Decoy is a free Chrome add-on designed to help users manage B2B sales emails in their Gmail inbox. By classifying sales pitches and scoring them against user-defined buying priorities, Decoy aims to reduce the noise created by unsolicited sales communications. The tool features color-coded badges next to emails, indicating their relevance, and provides detail panels that include vendor information and pitch types, allowing users to quickly identify pertinent emails without switching tabs.

The functionality of Decoy is straightforward. Users connect their Gmail account with read-only access, set their buying priorities, and the AI begins classifying incoming sales emails accordingly. The add-on also includes a feedback system where users can rate the relevance of emails, helping to refine future classifications. Emphasizing user privacy, Decoy ensures that no email content is stored or modified, maintaining control over personal data.
