Spam Filters: Reviews

ClearMyMail filters email before it ever reaches the user's inbox. Since it doesn't need to be installed directly onto a computer, it works with any operating system including Windows, Mac and Linux as well as portable… devices like smartphones and BlackBerry phones. According to the manufacturer, mail is filtered 18 ways before being sent on to the recipient. ClearMyMail does require some set-up time, but reviews are consistently positive. ClearMyMail rates particularly high for its low false-positive rate, meaning there's less risk of legitimate emails being blocked.
