Klaviyo: Email Marketing & SMS

Klaviyo is such a buggy horrible integration that I'm going to try and get my client to change. I have a sign up form teaser on my client's shopify store that is not part of any sign up form. I've literally turned off every sign up form, every flow, and even disabled Klaviyo from Shopify, and still this Klaviyo teaser is the site. I've contacted support and got the typical copy and paste, go to sign up forms to delete your teaser but there is no live sign up forms, there is no sign up forms that use this teaser, it doesn't exist. Either it was deleted previously and the code still continues to be on the site without any way of removing it and Klaviyo doesn't want to help to fix their broken buggy product.

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

Great product but support since the IPO has dropped, the support teams aren't given any powers to do anything so you can wait weeks/months from connected departments. If you need/think you might need to move quickly then choose another vendor.

Took about 2 months to try and get Klaviyo to integrate with Shopify tags with lots of back and forth between support who weren't able to assist me properly, rather just sending me a link to an article. We were also overcharged for 3 months and still yet to receive our money back.

Set up with Omnisend and immediately the integrations of profile data, segmentation and shopify tags were there without me even paying for anything.

No support after starting to use paid version. We had technical problems and could not activate any features. Support was unresponsive, did not help to solve any issues, not even freezed the subscription until WE solve them.

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

The interface and features are really impressive, so too the pricing promoted with the app-store. Once you are using it and your member numbers get over a few thousand, the costs skyrocket. Then if you uninstall it, beware. The pop-up windows for my newsletter sign-up remain. Shopify could not assist and referred me to Klayvio. This problem is still yet to be resolved and creating a horrible user experience. I think if someone uninstalls it should be a clear and clean removal and not this level of entanglement and impact on users. I regret signing up in the first place.

4 days of working to set up a simple landing page with an email capture form and an automated redirect after submission. Experience so far:
- form editor is terrible
- forms are not responsive across desktop to mobile (and editing for two platforms in the editor is a not usable)
- limited logic capabilities moving through form submission flow
- forms not saving consistently (it has been random for the past several hours)
- forms not saving to designated lists
- backend and admin is really unsophisticated and illogical
- support (email, free plan) is slow, typically get the ticket closed type of support. In fact, in the past 36 hours, I have twice waited 12+ hours for a response and when the responses finally came I was called Nick and Kate (neither are my name) and the answers were not for me. I had to submit a second ticket to get a response to my first one.

I could go one. There is a reason why over 10% of these ratings are 1 star

So frustrating because I am now looking for a new solution to what should have been an easy requirement to solve

It's expensive and the customer support is terrible.

Their form stopped to shop up without notice as I experience unmatching data analytics between how many customer left an empty cart and then indeed a form should be shown up.
On top, I understand perfectly provide a payment tier for fast support but eliminate it as a way to resolve something that seems due to their feature not working, I think isn't the best experience.

That's why I am proving 1 star.
P.S the answer litterly show the Klaviyo did not understand that they do have a bug into cart detecting form as it is not shown at all to people thus let me loose many many people to signup.
