Back in Stock

Ayra Back in Stock is a Shopify restock alert module that captures variant-level demand and sends alerts by email, SMS, WhatsApp or web push when inventory returns. Because it shares the customer profile, VIPs and high-intent customers are notified first and alert volume is capped per customer.

Restock alerts prioritised by who's actually likely to buy.

01 What it does

What Back in Stock does

  • Email, SMS, WhatsApp and web push

    Customers choose the channel. Ayra sends the alert where they asked for it.

  • Variant-level alerts

    Alerts are tied to the exact size and colour, not just the product, so customers only hear when their variant is back.

  • Waitlist size per product

    See how many people are waiting on each product and variant, and use it when planning restocks and merchandising.

  • Priority send to VIPs and high-intent customers

    When stock is limited, VIPs and high-intent customers are notified first, using tier and intent data from the profile.

  • Pre-order handoff

    When a restock date is known, the alert can offer a pre-order instead of a wait.

  • Alert cap per customer via Journey Guard

    A customer waiting on ten items does not get ten emails in a morning. Journey Guard caps and spaces the alerts.

05 FAQ

Back in Stock questions

Which channels can send restock alerts?

Email, SMS, WhatsApp and web push. Customers pick their channel when they sign up for the alert.

Are alerts per variant or per product?

Per variant. A customer waiting on a medium is only alerted when the medium is back.

Who is notified first when stock is limited?

VIPs and high-intent customers, based on tier and Intent Engine scores from the customer profile.

Can a restock alert turn into a pre-order?

Yes. When you set an expected restock date, the alert offers a pre-order instead of a wait.
