Back-in-Stock Email

A back-in-stock email notifies subscribers that a previously sold-out product is available again. Because recipients asked to be told, these emails carry exceptionally high intent and conversion rates.

Also known as: restock email, back-in-stock notification

When a product sells out, demand doesn't disappear — it waits. Back-in-stock emails capture that waiting demand and convert it the moment inventory returns.

How do back-in-stock emails work?

Shoppers opt in to be notified about a specific out-of-stock item. When it's restocked, an automated email alerts them immediately, often with a direct link to buy.

Why do they convert so well?

The recipient explicitly requested the alert and already wanted the product, so intent is extremely high. Adding light urgency (limited quantity) can lift conversions further.

Back-in-stock best practices

Send promptly when stock returns, make the CTA one click to purchase, and consider flagging limited availability to encourage fast action.
