There is zero customer support from this app on the free plan, not even email. I know many aps will limit support on free plans (e.g. you don't get live support), which is fair enough. However, you can't even reach anyone by email if you have a problem without upgrading to a paid plan. We are a new and growing business so where we can we are using lower cost or free plans to begin with, but will of course upgrade as appropriate as we grow. But if this is how Klaviyo approach customer support, why would I upgrade to a paid plan. To be fair, for what I am currently using for at least, the app works well and is fairly user friendly once you get used to it.

Easy to ingtegrate and use. We use Klaviyo to send all our emails - flows, marketing and more. The product feed and linking is quite easy.

I highly recommend the Klaviyo app in Shopify for email marketing. It is easy to use, has great training and integrates beautifully with Shopify.

Simplified our approach to email marketing, easy to use campaign and transactional email creation tools, simple to use automation/flow editor.

Klaviyo is an easy-to-use platform that is robust enough to grow with a business, and straightforward enough to get junior staff trained & ready to utilize advanced features/functionality in a hurry. The amount of content provided in the Klaviyo knowledge center is excellent, and I especially appreciate the amount of content marketing the team does by way of publishing best-practices, benchmark, and other such guides.

They're just the best. We use them for both Email & SMS. Everything just works but if for some reason you're trying to solve for an edge case, support is always there when you need them. Have been a customer for 4 years for our brand and never considered switching. Have recommended about a dozen other founders to Klaviyo. They're the best!

I don't know how, users find this application great! -Email? In short, complicating less competitive than email Shopify because there are short features is less good. You really have to try to put parameters for logo and products etc. that are not already connected to our shop. -pop-up? only one that could be interesting on this application. -SMS? Drop too much Australian confidential policy that blocks everything because if you are in Europe or France not title company in this country Australia impossible to use sms. In addition, limited free version 54 days after upgrading to X price! Nice design ok may can feature to work from in without having any know problem.

The best email marketing app I've used. It sure did take some getting used-to, but once you do, the automations and flows are powerful!

Me encanta trabajar con Klaviyo. El email marketing simplifica mucho todo el proceso de ecommerce.

Klaviyo has made business a breeze. Love how integrated it is with shopify and all of their features. Highly recommend!

使用起來真的很方便，是少數不會迷失方向的插件！ 功能非常多且齊全，還能做AB testing，會願意一直使用下去。

I am loving the flexibility and ease of use of Klaviyo and all the new features to help improve KPI's.

Klaviyo employees always help quickly if I have a question. This time, well helped by Mandy! Their chat is very useful.

Klaviyo is MUCH better than the others! Klaviyo is VERY EASY to navigate, yet has every tool you need.

I highly recommend this program for your business. it's easy, professional and defiantly provides results.

Pricing is really predatory, it increases waaay above what they initially show and they automatically charge you more. When installed, it created a bunch of fake accounts which were just Google Bot "subscribers" with fake emails and now charges me at a much higher price tier just because it considers those somehow to be real people and counts them toward my total. Pretty ridiculous. They don't prorate nor will they allow any free trial or test of their email system. Templates for emails weren't very good and were difficult to use.

I would give a 0 if possible. DO NOT SWITCH to klaviyo. We have been in business for 9 years and when we switched to K, our 60% open rate dropped to 20% and all of our emails land in SPAM. All they could say was it was losing consumer confidence and we have to do their "reputation repair" Klaviyo totally screwed us on all big sales. Any one have any idea who else would be a better alternative? Need to get out of klaviyo ASAP

Klaviyo has made sending promotional emails a breeze. Love how easy it is to add new emails through Shopify POS and through our website. Copying campaigns and blocks super easy too, saving time and optimizing our reach. Highly recommend!

Peter was incredible helpful today with my questions. He has been the most informed and easy going Klaviyo support communication thus far. Thanks, Pete!

Klaviyo makes it super easy to send emails to your target audience and it has definitely increased my sales with each email I send!
