In the easyLabel UI, we provide an option to make a fulfillment within the app and send a notification for a fulfillment. These notifications are sent using Shopify's notification feature and can be configured in the "Shipping Confirmation" section.
Currently, there is an option on Japan Post international mail my-page where users can configure Delivery status email settings. This setting allows for Japan post to send emails to the sender of the package and the receiver of the package for the further information.
easyLabel does not have any feature related to these notifications above, and if you would like to use these settings to ensure the sender or the receiver of the package receives these mails, please use the Japan Post international mail my-page and generate the labels manually.
