Sync Resend contacts during signup and before product-update sends, tagging contacts with customer_type=consumer and adding missing users to Resend's ALL segment (83f6138f-b7d1-418d-a0bc-10f3140abf8a).
Centralize Resend IDs in src/server/email/resendConstants.ts for Product Guides, Product Updates, and ALL segment.
Gate activation/consumer emails on Resend global unsubscribe + Product Guides topic (6897eea7-9fb5-4d99-8cf5-03511964cebd).
Add separate Product Updates broadcast code under src/server/email/broadcasts/, with the broadcast template moved to broadcasts/templates/broadcast-changelog-2-may-7.tsx.
Add /admin for @composio.dev users with broadcast email sidebar, product update list, preview send (1–2 emails), and send/schedule controls.
Keep the hidden admin-token API with ?preview support and ALL-segment sync before real sends.

pnpm lint currently fails on pre-existing unrelated repo issues (for example scripts/print-mcpjam-fixtures.ts console usage and src/components/attribution-capture.tsx raw fetch).

Product updates are keyed by PRODUCT_UPDATE_BROADCAST_KEYS in src/server/email/broadcasts/index.tsx.
/admin renders listProductUpdateBroadcastDefinitions() and submits the selected broadcastKey.
Current key: changelog_edition_2; adding future product updates means adding a new broadcast template and entry in PRODUCT_UPDATE_BROADCASTS.
