## Twenty for Twenty: Resend module Introduces `packages/twenty-apps/internal/twenty-for-twenty`, the official internal Twenty app, with a first module integrating [Resend](https://resend.com). ### Breakdown **Resend module** (`src/modules/resend/`) - Two app variables: `RESEND_API_KEY` and `RESEND_WEBHOOK_SECRET`. - **Objects**: `resendContact`, `resendSegment`, `resendTemplate`, `resendBroadcast`, `resendEmail`, with relations between them and to standard `person`. - **Inbound sync (Resend → Twenty)**: - Cron-driven logic function `sync-resend-data` (every 5 min) pulling all entities through paginated, rate-limit-aware utilities (`sync-contacts`, `sync-segments`, `sync-templates`, `sync-broadcasts`, `sync-emails`). - Webhook endpoint (`resend-webhook`) verifying signatures and handling `contact.*` and `email.*` events in real time. - `find-or-create-person` auto-links Resend contacts to Twenty people by email. - **Outbound sync (Twenty → Resend)**: DB-event logic functions for `contact.created/updated/deleted` and `segment.created/deleted`, with a `lastSyncedFromResend` field for loop prevention. - **UI**: views, page layouts, navigation menu items, and front components (`HtmlPreview`, `RecordHtmlViewer`) to preview email/template HTML in record pages; `sync-resend-data` command exposed as a front component. ### Setup See the new README for install steps, webhook configuration, and local testing with the Resend CLI.

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
