The folks at SaneBox have created a technical solution that sorts the urgent from the unimportant and keeps time-critical messages at the top of your inbox.
Looking for an easy way to organize the e-mails in your overflowing inbox? SaneBox uses an algorithm to determine which messages are important and which ones can be saved for later.
SaneBox has appealing extras. One example: It double-checks your spam filter. If it spots a message that looks legitimate, it plops the e-mail into a "not-spam" folder.
