> Introduction to automated cadences

## What are Cadences?

Cadences are automated message sequences that are sent to leads at defined intervals.

## Use Cases

<CardGroup cols={2}>
  <Card title="Onboarding" icon="handshake">
    Welcome sequence for new leads
  </Card>

  <Card title="Follow-up" icon="reply">
    Automatic follow-up after contact
  </Card>

  <Card title="Nurturing" icon="seedling">
    Content sequence for engagement
  </Card>

  <Card title="Re-engagement" icon="rotate">
    Reactivate inactive leads
  </Card>
</CardGroup>

## Cadence Structure

A cadence consists of:

1. **Name and description** - Identification
2. **Steps** - Ordered messages with intervals
3. **Triggers** - Conditions to start/stop

## Step Example

```json theme={null}
{
  "order": 1,
  "delay": "P1D",
  "message": {
    "type": "text",
    "content": "Hello {{LEAD_FIRSTNAME}}, how can I help you today?"
  }
}
```

## Delay Format (ISO 8601)

| Format  | Description |
| ------- | ----------- |
| `PT30M` | 30 minutes  |
| `PT2H`  | 2 hours     |
| `P1D`   | 1 day       |
| `P1W`   | 1 week      |
| `P1M`   | 1 month     |

* `{{LEAD_NAME}}` - Full name
