Inbox emails are the emails that you need to deal with now.
SaneBox adds new folders to your email account (along side or nested under your Inbox) and we work with your email server through requests to move your unimportant emails into these other Sane folders to be checked at your leisure.
This makes your Inbox less full so that you don’t have to search through unimportant emails and possibly get side-tracked from what really matters to you most.
