Authorised a $140 monthly subscription. Was charged $1240 + $140 at the end of the month. Klaviyo imports and charges for "profiles" that are opted out of marketing. Do not trust this company.

I am extremely impressed with this platform! It is truly perfect in every way. The customer support team is absolutely wonderful—they go above and beyond to help with everything I need. Highly recommended!

I am loving the Klaviyo app - and have taken the time to go through the suggestions on offer and I am producing stunning flows. I am truly a beginner and Shopify has made it very easy to integrate Klaviyo with Stamped io and it is coming together beautifully. The templates are easy to navigate and edit. I was so tired of paying huge sums of money to outsource all of this and the beauty of doing everything yourself is that you are in control of what your customers see and can stay on brand and make quick edits. Recommend and very happy.

I've been using the free mode for about a year and have seen many data flow results. It expanded the reach of my email advertising. The automated processes were particularly challenging to set up at first, but once I got familiar with them, they really helped in categorizing and identifying customer segments. I'll continue using it. Thank you!

Klaviyo was a breeze to integrate with our Shopify store—just a few clicks, and we were up and running! The setup was super easy, and it instantly synced all our data. We quickly set up our email flows like abandoned carts and welcome series, which have already boosted our sales. The best part? Klaviyo pulls customer data straight from Shopify, making our emails feel super personalized. The analytics are spot on and help us tweak our strategy easily. If you’re looking to step up your email game, Klaviyo is a no-brainer. Highly recommend!​⬤

Danielle M was fantastic at helping today with a few questions I had about our flows. Great support team every time I ever need help. I would highly recommend.

have used Klayvio since the beginning with the store and have found it very helpful. Had a minor issue which I reported to the support team and Antonis from the team sorted the issue out in under five minutes

Completely unreliable software. Sometimes a campaign sends, sometimes it doesn't. Often have to keep repeating setup until it decides to send.

Klaviyo is amazing, the interface is easy to use, and the templates are more than helpful. All in all, a tool, ecommerce would be hard without.

I have literally has the best support experience of my life with Klaviyo. Huge shout out to Danielle M.

I think it's very shady that Klaviyo instantly charges more for additional email recipients beyond your plan level, but that when you clean your list, the plan cost stays at the higher level - unless you dig into the settings and change it back down. A message should come up when 'Active' users drops below your biling level to ask if you want to lower your plan level. It's clearly to maximise revenue - but in an underhand way.

Alyssa D was so very helpful and polite. She provided the answer to my questions quickly and accurately. I love chat support. It's quick and easy and doesn't tie me to a phone. I'm loving Klaviyo!

Awesome to work with! From integration through support, easy set up and use. Highly recommend. illumino360.com

in sort of a nightmare situation now with adding our domain email and changing DNS records. all of our emails are landing in spam. Klaviyo said it was because we lost the confidence of the consumer... not true. this all happened in a week as we were trying to change our email. support is zero help. we said we would need to switch email companies as being without our email marketing for weeks would seriously impair our business, they simply say... sorry to lose you. we literally spent 1-2K a month...switching to omnisend or finding another partner

Cannot be more unsatisfied with the app I've been using for all my stores. They have been charging me amounts that has not been used, and once I decide to downgrade the plan for one store that has not been receiving traffic for 2 months, they remove all the premium features which I just paid few hours ago. Also they don't have any type of customer support (I should have as I paid for the whole month already, but as I decide to downgrade to free plan for the next month, they deactivated every premium feature). I don't understand how a company of this size can do this behaviors

Hands down the best email marketing tool out there. If you aren’t using Klaviyo you’re most likely missing out on great revenue opportunities. Even if you’re using their competition. I know because I’ve tried them all. I first signed up for Klaviyo when it was a tiny startup and liked what I saw, but switched to a competitor when it couldn’t integrate with my eCommerce platform at that time. However, after a couple of years and a lot of frustration I came back to Klaviyo and I’ve seen companies thrive as a result. You have to put the time in, but it’s worth the rewards. 10% of our revenue is regularly attributed to Klaviyo. Their learning tools are great. Take the time to join them on their webinars. Great company run by a great CEO.

The interface is very easy to navigate and the customer service was very quick, I'm quite impressed so far.

Good software and Dalu I in customer service has been really helpful in helping me understand inactive profiles and how to suppress them when not needed.

The platform is amazing -best out there .really happy with how it performs and ease of use . Love the courses . 5 stars BUT the support is lacking .very very slow, limited weekend response , no phone number. Urgent issues when you can’t get into your account -took days to get a response ...very stressful when your business is running through it to not be able to ring , or have any online chat . Fix this and you’ll get 5 stars ⭐️

So simple and easy to use, once set up it does all the work for you. I have recovered so many abandoned carts it pays for itself.
