How It Works
The signal, not the noise.
Newsletter Intelligence
We subscribe to every brand's email list so you don't have to. Flash sales, sitewide events, early access — we catch the signal as it arrives. Your inbox stays clean.
Signal Filtering
Every promotion is classified by scope, depth, and rarity. We surface only sitewide and category-wide events that cross your threshold. Promo codes, loyalty discounts, and one-time offers are filtered out.
Expanding Coverage
Additional detection layers — site monitoring, SMS signals, structured data cross-referencing — are being added over time. Coverage improves as the catalog grows.
Fewer alerts.
Better timing.
