Using Claude Cowork in marketing operations to automate reporting and campaign building

Anthropic's marketing operations team shares how they use Claude Cowork to automate two major workflows: weekly marketing metrics reporting and event/campaign builds. Ian Chan reduced a 1-2 day weekly reporting process to ~2 hours using scheduled tasks, custom skills for report prep, proofreading, and Asana task creation. Annabel Custer automated end-to-end event setup across Salesforce, HubSpot, and other platforms using a dispatcher skill that routes requests to specialist skills, plus a separate audit agent for quality checks. The post includes practical advice: encode repeated corrections into skills, build a proofreading skill early, ask Claude to reflect on confusing instructions, and use scheduled tasks to eliminate manual triggers.
