My Opera Mail is a free web-based e-mail service by Opera. It features a fast, elegant and effortless to use interface.
All related e-mails are grouped into 'conversations', so you can read all the replies at once. It features strong spam protection to keep the junk e-mails out of your inbox. The elegant design puts your e-mail on center stage, with a fresh, clean look and no flashy ads. The service offers users 3GB of mail storage and can be freely accessed via IMAP. More Info »
The webmail interface should be familiar to Gmail users, however it features no contextual ads. In other words, Opera Software doesn't automatically scan e-mails to add context-sensitive advertisements, meaning reasonable respect of privacy.
The webmail is tightly integrated with the My Opera social network.
