How Klaviyo and Substack compare

Klaviyo is the marketing brain of many online stores. Deep integration with Shopify and other platforms, behavior-based flows, predictive segments, email plus SMS plus push, and reporting that ties every send to revenue make it the standard for brands that live on repeat purchases. It is powerful and it is priced for that power.

Substack made paid newsletters normal. You write, it sends, and readers can subscribe or pay in one click. The network effects are real: recommendations, Notes, the app, and discovery bring new readers you did not have to find. There is no monthly fee, and for a writer who wants to write rather than run software, that is a gift.
