Tuesday, 13 April 2010 Mail Alert is a free e-mail alert add-in for Microsoft Outlook. When new e-mail arrives, it will display a non-intrusive desktop alert containing essential information from the e-mail received. Now you can avoid the constant shuffle between work and e-mail, thus boosting your productivity. Want to reply to the incoming e-mail? No need to stop working and switch to your e-mail application; this program provides the most common actions directly from the desktop alert, such as reply, mark as read and delete.
