Having your unimportant emails automatically moved from your Inbox into another folder is strategic. It helps put a stop on unwanted distractions. Those unwanted interruptions are moved into your @SaneLater folder for you, right inside your own email account.
Emails in your SaneLater folder are summarized in your SaneBox Digest.
And if an email in your @SaneLater folder is from a sender you’d rather see in your Inbox, you can easily teach SaneBox by using your email app to **Move an example item for that sender back to your Inbox.
By default your SaneBox Digest is sent to you once each afternoon. You can customize your digest schedule from the Account Settings section of your dashboard, to receive this summary digest of new unimportant emails more often.
And, the digest web appsection of your SaneBox Dashboard (the emailed digest links to it) gives you even more powerful and direct access. It’s a very efficient way to bulk-process your lower-priority mail later.
Extra: For Yahoo users, here’s a help page they provide that includes pointers for using mail folders.
