Use modular templates, a proof bank, light governance, and a single source of truth, then QA like a GTM asset.

Consistency is a system problem. Build modular messaging blocks (role promise, proof bullets, fit signals, process) and store them in one place. Embed them into ATS/CRM templates and interview kits. Assign an owner to maintain the proof bank and update quarterly. Add lightweight QA: spot-check job posts and outreach, and review interview kits during hiring kickoffs. Treat it like GTM: consistency increases conversion and reduces risk for candidates.
