This is certainly a valid concern of many first time SaneBox users. We have tried to alleviate it in a number of different ways.
1. By default, once a day between 2:00-5:00 PM, SaneBox sends you a digest of all your new, unread unimportant emails. This gives you a quick mechanism to determine if there is anything crucial in your SaneLater or other optional Sane folders. Your first digest will include all unread emails in your SaneLater folder from the past 15 days.
- In general, you should find that your Inbox holds the emails that should interrupt you while @SaneLater holds emails that can wait.
