Alternative(text) sets the text/plain part of a multipart/alternative message, so a client that shows no HTML reads the same words. The SMTP provider fills email.Text beside email.HTML; Twilio's Emails API takes it as content.text beside content.html. A plain-text body is already that part and is unchanged.
