Is it possible to obtain an e-mail address like [email protected]
If you became an Ubuntu member you get the benefit of an @ubuntu.com email.

Ubuntu members are people who are helping the development and growth of Ubuntu. It does not require coding or packaging. You can be an Ubuntu member by just contributing to translations or marketing.
By just using Ubuntu it is not that easy to get an email address.
