    Aggressive Billing & Overcharging

    Share of complaints42%

    Customers are consistently overcharged due to Klaviyo's billing model, which charges for outdated or fake profiles, ignores auto-downgrade settings, and increases prices without clear consent, severely impacting profit margins.

    RCPT 002★☆☆☆☆
    “Their pricing model is completely predatory. They bill you based on outdated subscriber list sizes, so even after you clean house, you're stuck overpaying for profiles that don't exist anymore.”
