The best email marketing platform I've ever used. Also, their support is above and beyond helpful in training you on best practices to ensure email deliverability. I can't possibly recommend them enough.

Works well and has great analytics and segments and is easy to build campaigns. Can get pricey as you grow particularly SMS is very expensive

Everyday I learn more and more of what I can do with the app. I am not a "techy" person but so far this has been extremely helpful. I had an initial conversation with someone from the Klaviyo team and that were super informative and very helpful. Looking forward to seeing how it all works in the future

Has to be THE WORST customer service I have ever encountered. No chat, no phone number, only email, which is promptly ignored. I've been waiting a week for them to respond to an account access issue. Can't do much if I can't access my account. No need to point out the irony of a marketing company that doesn't seem to understand that their customers, the ones that pay for their service, need prompt, helpful support every now and then.

Highly recommend Klaviyo. It's super easy to set up on your Shopify store, there's lots of support, the metrics you get straight out the box are amazing and visual too. Perfect for marketing your product and understanding what your customers better! The Klaviyo team are quick to reply, helpful and knowledgeable.

I am working with a really great ecomm group and they have templates that have been easy to import and work with.

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
