Klaviyo: Email Marketing & SMS

This app is well marketed, and go to tool for e-commerce email marketing. However be cautious that installing klaviyo shopify app and inserting their .JS to your store it takes 15 website speed points out of 100 possible speed points. Our developer pointed this out that klaviyo app inserts a ton of not needed stuff to the site that kills the speed performance score of the site. WE ran a test where we removed their .JS from our store and our google speed insights score went from 20 to 35... Klaviyo please fix this

You can't do "notify when in stock" or abandoned cart capturing on Shopify 2.0 themes like Dawn. Bummer.

We used to love Klaviyo but like all techs these days phone support is obsolete and live chats are being abandoned during critical times. Chatbot assistance sends you into a frustrating loop of never-ending bot questions/answers. Complicated issues cannot be communicated and emails go unanswered. Chat is supposed to be live 9-5 EST but no one is ever available and you're told to just email. Will be looking to switch as the service is no longer top notch. Klaviyo always stood out on top, now they are on the bottom. Cost vs value is just not there.

I have been using this app for long and now I am not able to pay them, to upgrade my plan, we are losing important dates. Emailed them several times with no response.

Terrible experience with Klaviyo. Not what they used to be. Customer Service took a month to get back to me! 1 MONTH. Can you believe that. They Charged me 3 times the monthly costs (supposedly someone activated this that is not anymore in the account) This should be something only the owner should be able to do! The one who pays the bills. Within hours of getting the charge FOR THE NEXT MONTH, I told them to reverse it. Klaviyo like the bad company they are now (looks like they have to show numbers because they are listed) they didnt care and responded back in a month, that there is nothing they can do.

1. First if you Bill in advance you should refund if someone gets back to you within hours.
2. Only the Account owner should have the power to increase 3x costs.
3. As a serious company you don't need 1 month to answer a customer.

If you can use another Email App. Do yourself a favor and don't use Klaviyo.

We will be definitely switching.

Trash email provider. Ruined our deliverability and billed us 300 usd more than the actual bill and when we asked for a refund they just disabled our account and we can no longer send emails to customers.

I wish their fee was more reasonable , they are extremely expensive. Gosh $300 for 13k list. Even my whole Shopify account cost $75 a month. Charging that much is ridiculous. Seems like for every 10 sales person they hired, they hired only 1 customer service. Its hideous to not be able reach customer service for a company their size and funding.

It's not worth your money, nor your time. Customer service is very poor. I received contradicting info from a couple of representatives. Unfortunately, the support team is not trained sufficiently to give proper client support.

every time you contact the chat it is 8 hours, and they are not fully trained and don't have an answer to any technical issue so you have to close and start a new chat hopping you'll get somebody else! no tel support.

They seem to have bots that create fake subscribers, increase your amount of contacts and force you to an higher price plan. Oh, and you need to get the higher price plan in order to reach customer support. Avoid at all point if you don't want to waist your time.
