Customer Marketing Campaigns — Marketing aimed at the accounts you already have — feature adoption pushes, tier-upgrade promotions, event invitations — rather than net-new logos. Campaigns segment on billing and usage data via reverse ETL and warm the ground for expansion scoring's targets.
Customer Marketing Campaigns lives in the Expansion Channels phase of Grow Revenue — the stage where you retain, expand, and compound revenue on the platform. In the corpus tool index this phase maps to the Billing and CRMcategories.
