Scroll down to the Domain names section, and click on the Domain auto renewals link.
This will open your Domain renewal settings page, where you can choose the auto-renewal status of your Domain Names.
You can select the renewal period of your domain names using the dropdown box provided, and set your domains to renew for a period of up to 10 years.
Ensure that the renewal status for each domain name is set to On for the ones you wish to renew.
If you would like particular domain names to not renew, simply use the toggle to set the renewal status to Off.
You can also manage your auto-renewal status in bulk by using the tool at the bottom of the page.
