Opera Mail is a lightweight mail client. This means that if you have a POP3, IMAP enabled account, you can use it on your desktop through this application to read your email. Services like Gmail offer users the possibility to read their emails on their computer straight from the desktop with the help of these applications without the need to open a browser.
Install the application, configure an account with POP3 or IMAP and then you'll be able to send and receive emails on your desktop computer.
