Marketing/campaign emails on top of the emailing-domain (SES) feature:
send a broadcast to a hand-picked list, with per-customer-domain
unsubscribe links and opt-out-only **unsubscribe topics**.
## Model
Standard objects (workspace schema, flat-metadata):
- `messageCampaign` — a campaign send (subject, body template, from
address, status, list, optional unsubscribe topic).
- `messageList` + `messageListMember` — the hand-picked audience (person
↔ list join). A campaign's recipients are its list's members; everyone
is sendable unless suppressed.
Core entities (`core` schema, workspace-scoped — readable by the public
unsubscribe flow without a workspace context):
- `unsubscribeTopic` — an opt-out-only category (name, description,
visibility). There is no opt-in subscription state.
- `messageSuppression` — the single consent store: a row with
`unsubscribeTopicId` NULL is a global block; a row with an
`unsubscribeTopicId` and reason `UNSUBSCRIBE` is a per-topic opt-out.
Two partial unique indexes dedupe global vs per-topic rows (Postgres
treats NULLs as distinct).
- `emailingDomain` — the workspace's SES sending domain,
auto-provisioned when an email channel is added (and cleaned up when its
last channel is removed), with verification status + DNS records.
Campaign messages reuse the existing `message` / `messageThread` /
`messageParticipant` model — one outbound `message` per recipient with a
`deliveryStatus` state machine.
## Sending
- `sendMessageCampaign` resolves the audience **under the caller's
permissions**, creates the campaign, and enqueues a single fan-out job
(the request never materializes per-recipient rows or jobs).
- The fan-out job materializes one QUEUED message per recipient
(deterministic ids → idempotent re-runs, reconciles crash-orphaned rows)
and fans out per-recipient send jobs carrying **only ids**.
- Each send job renders per-recipient `{{variable}}` merge fields and
sends via `EmailingDomainSenderService`, which applies suppression
(global + per-topic) and the unsubscribe footer/headers. Suppressed
recipients are recorded `SKIPPED`.
- The campaign finalizes `SENT`, or `SENT_WITH_ERRORS` if any recipient
terminally failed.
- `previewMessageCampaignAudience` returns a pre-send breakdown (total /
without-email / duplicate / globally-unsubscribed / topic-unsubscribed /
sendable), shown as a hint under the composer pickers.
## Unsubscribe
- Encrypted (AES-256-GCM) token carrying workspaceId, address, optional
`unsubscribeTopicId`, `issuedAt`, and a `preview` flag.
- One-click POST (RFC 8058) + `mailto:` — topic-scoped when the token
carries a topic, global otherwise.
- Preferences page: a checkbox per visible topic (checked = still
receiving); submitting creates per-topic opt-outs for unchecked topics
and lifts re-checked ones (UNSUBSCRIBE only — never
`BOUNCE`/`COMPLAINT`, never a global block).
- A **Preview** action in settings opens the live page via a
preview-claim token; opt-out POSTs are no-ops for preview tokens, so
previewing never mutates state.
- SES webhooks: inbound unsubscribe + outbound bounce/complaint →
suppression (race-safe against at-least-once delivery, with reason
escalation that never downgrades).
- Per-customer unsubscribe hostname (Cloudflare DNS); sends are gated on
it being active, except in LOG/demo mode.
## Architecture
Campaign orchestration, suppression, the sender, the unsubscribe
controller, and the SES webhook handlers live in `src/modules/emailing`
+ `src/modules/messaging-webhooks` (the workspace-feature layer).
`core-modules/emailing-domain` keeps the SES driver, domain
provisioning, the `unsubscribeTopic` / `messageSuppression` core
entities, and the unsubscribe token/hostname plumbing. Domain creation
is validated (`CreateEmailingDomainInput` — domain-format regex,
lowercased) before any value reaches SES or the unsubscribe hostname.
## Frontend
- Campaign composer side panel (from / list / unsubscribe topic /
subject / body) with a live audience-preview hint.
- Email settings: email channels each showing their auto-provisioned
sending domain in a single section (status + DNS records + a "Check
verification" action), plus an **Unsubscribe Topics** section to
create/manage topics and preview the recipient page. A demo-mode banner
is shown when the LOG driver is active.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
