This node requires an Email (SMTP / IMAP) credential. To create a credential:

Go to Settings → Credentials → New Credential
Select Email (SMTP / IMAP)
Enter your SMTP username, password, host, port, and encryption

Use Cases

Order Confirmations: Email receipts and invoices after a purchase

Email Format

Format	Behavior
`HTML`	Sends only the HTML body
`Text`	Sends only the plain text body
`Both`	Sends both HTML and plain text; the recipient’s client decides which to display

Attachments

Each attachment supports:

Field	Required	Description
Attachment Type	Yes	Choose `Link` for an existing URL or `Upload File` to upload a file directly
File URL	Yes	Public URL for link mode. In upload mode, this value is set automatically after the file is uploaded
File Name	No	Name shown in the email, e.g. `invoice.pdf`. When omitted, the node derives it from the URL

Uploaded files stored by SubverseAI are resolved to a temporary signed URL when the email is sent.

Output Data

A successful send returns:

{
  "messageId": "<[email protected]>",
  "response": "250 OK",
  "accepted": ["[email protected]"],
  "rejected": []
}

Reference in downstream nodes:

{{ sendEmail.messageId }}
{{ sendEmail.accepted }}
{{ sendEmail.rejected }}

Common Patterns

Attach a File by URL

HTTP Request or upstream node (returns a file URL)
  ↓
Send Email (Attachment Type: Link)

Map the attachment File URL to the upstream URL. You can leave File Name blank to derive it automatically from the URL.

Upload and Attach a File

Choose Upload File in the attachment, then drag and drop or select the file. The uploaded file URL is populated automatically.

Send AI-Generated Follow-up

AI Agent Node (generate email subject and body)
  ↓
Send Email (subject and body linked from AI Agent output)

HTTP Request — Fetch files or data to include in an email
SubVerse Agents — Hand off email conversations to an AI agent
Conditions — Branch based on send success or failure

Link the Subject, HTML, and Text fields from an upstream AI Agent node to generate personalized, context-aware emails.

For Gmail and other providers with app-specific passwords, use the app password in the credential, not your regular account password.
