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.

I love the ease of use, likely because we've used it for so long and I'm so familiar with the platform. When they do make updates, it's not too much at once in the way many companies go about updating. The email editor is simple, the ability to a/b test is as well. Overall great functionality.

I think the native content boxes can be more customizable although they are improving slowly. I'd love to be able to set the font sizes on mobile to be a percentage of the size on desktop instead of choosing multiple font sizes. They used to have amazing support, it's nowhere near where it used to be.

Being a developer myself, I informed the Klaviyo team of the deprecated code errors their plugin was displaying on peoples websites, and to the fact that their plugin slowed customers websites down drastically. The reply I received a couple of days later was: "Unfortunately we do not update our plugin very often - but our team will get around to it eventually." This was 2 years ago, and the plugin still has not been corrected. So it still produces errors, and still slows peoples websites down.

Klaviyo is extremely easy to setup, especially compared to its competitors. You have the freedom to link Klaviyo with your Wordpress/WooCommerce website seamlessly. Everything can be automated! Such as emails after order received, emails after payment received, multiple emails after certain time duration's for things like newsletter subscriptions and a lot more options are available to include users website Wishlists, items they left in their shopping carts to remind them, and all emails are fully customisation using the Klaviyo's inbuilt email form designer. You can also arrange customer lists, newsletter subscription user lists, and any other lists you may require. The possibilities are endless!

Using Klaviyo on your Wordpress website as subscription signup form slows your website down, a lot! Although unnoticeable to customers surfing your site, Klaviyo also throws a few error on your page as it uses deprecated (out-dated) code. If the Klaviyo form builder doesn't produce the look/type of form you require, then you must build the form yourself by coding direct on your website (Which beats the point of having a form builder). The Klaviyo plugin does not update, and never announces that there is a new version. You must remove the plugin from your website, manually download the latest version from their website, and then upload/install/activate the new plugin. There is no option to change languages or string translations of forms, form input boxes, or form buttons. And these translations cannot be picked up in Wordpress plugins such as Lingotek or Polylang. The same applies to the confirmation pages after the user submits the forms.

We’ve used klaviyo for years, it worked great with Magento and even better with Shopify. The flows are very powerful and everything is so easy to use. They keep releasing updates too so it’s it’s very good value for money.

Definitely the drag and drop email template builder and the flexibility it has for mobile. The sign up forms are just as easy to make. The whole platform is very user friendly.

The sms campaigns are pricey and you’re very limited on character count. Watch out for your sms usage as if you go over you’ll be auto upgraded to the next payment tier.

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.

Klaviyo has quickly become the gold standard for high end email automation.

Expensive and less focused on the ecommerce industry than it could be.

I use it everyday and love all the info they provide on how to improve OR, CTR, and revenue. It's very easy to create emails and flows.

They switched from account reps to general customer service questions. We have a small team so for someone who is learning about email marketing it was really nice to have a personal relationship with the reps who could help guide you.

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.

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!

Good for analyzing first part data.Pretty good integration system with e.g. Shopify, Facebook etc.

Css editor is okay but would need additional software or programming skills to make high class emails.

I have no complaints with Klaviyo. It's a great system I use everyday.

Klaviyo is the best Ecommerce email platform. It's the place for your lifetime value and segmentation strategy. And the customer service is second to none. It has so many features, and can do anything you need.

It's expensive, so if you're looking for something cheap, look elsewhere. Since it's also tiered, you should have a minimum number of subscribers and revenue per month to make it worth it.

The integration with Shopify Stores and the ease of building flows makes this a game changer. Additionally the bulk discount code builder gives Shopify functionality outside of Shopify that makes "one less app" for my store. Finally the native Form Builder in Klaviyo is very easy to use.

I wish one Klaviyo Account could connect to multiple Shopify Stores, this causes some problems for our operations. Additionally I wish building segments was faster, some advanced segments take very long to build.

Klaviyo is extremely easy to use. For employees that are less tech savvy, it's a great option. The integration with Shopify is pretty much flawless. MMS messaging is extremely easy for both broadcast sends and automated sends. If you have an online store, I don't think you should use another automation platform.

Segmentation and triggering workflows based on user segments are a bit more limited than tools like Braze or Iterable.

The transition was fantastically simple, the IP warming was easy and everything about Klaviyo has made us happy so far.

I greatly enjoy using Klaviyo. We've utilized MailChimp, Zaius and more in our quest for a long term ESP that we are happy with and Klaviyo has been it. It's not the cheapest out there but it certainly isn't the most expensive and it feels like you really get a good value for the advanced features. The Shopify integration is easy and seamless and the Live Chat customer service has been responsive and helpful everytime. Very pleased with them.

Honestly, perhaps the only thing I don't like is that layout isn't as sleek as some of the other options but it's a very minor point.

My go to solution for ecommerce clients. It has automation ,good templates and everything else

Robust features that just work. It's a bit getting used to but you can do most of what you want with them Really good templates for those starting out and experienced as well

Their onboarding process could be easier They have tutorials but they're fuzzy and should be made available with webinars being an option.

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.

Overall, the experience has been great. I think they hype some of the buyer indicators and data collection, which is fine but nothing special, but it's a great email platform.

The IP warming and migration process was very smooth with no hiccups. The Klaviyo team are experts and it shows. We felt confident in their ability to successfully transition ESP platforms. The product itself is quite good and does everything you would expect it to.

Like all ESPs, it has it's own unique idiosyncrasies. No deal breakers, but some of the functions can be a bit clunky.

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.
