Hi Louise, that's lovely to hear - thank you! Kind regards, Claire
The sales rep Xanthe who sold our company on Klaviyo willfully misrepresented their terms and conditions. After months of marketing and dev investment, compliance disabled our account because our industry is not represented in their terms and conditions. We clearly stated our industry during sales and onboarding and complied with all GDPR regulations. We were not only told that our industry is represented, but that Klaviyo represents competitors in the space. This was a major loss of investment for our company.

Hi Aubrey, thank you for taking the time to write a review about your experience with Klaviyo. I'm sorry to hear about the frustrations you've described. Please look out for an email from me in regard to this matter. Kind regards, Claire
There are some things to get used to if you are new to using Klaviyo, but the support agents give nice detailed responses and try to answer all your questions.

Hi Kevin, thank you for taking the time to review Klaviyo. We appreciate the feedback! Kind regards, Claire
So after many, many tries and much wasted time, Klaviyo finally managed to send me the correct link to sign up. Then I uploaded 489 contacts which magically showed up as 818 contacts (different price tier) in my Klaviyo list. But what's worse is that support (or probably a bot) sent me an email asking if there was anything else I need help with. So I replied (several times) with the list issue. Then they don't answer those emails either. Seems like the only way to get their attention is to tell others about my poor experience. Reply: given how many emails I’ve written my contact info should be in your system if you actually had a support system. My company is Mind+Beauty on Shopify.

Hi Elizabeth, we strive to provide superb customer service so I'm very sorry to hear about the difficulties you've encountered. Please let me help by providing some contact details so I can follow up with support. Kind regards, Claire
The new pricing structure is a joke. Easily the most expensive platform out there now. I'm in the process of moving all 11 clients away from Klaviyo as all of them are now paying almost 3x more than they were before the pricing update. It's a shame because this used to be a 5* product.

They simply don't pay agency fees... STAY AWAY!!! If you're an agency bring your clients' campaigns somewhere else!
