## Setup

* [Klaviyo integration instructions](/data-inputs/platform-integration-instructions/klaviyo-integration)

## Common caveats

* Email/SMS attribution depends heavily on consistent UTM tagging.
* Platform-reported conversions can differ from warehouse-reconciled revenue due to attribution windows and deduplication.
