    saveToSentItems: true,
    attachmentIds: [1012, 1013] // up to 10 attachments
  }

Notes

• When attachmentIds are provided, the system creates a draft, uploads the files, and then sends the draft — all in a single call.

• The IDs must reference attachments that still have accessible file data (either in DB or in external storage). If a blob was removed, update or re-upload the attachment.
