One of the bad features of Gmail is that it does text-mining on your emails and uses that information to surface targeted ads. That’s the price you pay for unlimited storage and a free service. This thought freaks out some people that Google is reading their mail. Especially true for business professionals and others who use email to transmit potentially valuable or sensitive information.

“We don’t scan your email content or attachments and sell this information to advertisers or any other company, and we don’t show ads in personal conversations,” Jones said.

Microsoft will not do text-mining on your inbox; while still offer its service for free and with virtually unlimited storage. Though, there will be right-column ads on the main inbox screen, but there aren’t ads on individual messages. Also, these ads are going to be targeted based on what Microsoft knows about you in general, just not on the content of your individual messages.
