Since Jan 1, 2014, ICANN requires e-mail verification of the contact details. If you change the contact details of an existing domain name, start a transfer or register a new domain name, verification e-mail will be send to the domain administrative contact from e-mail sales@cloudns.net and confirmation link need to be opened to confirm your e-mail. The confirmation link will be active for 15 days, if the contacts are not verified the domain name will be deactivated (the name servers will be changed) and you will need to contact us to activate your domain name again. After the confirmation, no more verifications will be required for this e-mail and it can be used for other domain names. Please keep your contact details correct.
Regards,
