About the startup
KeepKnown is an advanced filter builder for Gmail and Outlook. Combine relationship, history, header, attachment, subject, and mailbox signals with nested logic; preview rules on real mail; activate in Shadow, Review Only, or Enforce where supported; and trace every match in a decision log. New filters save paused, reusable templates speed up common workflows, and core filtering does not read email bodies.
