I would question whether the user needs two badges.
Allow me to make some assumptions as you have not provided details of how the information meets user needs.
Does the user need to know there are escalated messages or how many there are? Which is more important?
Presumably if there are ANY escalated messages, the user will go to the inbox sooner. I don't imagine it's a case of the user saying, "Oh, there are only 3 escalated messages. I'm not going to check out the inbox now. If there were 4, I'd go immediately to the inbox."
It seems the NUMBER of escalated messages is immaterial to the user's decision to act and is therefore clutter. What matters is that there are ANY escalated messages.
So, what the user really needs to know is:
- There are messages (the number gives some indication of how much time the task of checking messages will take me to handle)
- Some are escalated (presumably these would be a
the top of the inbox)
I would therefore have one badge showing total messages, and vary the treatment somehow when some of those messages are escalated. Color, shape, position and size are typical ways to show the difference between the escalated and non-escalated states.
