It was imperfect. Bare minimum metrics. Marginally useful. I accepted the limitations and launched. Klaviyo support manager's exact words to me were, "Why don't you move to Shopify?" Those words resonated... 10 weeks later when I decided to actually replatform to Shopify, getting Klaviyo support to answer a basic question was a frustrating experience. K support earned a reputation as only slightly better than useless. Then there was the "integration disconnect" bug -- the connector to my Shopify store was shut off by Klaviyo, without notification -- ah, but there was an email -- sent by a spammy server (non-transactional) that never saw the light of day. We learned that K was sending TRANSACTIONAL EMAILS from a marketing server. And this email was getting flagged as spam by many mail servers. In the mean time, I was a presenter at am ecommerce conference and when I asked who used Klaviyo, many raised their hand... then I asked, "is anyone satisfied with Klaviyo support?" -- the room's reaction caused the Klaviyo rep in the room to text his management team - and before the end of the session we were told K was hiring 4 new support reps. SO the consensus was: Klaviyo usually works great Klaviyo has lousy support Klaviyo is relatively expensive as your customer list grows Klaviyo is very powerful. But Klaviyo *had* an issue with their email hitting a spam RBL... When I went to send a preview email for a campaign, it was flagged as spam. When I tried sending Klaviyo subscribe emails from 10 different stores that I knew to use Klaviyo, they all went to SPAM. I was able to get Klaviyo removed from the offending RBL - but until a call from Klaviyo's director of product at T+30 hours, the silence from Klaviyo was deafening. Then Cyber Monday's failure... I'm still a K customer for today, but I will probably not be a customer in 60 days. I still think the product is amazing, but no-confidence in deliverability and the history of limited support forced me to seek an alternative.

Incredibly powerful rules and automation flows. SUPER TIGHT integration with Shopify.

Deliverability is a concern. Support is slow to respond.

It's software that is very easy to use once you get the hang of it. The flow management, template builder works very well. I would say that if you have an e-commerce store, Klaviyo is one of those key software to have. A/B testing also works very well. The newsletter forms also. Overall I had a great experience with this.

The price is the worst part of it, for sure. And this is something that they would need to reconsider as someone who is starting out cannot use their services from the start. Someone starting out will go to another software, get used to that one, and even if they want to make the switch to Klaviyo after a while, it's not easy and they will stay with that worse software for a long time.

With Klaviyo, our e-mail and SMS marketing capabilities have evolved, and we can expand our marketing operations and target new segments of customers. With Klaviyo, we also have a library of analytics for all our previous campaigns, and we've taken advantage of it by keeping its flaws under scrutiny and continuous improvement.

I love the fact that Klaviyo gives us multiple options so that we can filter existing and potential customers and send out promotions and alerts on a regular basis. I love Klaviyo's ability to categorize customers into multiple segments based on their data and past transaction history, allowing for unique email and SMS formatting to suit each segment's needs. I also like the fact that it is easy to create new campaigns by using the ready-made templates provided by Klaviyo, and I also like the ease of importing and preparing contact lists and also scheduling send dates. I appreciate the excellent reports that Klaviyo provides us with, which give us a comprehensive analysis of the interaction of customers with our campaigns, and we can determine by means of these reports the extent of the success of those campaigns.

I haven't had any technical issues with Klaviyo. The user interface is very intuitive, all the tools are clear and easy to use, and I love the fact that there is a support team ready to help us and answer our queries at all times.

The platform itself is great. The level of service from our Customer Success rep is awful. It's like crickets when you try and contact them for an issue. So our team usually contacts both Support and our CS rep. And most of the time Support replies first. You would think a dedicated CS rep who provide a level of service that you'd want to recommend to others. Instead, we never know when we'll hear from our rep. We cross our fingers that Support can answer our questions. I think that's ridiculous. Klaviyo needs to improve this most definitely.

Klaviyo integrates very easily with so many platforms. It's easy to use and has great segmentation tools.

SMS is not great. They recently rebranded which completely throws me off with their new color choice. I almost felt like the rebrand was a way to cover up a whole lot of changes that they didn't want people to notice.

Klaviyo is honestly amazing. We have 260,000 contacts and spend $2100 a month. I love how much revenue it generates for us!

I would say just more integrations would help.

Email marketing. It is the best platform for email marketing.

This is probably the best platform for email marketing I have ever tried. Well, I use it for my online store in order to send twice a week week newsletters to my customers' inboxes. Besides the multiple options that Klaviyo has, which makes it easy to give life to any pattern / combination of emails possibly out there, pricing is really fair, and they count with a free plan as well. Designing is also easy. I have fulfilled all my expectations when it was the time to create emails to be sent to customers. Something that I really like is the local time for delivering emails because sometimes customers have different time zones; if email is supposed to arrive at 9AM, then it would arrive at that time (for customers). Also, I have to mention the extense documentation that Klaviyo has. Customer service is through email, but they always answer back to you in as soon as 2 hours or less.

They could make pricing a little more advantageous for their clients.
