We have been using Klaviyo since 2018
We have been using Klaviyo since 2018, Never had issues with them up until today... When going through their different billing plans, accidentally upgraded our plan. Out team immediately took action, and e-mailed Klaviyo support, within less than 1hour of upgrading the billing account. To our surprise, Klaviyo responded back to us with a "template" e-mail. Saying that according to their T&C we cannot get our money back. NOTE: We e-mailed Klaviyo immediately after changing our billing plan. NO email were sent to customer, to account for plan usage. There are other alternatives out there, we have been looking at Sendlane.

Hi Mert, thank you for taking the time to write a review. I'm sorry that this matter has caused you some frustrations but we were unable to refund your upgrade because you substantially exceeded the volume covered by your original plan. Kind regards, Claire

Very good onboarding experience
Very good onboarding experience We switched to Klaviyo a few weeks ago and already notice amazing results for a price that is only a portion of what we used to pay with our previous solution. Klaviyo is very easy to use and training our collaborators was quick and efficient.

Absolute waste of money
Absolute waste of money, they promise the moon and then when large portions don't work they refuse to issue a refund.

The fact that they will charge you to…
The fact that they will charge you to even have the option to contact customer service is mind boggling to me. All I wanted to do was reach out and ask them if they have any old code on my theme and remove it if that was the case. I am not going to PAY to have to ask them to remove the code. Absolutely insane strategy.
Response from KlaviyoMay 22, 2024
Hi Joe, thank you for taking the time to write a review. Customers who pay for a Klaviyo account have access to support 24/7. Free accounts have access to support for the first 60 days and if they still need support after that, they'll need to upgrade to a paying account. We're very transparent about our support offering - you can find full details here: https://help.klaviyo.com/hc/en-us/articles/115001002272
