Establish and maintain segmented, up-to-date communications and distribution lists organized by audience (e.g., partner leadership, legislative contacts, institutional analysts, media, public subscribers). Define ownership, update cadence, and quality standards for each list. Ensure lists are ready to support rapid product releases, announcements, and targeted outreach aligned to the stakeholder outreach plan (1.3.1.2) and release communications plan (1.3.1.3).
