If you are not interested in extending the Web Hosting service, please follow this guide
If the domain is not paid for, it will not be renewed, and after the protective period expires, it will be automatically canceled (released for new registration). Due to the approaching expiration and potential cancellation, notification messages will be automatically sent to the owner's contact email regarding the need for renewal. However, if you do not wish to renew the domain, you can simply ignore these notifications.
If you do not wish to extend the Package service (domain + web hosting) or you are only interested in extending an individual domain, please follow the instructions in this guide
