Gmail uses Google search technology to automatically organize and find messages. And because Gmail includes 1,000 megabytes of storage, a typical user won't ever have to worry about deleting mail. Everything just gets archived so it can be found again if needed.
There are other differences in the way Gmail provides access to your email. For example, Gmail automatically groups an email and the replies to it as a conversation. That means you always see a message in its proper context. And there are no pop-ups or banner ads in Gmail, just relevant text ads and links to related pages. Gmail's other distinctive features include a labeling system, a spam reporter and a system for filtering your mail as it comes into your inbox.
