Let a domain expire
The domains are automatically deleted if they are not renewed.
You can deactivate the renewal notices by changing the renewal method to "Let expire". There are two options to do this:
From the domain management panel
Access the "Summary" section of the domain management, in the "Settings" column you will find the option "Renewal method" which allows you to configure it.
From the domain list
Go to the domain list ("Domains" -> "Domains") and click on the domain renewal method. A pop-up window will open with the available options.
If you want to assign the same renewal method to several domains at the same time, check the domain checkboxes, click on the button with 3 dots at the bottom of the page and then on "Renewal type". A pop-up window will open with the available options, the one you choose will be applied to the selected domains.
