NotifyMe ‑ Warnings and Labels vs Fleeta ComplyGate

Display a product warning exactly where shoppers need it: product page, add-to-cart popup, cart page, and cart drawer. Create customizable product warnings, warning labels, and warning popups using cart rules, product tags, collections, variants, or vendors. Highlight shipping costs, extra fees, allergens, low stock, limited offers, best sellers, and new arrivals to reduce returns, prevent surprises, and increase conversions. Fast setup, no-code controls, and flexible targeting for every store.

ComplyGate blocks checkout when a restricted product is being sent to a state or country where you cannot sell it, and tells the customer why in plain words. Rules are by product, collection or tag against a list of destinations, and they run inside Shopify checkout so nothing depends on the theme. Built in the UK by Fleeta, free right now.
