How many emails do you have in your inbox? More to the point, how many of them are sitting there waiting for you to add an event to your calendar before being tucked into a folder or trashed? If the answer is “way too many”, a new email app might actually help. Called SlideMail, the app is meant to help bad email actors efficiently sort through their digital mail. With a bit of time, SlideMail actually learns how you react to email, and encourages better habits.
