Great experience and easy to use. Love how I can do it on my own without having to contact several people to get started.

Klaviyo Inc. regarding unfair and unethical billing practices. For the billing period of December 28, 2024, to January 27, 2025, I was charged $8,180.87, despite being enrolled in a plan clearly outlined at $4,088.50.

I have provided Klaviyo with documentation confirming the agreed-upon amount for my plan. Despite this, the company has refused to issue a refund or offer any resolution. Their refusal to rectify this issue is not only disappointing but raises serious concerns about their billing practices and customer support.

Additionally, upon further investigation, I have discovered numerous similar complaints from other businesses regarding Klaviyo's unfair and unethical billing. This pattern of behavior suggests systemic issues that need to be addressed to prevent further harm to consumers.

I respectfully request that Klaviyo:

Issue a full refund of the overcharged amount ($8,180.87 - $4,088.50 = $4,092.37).
Conduct a review of their billing processes to ensure transparency and accuracy moving forward.

I had an issue with Meta Ads integration (not Klaviyo's fault!) and I reached out to their support team. My issue was resolved very promptly and I was able to speak with a technical support agent. From an email marketing platform perspctive Klaviyo has been very easy to work with and I highly recommend it!
