This is quite an uncommon WooCommerce requirement, but especially for downloadable products the Completed Order email is such as important one – and customers may end up asking you to resend them all their past order emails.
This is an interesting snippet, as it features important functionalities: getting orders by billing email, looping through the results and re-triggering the Completed Order email whenever a specific admin URL parameter is posted. Enjoy!
