# Compose and send Broadcasts with the API
> Send marketing emails using the Broadcasts API.
Resend's [no-code Broadcast editor](/docs/dashboard/broadcasts/editor) allows all members of your team to write and send email campaigns directly in the Resend Dashboard, without having to ask for help from developers.
To programmatically create, update, and send Broadcasts, you can use the [Broadcast API](/docs/api-reference/broadcasts/create-broadcast). There are also API endpoints to list, retrieve, and delete Broadcasts, allowing you to manage your marketing campaigns directly from your application.
## Create Broadcasts
The [`create()` method](/docs/api-reference/broadcasts/create-broadcast) takes the same sending properties that can be set in the Editor composer. This allows developers to also create drafts without sending, schedule sending for a time in the future, [personalize with dynamic content data](/docs/dashboard/broadcasts/editor#personalize-your-content), and more.
Set the `send` property to `true` to send immediately or to schedule the Broadcast, or leave `false` (the default) to create a draft:
```ts Node.js theme={"theme":{"light":"github-light","dark":"vesper"}}
import { Resend } from 'resend';
const resend = new Resend('re_xxxxxxxxx');
// Create a draft Broadcast
const { data, error } = await resend.broadcasts.create({
segmentId: '78261eea-8f8b-4381-83c6-79fa7120f1cf',
from: 'Acme ',
subject: 'hello world',
html: 'Hi {{{contact.first_name|there}}}, you can unsubscribe here: {{{RESEND_UNSUBSCRIBE_URL}}}',
});
// Create and send immediately
const { data, error } = await resend.broadcasts.create({
segmentId: '78261eea-8f8b-4381-83c6-79fa7120f1cf',
from: 'Acme ',
subject: 'hello world',

## Send Broadcasts
Use the [`send()` method](/docs/api-reference/broadcasts/send-broadcast) to send or schedule an existing API-created Broadcast by ID. Broadcasts created using the Dashboard Broadcast editor cannot be sent with this endpoint.
```ts Node.js theme={"theme":{"light":"github-light","dark":"vesper"}}
import { Resend } from 'resend';
const resend = new Resend('re_xxxxxxxxx');
const { data, error } = await resend.broadcasts.send(
'559ac32e-9ef5-46fb-82a1-b76b840c0f7b',
{
scheduledAt: 'in 1 min',
},
);
```
```php PHP theme={"theme":{"light":"github-light","dark":"vesper"}}
$resend = Resend::client('re_xxxxxxxxx');
$resend->broadcasts->send('559ac32e-9ef5-46fb-82a1-b76b840c0f7b', [
'scheduled_at' => 'in 1 min',
]);
```
```py Python theme={"theme":{"light":"github-light","dark":"vesper"}}

## Other ways to send
You can also send and manage Broadcasts using [Resend CLI commands](/docs/cli#broadcasts) and [AI building tools](/docs/ai-onboarding).
