Ever wake up with an inbox full of Facebook emails? Annoyed by newsletters you're not going to read anyway? Going through all of them just to get rid of the red badge just takes too much time. This is why we invented Mark Read, an easy way to mark either your entire inbox or just the emails you want as read/unread, right within Mail.app.
Just tap 'Edit' in your mailbox, select the mails you want to mark as read/unread and tap 'Mark' in the upper left corner. If you want to mark the entire mailbox as read/unread, tap 'Mark All'.
If you enjoy Mark Read, check out other CocoaNuts tweaks like YourTube 2, YourTube HD and Safari Download Manager
