Interestingly, one of my biggest problems with Gmail is that they don't allow actual plaintext. I used to routinely collaborate with developers who were vision-impaired, and the official Gmail phone app wouldn't let me send them plaintext email. Instead, it was some sort of HTML thing. Unfortunately, we sometimes sent code snippets to each other over email, and though admittedly it looked more or less fine, Gmail changed the underlying representation enough that my collaborators' screen readers would mess up on the parsing.
This led to me leaving Gmail on my phone, which led ultimately to me leaving Gmail entirely.

But the noun "herald" literally means "official who tells the news"
So this still definitely checks out.
