AI Product Alert Notifications
Tapcart's AI Product Alert Notifications detect inventory and pricing changes across your Shopify store and automatically send personalized, AI-generated push notifications to the customers most likely to convert, no manual setup or copywriting required.
Each notification is written by AI using product context, the customer's specific interaction history, and your brand's tone from AI Tuning. The AI learns your preferences over time as you give feedback with the thumbs-up button on notifications you like.
Alert Types at a Glance
AI Product Alerts includes three campaign types, each targeting a different shopper moment:
Back in Stock
Low in Stock
Price Drop
Alert Type | Trigger | Who Gets Notified | Audience Lookback |
Back in Stock | A previously out-of-stock product or variant becomes available again | Customers who carted, wishlisted, or browsed the product while it was out of stock | 30 days |
Low in Stock | A product's total inventory drops below your configured threshold (default: 20 units) | Customers who viewed the PDP or have the product in their active cart | 30 days (PDP viewers); no expiry for active carters |
Price Drop | A product's selling price decreases by your configured threshold (default: 10%, minimum: 5%) | Customers who browsed or carted the product but didn't purchase it | 30 days from most recent engagement |
Note: Each alert type can be individually toggled on or off. You can run one, two, or all three simultaneously.
How to Enable AI Product Alerts
From your dashboard, go to Engage > App Notifications > AI Notifications tab.
Click into the AI Product Alerts card.
Select Start Campaign on the individual alert types you want to activate: Back in Stock, Low in Stock, and/or Price Drop.
Review and adjust your AI Tuning settings for each active alert type (optional but recommended).
Click Save. Alerts will begin sending as triggers are detected in your Shopify store.
Tip: We recommend enabling all three alert types to maximize re-engagement across inventory and pricing moments.

AI Tuning
AI Tuning lets you control how each alert type behaves. The settings below are available within each campaign's configuration panel.
Low in Stock
AI Tuning Settings
Inventory Threshold (default: 20 units): Send a Low in Stock alert when a product's total inventory drops below this number. Set this high enough that customers have time to purchase after receiving the alert as products that sell out before the customer opens the push create a poor experience.
The threshold applies at the store level across all products. Alerts only fire when inventory crosses below the threshold. If inventory is already below it and gets another update, the alert won't re-trigger. Changing the threshold does not retroactively fire alerts for products already below the new value.
Price Drop
AI Tuning Settings
Minimum Price Drop % (default: 10%): The minimum percentage decrease in a product's selling price required to trigger an alert.
Price Drop evaluates against the last known selling price, not the original MSRP. If a product went $100 → $80 → $70, the second drop is measured against $80 (a 12.5% drop), not $100.
Discount Codes
Add Existing Discount Code: Add a Shopify discount code so the AI can naturally weave it into the push notification copy. This is especially effective for Price Drop alerts to reinforce deal urgency.
Audience Tuning
Audience Overrides let you customize notification settings for specific customer segments so you can tailor discount codes and AI instructions based on purchase history or behavior.
Click on a segment (e.g., Never Purchased, New Customer, Repeat Buyer) to expand it.
Discount Code: Enter a code for this segment. It replaces the global discount code for customers in this group.
Additional Instructions: Write custom AI instructions for this segment. These replace the global instructions for customers in this group.
Preview: Generate sample AI-written notifications for each segment before saving.
Save: Changes take effect on the next notification cycle.
Additional Instructions
Provide extra guidance to help the AI match your brand's tone, voice, or messaging preferences. Instructions apply globally across all alert types, unless overridden at the segment level in Audience Tuning.

AI Creativity
Controls how varied and expressive the AI-generated push copy is. Higher settings produce more creative messages; lower settings stay closer to a predictable formula. The default is 4.
Training Data
A collection of notifications you've given a thumbs-up to. These are used to help the AI better align with your brand over time. The more feedback you provide, the more personalized your alerts become.
What the AI Writes
The AI tailors copy to both the alert type and the customer's interaction history:
Back in Stock: References how the customer interacted - "Still in your cart," "On your wishlist," or "You were checking this out." Leans into scarcity framing. When possible, references the exact variant (e.g., "The Denim Skort in size M is back").
Low in Stock: Uses urgency without fabrication - phrases like "almost gone," "selling fast," or "only a few left." Never exposes the exact inventory count. Viewers get copy like "That sneaker you checked out? Almost gone." Carters get "Heads up - what's in your cart is selling fast."
Price Drop: Includes the product name and magnitude of the discount (e.g., "now 20% off" or "price dropped by $15") with urgency framing relevant to the customer.
All notifications deep-link directly to the product detail page (PDP) and display the product image pulled from your Shopify catalog.
Inbox
AI Product Alert notifications land in the shopper's in-app Inbox, so they can revisit the alert even after dismissing the push.
Push opt-in required: Customers must have push notifications enabled for your app to receive AI Product Alerts.
FAQ
What happens if a product restocks and immediately sells out again?
Back in Stock has a built-in 3-minute debounce window. If the product goes back to 0 inventory within that window, the notification is cancelled and no alert is sent. This prevents false triggers from brief inventory spikes.
What counts as a price drop for the Price Drop alert?
A decrease in the active selling price - the price a customer would actually pay at checkout. "Compare at" price changes alone do not trigger an alert. The drop is always measured against the last known selling price, not the original MSRP.
Will my Low in Stock threshold retroactively trigger alerts if I change it?
No. Changing your inventory threshold does not retroactively fire alerts for products already below the new value. Alerts only fire on the next inventory change that crosses below the threshold.
Will a customer who already purchased a product receive a Product Alert for it?
No. Customers who have already purchased the product within the relevant lookback window are excluded from the audience for all three alert types. For Back in Stock, the exclusion applies to purchases made since the restock event.
Does the exact inventory account appear in Low in Stock Notifications?
No. The AI uses qualitative signals only - language like "almost gone," "selling fast," or "only a few left." The exact inventory number is never exposed in the push copy.
Do AI Product Alert Notifications land in the app Inbox?
Yes. All three alert types appear in the shopper's in-app Inbox, so they can revisit the alert even if they dismissed the push.
