Mail Sentinel scans your email bodies (not subjects) for three things: 1) Emails containing both a username and password, 2) Emails with the word "unsubscribe" and extracts the unsubscribe link, 3) Mailing lists grouped by sender with their unsubscribe links.

Mail Sentinel requires macOS 11.0 (Big Sur) or later, Apple Mail app with at least one email account configured, and approximately 50MB of disk space. Works on both Intel and Apple Silicon Macs.
