# Send Email - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/email

Language: en

Queues an email via SMTP. Addresses, subject and body support expressions. Use the visual mail builder or edit HTML/CSS directly.

## Usage and specifics

Select an SMTP credential. Build the body visually or with HTML/CSS. Addresses and subject accept expressions; the schema limits attachments to 10.

Technical type : `email`. Runtime : `nodulz`.

## Credentials and prerequisites

- [Create and configure the credential : smtp](/docs/credentials/smtp)

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the [credentials guide](/docs/credentials) for access and rotation.

## Parameters

## Configuration help

| Setting | Purpose and guidance |
| --- | --- |
| `to`<br>To | Use double curly braces for dynamic values, e.g. {{ nodes.http1.body.id }} |
| `from`<br>From | Optional - defaults to the SMTP credential user. |
| `replyTo`<br>Reply-To | Use double curly braces for dynamic values, e.g. {{ nodes.http1.body.id }} |
| `cc`<br>Cc | Use double curly braces for dynamic values, e.g. {{ nodes.http1.body.id }} |
| `bcc`<br>Bcc | Use double curly braces for dynamic values, e.g. {{ nodes.http1.body.id }} |
| `subject`<br>Subject | Email subject - workflow expressions allowed. |
| `credentialId`<br>SMTP server | Select a saved SMTP credential from the Credentials page. |

## Examples

- To: {{ input.email }}
- Subject: Order {{ input.orderId }} confirmed
- Mail builder: drag blocks or input fields, insert merge tags, then Apply.
- Body: design in the mail builder, or HTML with {{ input.name }}.

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "to": "",
  "subject": "",
  "body": "",
  "bodyCss": "",
  "bodySource": "html",
  "bodyBuilderProject": ""
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
