Comparison
Stocklet vs Notify! Back in Stock
Both apps capture demand on sold-out variants and email shoppers when inventory returns. The difference is where that email sends them — and what you can prove it earned. Stocklet links straight into a pre-filled Shopify checkout and reports recovered revenue in dollars, not opens and clicks.

Why teams choose Stocklet
If you want the restock email to do one thing — turn pent-up demand into a paid order — Stocklet removes the step that usually leaks the sale: the return trip to the product page. The shopper taps the email and lands in checkout with the exact variant they waited for already in the cart.
Stocklet also measures the outcome your finance team cares about. Every email carries a hidden cart attribute that ties the resulting order back to the original signup, with a 7-day email-and-variant fallback for shoppers who came back on their own. The dashboard shows recovered dollars, not just send volume.
Klaviyo sync is included from the $9 Starter plan, so your existing flows fire on every new waitlist signup without paying for a top tier. And there's a permanent free plan — 50 alerts a month — so you can prove the model on your own catalog before committing.
