What the observation means

StoreRadar detected a public Omnisend signal on these stores. A public Klaviyo signal was not detected in this filtered cohort. This is a detector non-observation; it does not prove the excluded app is absent or incompatible.

Counts describe public storefront observations in a dated snapshot. They can change as storefronts and their visible signals change.
