I don't want email messages with, inline pictures, colours, and links that obscure their target. (I also don't want emoji.) Tables can still be made in plain text if necessary. (I use a email client that does not even support HTML email, so it is displayed as plain text anyways. If you send it as both (which some programs do), then it can be possible to configure the client (if it can be configured as such) to display it as plain text.)
Tables can't be made in plain text, they'll break on reflow (very common in this day and age to have devices of various widths), also it's harder to do tables by hand
Sending as both: what happens to clients that can't be configured as such?
