A full-featured Mailchimp integration that surfaces 18 core tools plus conditional asset and template management. You get campaign CRUD with single-call send workflows that request human confirmation before firing, subscriber upsert with declarative tag sync, batch imports capped at 500 rows, audience and segment management, merge field config, and post-send analytics sliced ten ways. The two workflow helpers handle the common "draft content, run checklist, send or schedule" and "clone last week's campaign with tweaks" patterns end-to-end. Local asset references in HTML auto-upload to Mailchimp's CDN. Local template authoring via Eta gives you a proper write path on free-tier accounts where the upstream templates API is read-only.
