Comparison
Stocklet vs Back in Stock by Appikon
Back in Stock by Appikon is one of the most established restock-alert apps on Shopify. Stocklet covers the same core job — capture demand on sold-out variants, email the shopper when inventory returns — but changes where that email lands and what you can prove it earned: a one-click checkout instead of the product page, and recovered dollars instead of opens and clicks.

Why teams choose Stocklet
Appikon's app is a capable, widely installed restock-alert tool, and if all you need is to notify shoppers that something returned, it does that. The question is what happens after the notification. Stocklet's email drops the shopper into a pre-filled Shopify checkout with the exact variant already in the cart, removing the return trip to the product page where restock sales most often leak.
Stocklet also reports the metric a finance team will accept. A hidden cart attribute ties each recovered order back to the original signup, with a 7-day email-and-variant fallback for shoppers who came back directly, so the dashboard shows recovered dollars rather than send and open counts.
Klaviyo sync is included from the $9 Starter plan, and there's a permanent free plan with 50 alerts a month — so you can run Stocklet against your own catalog before deciding, without a trial clock.
