Problem
Teams repeat the same headers, footers, legal blocks, PS, and promos across many emails. Updates are manual and error-prone.
Proposal
Add Sections to Emails (parity with Websites/Funnels):
Global Sections: single source of truth; edits sync to all emails using them.
Local Sections: detached copies editable per email.
Template Sections: saved blocks for quick insert (no auto-sync).
UX
New “Sections” library under Marketing → Emails.
Insert panel: Global / Local / Template tabs.
Badge + tooltip shows section ID and last updated.
“Convert to Local” and “Re-link to Global” actions.
Controls & Safety
Draft → Publish workflow for Global updates.
Scoped permissions (view/use/edit/publish).
Version history with one-click rollback.
Dependency list: where a Global Section is used.
Tech Notes
Section entity with type, content_json, version, usage_map.
Rendering resolves Global by section_id at send/build time.
API: CRUD for sections; bulk re-link; diff preview.
Benefits
Consistency, faster production, fewer compliance misses.
Success Metrics
↓ build time/email, ↓ content drift, ↑ reuse rate.
