Can't edit the text version of the new emails in this system. The text versions STINK. Yes, people still do see the text version sometimes. Now there is no way to push them to view the mail as a webpage.
Because of increased security considerations, those we are sending to that have email addresses from the government, military, contractors and law enforcement have servers that completely convert all the html and images in the email into code (like the below) so the receiver has to search through all the coding to find our message. Yes plain text is boring but this is the new reality about cyber security these days.
