The email address used for domain registration is not valid. Can it be changed?
The email address change for domains is done through the registrar. Written request for non-.ro domains, and for .ro directly in the ROTLD panel.
Email address modification can only be done through the domain registrar. For all extensions (except .ro), a written request will be required, submitted to office@hostico.com from the email address associated with the client account under which the domain was registered. For .ro domains, the update will be done directly through the ROTLD registry's administration panel.
