Checkout Alerts Shopify Apps – Analytics & Insights

Blockify Checkout Customizer holds the top spot for checkout alerts with 28.9% market share, but the gap to challengers is closing, -11.9pp ahead of Melon Minimum Order Quantity (40.8%). Yuko Minimum Order Quantity sits at #3 with 20.4% share, rounding out the top tier.
