I get a daily newsletter from Audible.  They include both plain text and html versions of the message, but only the plain text option includes the name of the book (in the html version it is part of an image).  Since I'd rather not download images and activate the trackers, I typically view the source of the message to see the books title and author info.

Is there a way to tell the mail client (website version here), to show the plain text version for a particular sender?

MailMate, my normal mail client does this, but I find myself using the web more often these days.

Thanks
