Ah, not a typo but I can see how that's confusing for people who mark things read vs unread instead of archiving vs leaving in the inbox. GmailZero only works

Ah, not a typo but I can see how that's confusing for people who mark things read vs unread instead of archiving vs leaving in the inbox. GmailZero only works for people who (try to) diligently archive messages. It doesn't count Unread messages against you since you don't have control over those.
