Transforms message to Email Message by populating email fields using values derived from Message metadata. Set ‘SEND\_EMAIL’ output Message type that can be accepted later by [**Send Email Node**.](https://docs.tesenso.com/tesenso-iot-cloud/rule-engine/rule-engine/output-connectors/send-email) All email fields can be configured to use values from metadata.

For example incoming message has **deviceName** field in metadata and email body should contain its value.

In this case value of **deviceName** can be referenced as `${deviceName}` like in the following example:

```javascript
 Device ${deviceName} has high temperature
```

Additionally this node can prepare email attachments if incoming message metadata contains **attachments** field with reference to files stored in DataBase.
