What SaneBox does
SaneBox needs nothing installed: it judges importance from email headers and your habits, like which mail you open and answer. Unwanted senders go to BlackHole, a Daily Digest lists unimportant mail you have not opened, and Snooze hides mail until later. It works with Gmail, Microsoft 365, iCloud, Yahoo, Fastmail and any IMAP or Exchange server.
