About KeepKnown

KeepKnown is an advanced filter builder designed for Gmail and Outlook, acting as the ultimate upgrade your native inbox filtering should have. Built to handle complex inbox organization, KeepKnown lets users combine relationship, history, header, attachment, subject, and mailbox signals using powerful nested logic.

Designed with security and testing in mind, core filtering does not read email bodies. Users can preview rules on real mail, trace every single match via a transparent decision log, and safely activate rules in Shadow, Review Only, or Enforce modes where supported. Additionally, new filters are saved paused by default, and reusable templates help speed up common daily workflows.
