Back-in-Stock, Low-Inventory, and Price-Drop Alert

Use this skill only after applying the 00-email-marketing-guardrails skill (../00-email-marketing-guardrails/SKILL.md).

What and why

These alerts notify a shopper when a requested item returns, a relevant item reaches a real stock threshold, or a previously viewed item has a verified price drop. [KL-STOCK-01][KL-LOWSTOCK-01][KL-PRICE-01]

When and where

• For back-in-stock, trigger only for people who explicitly requested notification for that item and send when inventory actually returns. [KL-STOCK-01]
• For low-inventory or price-drop campaigns, use eligible identifiable shoppers with relevant viewed/checkout behavior and accurate catalog data. [KL-LOWSTOCK-01][KL-PRICE-01]

How

• Send promptly after the qualifying inventory or price event; low-inventory guidance recommends no unnecessary delay. [KL-LOWSTOCK-01]
• Include the exact product/variant, current price, availability state, and direct product CTA; do not imply a false sellout or discount. [FTC-01][KL-PRICE-01]
• Suppress people who already purchased, recently purchased, face unavailable inventory, or no longer meet the trigger conditions. [KL-LOWSTOCK-01][KL-PRICE-01]
• Avoid repeated alerts when inventory may disappear quickly; one timely message is safer than an uncontrolled sequence. [KL-LOWSTOCK-01]
• Measure click-to-product, conversion, revenue/margin, time-to-purchase, out-of-stock clicks, unsubscribes, and complaints. [MC-GA-01][MC-CONV-01]
