mail.send automation events can modify sent message drafts before they are delivered.
For instance, appending a unique survey link to only the sent html message (not text, nor the copy Cerb saves), setting custom fields, or adding custom mail headers to prevent Sendgrid from rewriting the Message-Id: header.
Content modifications can target any combination of text/html on the sent/saved message.
