From the developer:
MailBar enables you to check your inbox and manage your emails directly from your Mac's status bar.
The light and discreet application is designed to run in the background and display the number of new emails next to its menu bar icon. Thanks to MailBar, you can monitor and manage up to four different mailboxes. From MailBar's status bar menu you can easily view all existing emails or filter the list by showing only the unread messages.
