Summary

Send a new email through the configured SMTP server, with optional CC/BCC recipients and binary attachments. By default, also append a copy to the IMAP Sent folder.

Inputs

  • From — Sender address or formatted name and address. Leave empty to use the credential’s default From address; execution fails if neither is set.
  • To (required) — Recipient addresses separated by commas or semicolons.
  • CC — Optional CC addresses separated by commas or semicolons.
  • BCC — Optional BCC addresses separated by commas or semicolons.
  • Subject (required) — Email subject.
  • HTML Body — Optional HTML content.
  • Plain Text Body — Optional plain-text content. If omitted, the mail composer may derive it from the HTML body.
  • Attachments (Binary Property Names) — Comma- or semicolon-separated names of binary properties on the input item. Each is attached using its binary filename and MIME type when available.
  • Save Copy to Sent — Defaults to true. When enabled and IMAP is available, appends the sent message to the Sent folder and marks it seen.
  • Sent Folder Override — Optional IMAP folder path used for the saved copy. If empty, uses the credential’s manual folder setting, detects a Sent folder, or falls back to a conventional folder name.

Output shape

One output item per input item, containing an email send result record.

The record includes messageId, accepted and rejected recipient lists, and smtpResponse. When saving to Sent succeeds, it also includes savedToSent with the folder path and appended message UID (which may be null). With Continue On Fail, an item that errors instead returns {"error":"..."}.
