* **Limit Wait Time**: Whether the workflow will automatically resume execution after a specified time limit. This can be an interval or a specific wall time.
* **Append n8n Attribution**: Set whether to include the phrase `This email was sent automatically with n8n` at the end of the email (turned on) or not (turned off).

### Limitation

The Send Email (SMTP) node does not support setting headers like In-Reply-To and References, which are required for email threading. As a result, each email is treated as a new conversation instead of appearing in the same thread.

* **Workaround**: Use the Gmail node’s Reply operation or a custom node (e.g., n8n-nodes-better-send-mail) that supports custom headers.
