Klaviyo: Email Marketing & SMS

Very bad, almost lost customer service. When we have a problem, it is difficult to get any help. And for live chat, wait for long and long time, waste my time! And it is expensive, very expensive!

I've used this app for a long time with my shop but suddenly my products stopped showing in my emails. When I reached out to customer support I was informed that in order to receive support I had to upgrade my plan. I refuse to support a company/app/business that refuses to provide free customer service. Quickly deleted this app from my account and will not be reinstalling.

Been trying to get it to work for 2 days now but there is always something wrong with the popup either on mobile or desktop. Random buttons or text go missing for no reason when they are displayed in the customizer and then all of a sudden they're gone. Was planning on switching from mailchimp but nevermind!

Disabled my account for no reason, then sent me a questionnaire of over 20 questions about the business in order to grant access to me again. I've waited over a day to resolve this issue and wasted many hours with the customer service.

I would highly recommend using another app. This one is horrible, I got this set up luckily under the free plan and I went to use a test email that I sent to myself and my account was disabled. I reached out to customer service to find out why and got some robotic answer.
The only thing I can think of is the fact I sent out two TEST emails to myself, which I still have yet to receive, and got disabled. What bothers me most about that is in the statement they sent me about anti-abuse is. They stated "You may receive performance alerts and warnings from us", I never received any notice, when I asked the customer service rep, if you can even call it customer service, I still have not gotten a response from 12 hours ago. I will be deleting from my store and using another app.

Installing this app was the root of all disasters, basically no service, brought my website down, lost thousands of dollars in ad dollars, my website was grayed out and stuck, couldn't click on any pages, the fees were extremely expensive, When you increase email activities, he doesn't even have any reminder to increase the fee, and directly upgrades your fee in the bill. Rogue behavior, opaque charges, stay away from klaviyo, is away from disaster.

This is less than 1 star I will never use it again
I have been designing my campaign the whole day then it sent an empty template to all my customers!!

Very bad customer service. Even the small Email service providing companies have a live chat option for free plans, but in Klaviyo at least email support isn't available. the free plan only provides 500 monthly email sents and 250 contacts. in the Shopify app store, they've mentioned that they provide 500 contacts,but not true.

When I closed my Klaviyo account I forgot to close the subscription form as well, and now that I can't log in to my account anymore, this forms popup is still showing up in my store! It is gonna hijack my user information.

So far, terrible. 0 Onboarding. Just a "Take a look at our guides and ask questions in the community". Erm... that isn't really what I'm paying $110 a month for... I expected someone to guide me through the process of getting things set up and ready to go. I'm not expecting someone to create anything at all, pop-ups, flows, lists. I am literally asking for the basics...

UPDATE: So after numerous requests and questions to support. They either don't want to help - or they just give you a standard link to a support guide. Do you honestly not think I tried that already??
