Option to send only text/plain email notifications
Please, make it possible to send only text/plain notifications, not text/plain + text/html. The thing is that the information is doubled in the notifications, while I do not care of fancy fonts or whatever, I care of the information itself, thus I'd prefer to be able to receive only text/plain notifications. I didn't find any option for it.
I'm raising this due to GNOME is going to use gitlab, moving away from bugzilla, where one could choose what fits him/her the best, but gitlab doesn't offer any such option (or I didn't find it). As I said, for me personally, there is no need to have used more than twice more space on the disk for a notification of some change. You ahve all the code already there, thus it shouldn't be that hard to add the option, I suppose.
Thanks for consideration.
Note I noticed the issue about the text/plain not containing that much information as text/html, but that: a) is okay, b) has no impact as soon as you fix that issue as well.
