@PitaJ and who else may encounter this issue, here is how I solved it.
The root problem was the image format used for "Site Logo" in general/settings.
I've uploaded a png file and the information was not saved in the database, althoughthe fields remained filled across the sessions.
Once I've changed the site logo with a jpg file, the emails were properly formatted too.
@PitaJ said in email notifications for post queue:
Just so everyone knows, there's a search bar in the ACP, that searches the ACP. If you're looking for a setting that may be a good place to start.
Oh, I've never seen that. It's in all that "Dead space" way up top that I scroll past before it even loads because there is so much wasted space. Good to know that that is there.
Would be nice to see that area compressed a bit, so much empty space up there.
