Nothing is added, the domains are sold as-is.
In some cases, you may even have to renew the domain if it is expiring soon.
All our premium domain names are automatically managed, they will be renewed only when they are expiring in 30days and our system will not perform a renewal on a premium domain name once it is sold. We also do not provide any other related service such as email, hosting, etc. If you need hosting and email, you need to find those services on your own.
