  • Body : You can enter the body text either in the form of raw text or html in their respective fields.

  • Attachments : Attachments can be added to a SMTP query by referencing the file from the File Picker component in the attachments field.

    For example, you can set the Attachments field value to {{ components.filepicker1.file }} or you can pass an array of {{ name: 'filename.jpg', dataURL: '......' }} object to accomplish this.
