By default, SaneBox enables two Sane folders, your Inbox and @SaneLater. Your Inbox includes email you should look at soon, and @SaneLater includes email you should look at when you have some spare time.
If you prefer, you can enable another folder, @SaneTop, that will contain only your most important email. These are emails you should look at ASAP. Note: @SaneTop is only available to Gmail users. Additionally, SaneBox can put your very least important mail that you only need to look at as a reference in a folder named @SaneBulk. @SaneNews is a folder that holds newsletters and other mailing lists. If you prefer, you can also create a Custom Filing Folder, and anything you train to that folder will be delivered there automatically.
SaneBox can also create a few folders that you use instead of read. @SaneBlackHole allows you to train senders directly into your Trash. @SaneReminders will send you a reminder if you haven't received a response from a particular email or if you would like a reminder at a particular time. @SaneTomorrow and @SaneNextWeek will remove your emails from your Inbox until tomorrow or next week so they won't clutter your Inbox. You can also create a Custom Defer Folder if you prefer this feature for a different length of time.
When you enable or disable a Sane folder, there will be a small delay of 5-30 minutes before your changes take affect. During this time, your Inbox may become messy while emails are being relabeled. Don't worry, your trainings will not be forgotten during this time! After waiting a few minutes, you may need to restart or resync your email application in order to see the changes. Some email clients may require you to resubscribe to your selected IMAP folders.
