As Thede described earlier, at it’s root, Boxbe is designed to protect your most valuable asset: your attention. While you might not think of your time as being valuable, imagine how you might spend your time rather than deleting unwanted email. The mind abounds with activities that are more fun and rewarding.
Sounds great, how does it work?
Nuts and bolts
Once you’ve joined Boxbe, you decide who can reach you by first uploading a list of pre-approved senders.

We’ve made it easy by integrating an email address import tool for your contacts from many different email providers and popular email applications.
When new people email you, depending on your preferences, they are sent a courtesy notice with the option of taking a test to prove that they are human or paying a fee to talk to you.
Non-humans (automated emails) won’t be able to reach you without paying a fee or being approved by you. When a sender takes a test or pays, you can approve them by simply clicking on the link in their message. Alternatively, you can visit your quarantine folder and approve them.

That’s it.
Boxbe sends you a periodic update telling you about the messages in your quarantine, so you’ll know if there is any email that you are missing. In addition, you can review your quarantine to approve new senders at any time.
