Acoustic vs. Klaviyo: Compare marketing platforms.
Acoustic catches a customer circling a product before they've bought anything at all, before there's even enough order history to build a score. Klaviyo needs a pattern to score. Enough orders, enough history, enough time. By the time it flags something, it already happened. Catch intent while it's still forming.
