But even Gmail has its cons. It lacks thorough HTML email support, both for viewing and composing. It lacks some common features in other email services, such as a choice of spam filter level, the ability to trash messages easily and also doesn't work well (works only in plain HTML mode) with Opera and other older browsers.
Also there have been 2 privacy issues raised with Gmail. Firstly, the unobtrusive and generally clean looking ads on the right of most pages are contextual. This means these ads are generated based on page content, or in this case email content. Therefore every time you view an email, you're email content is analyzed and then converted into ads for Google's revenue. According to Google, this is all done by robots not humans, and therefore the email is never read by any humans, but none the less, many users get freaked out when they see their email posted in ad-form on the right of the screen.
