WooCommerce sends an email to the store admin every time an item is placed on backorder. There is no built-in toggle to disable this — the only options in WooCommerce → Settings → Emails control the email template, not whether it sends at all.
This plugin removes that notification cleanly, with no options page and no bloat.
What it does:
<ul>
<li>Prevents the “Product Backorder” admin notification email from being sent</li>
<li>Has no effect on any other WooCommerce emails</li>
<li>Does not affect the customer’s order confirmation or any other customer-facing emails</li>
<li>Works automatically on activation — no configuration required</li>
</ul>
Who is this for?
Store owners who use backorders as a standard fulfilment method and find the admin notification emails unnecessary or disruptive. If your warehouse team or fulfilment process handles backorders without needing an email trigger, this plugin removes the noise.
