Email body text is read from the email_body.txt or file defined by EMAIL_BODY environment variable if either exists. File content can include <ATTACHMENT_TEXT> text which will be replaced with the text information the filename of the attachment.
Robot Framework IF/ELSE syntax is in use to make process more readable.
