Shopify Ops Glossary

Waitlist

A list of customers interested in purchasing a sold-out product when it restocks.

Definition

A waitlist allows sold-out Shopify brands to capture demand without losing customers — notifying them when stock returns via email or SMS. Apps like Back in Stock and Klaviyo flows automate waitlist notifications.

Why It Matters for Shopify Brands

Waitlist management is a revenue retention tool — without it, sold-out customers go to competitors. With it, back-in-stock notifications convert at 20–30%, recovering revenue that would otherwise be lost.

Benchmarks

Back-in-stock email open rates average 65–75% (versus 20–30% for promotional emails) with conversion rates of 20–30%.
