@SaneBulk is an advanced feature folder that most users won't need. If your @SaneLater folder gets a lot of traffic, turning on @SaneBulk will give you some relief, allowing you to concentrate on the @SaneLater emails that might need processing.
Most of the folders you read are ordered by importance, meaning which folder you should look at first.
1. @SaneTop (a deprecated option, previously available to Gmail users.)
2a. @SaneNotSpam (Inbox-worthy email that we found in your Spam folder)
@SaneBulk is filled with mail that you shouldn't need to take action upon, so we think it is the least important. These emails are for reference. It includes email about when something shipped or Twitter follow notices from strangers. SaneBox's algorithm is somewhat nuanced though. For instance, a Twitter follow notice from someone important to you will be put in your Inbox.
Because email is really a forest of edge cases, we won't get this right every time. So, we send you a summary Message Digest of all these non-Inbox folders so you can teach us about things you'd rather see in your @SaneLater or Inbox folder. And you can always simply move an email into the correct Sane folder to teach us. The digest is also a great way to see what is in your Sane folders without needing to waste time looking in them.
We don't have an example list for exactly what goes into each folder because it is often situational and can change as your relationships change. And, the list would change as the SaneBox network learns better what the user base needs.
To turn your @SaneBulk folder on or off, go to your Sane Folders section of your SaneBox Dashboard. Expand the Advanced Filtering section to reveal those choices. Click the Show or Hide button for @SaneBulk to see the green indicator that confirms that you've turned it on.
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 also 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.
If you train an email to your Inbox, we will not move all of your emails to your Inbox. Only the recent ones. If you decide to enable SaneBulk, this can cause the older emails to then be sent to your Inbox.
