Back-in-stock alerts that convert before the second sellout
Back-in-stock notifications are the ultimate high-intent moment. The customer already told you they want to buy — they signed up for the alert. But traditional email-based restock alerts fail because by the time the customer sees the email, clicks the link, and navigates checkout, the product has sold out again.
Text-based restock alerts with reply-to-buy close the sale in seconds. The customer gets the text the moment inventory is available and replies to purchase. First come, first served — and the fastest channel wins.

How most brands handle back-in-stock notifications
The typical flow: customer signs up for a "notify me when back in stock" email on a sold-out product page. Days or weeks later, when the product restocks, they receive an email with a link back to the product page. By the time they open the email (hours later, or the next day), click through, and add to cart, there's a good chance the product has sold out again — especially for high-demand drops.
Email-based restock alerts have three failure points: delivery delay (emails can take minutes to hours to arrive), open delay (customers don't check email in real time), and checkout friction (the customer still has to navigate a full purchase flow). For limited-inventory products, these delays mean the customers who explicitly asked to be notified still miss the restock.
The result: brands re-stock a product, send notifications, and still leave revenue on the table because the notification channel is too slow and the purchase path is too long.
Restock alerts with instant reply-to-buy
With AudienceTap, back-in-stock alerts are sent via text the moment inventory is available. The customer receives a message: "The [product] you wanted is back in stock — limited quantity. Reply YES to claim yours." They reply, and the purchase is confirmed instantly using their stored payment method.
There's no email delay, no link to click, no page to load, and no checkout to navigate. The customer who signed up for the alert gets first access because they can act in seconds, not minutes. For high-demand products, this means restock alerts actually convert instead of creating a second wave of disappointed customers.
Brands can also layer inventory limits into the text itself — "Only 50 available, reply YES to claim" — which adds urgency and rewards speed. The customers who were genuinely waiting for the restock get priority access, and the brand captures revenue at the exact moment supply meets demand.
