How to customize Anspress notification email when there is a new question?

Hi everyone,
I am using Anspress as a Q&A system for my website, and want to customize the notification email every time someone posts a new question or gets an answer. The default email is very basic, but I want to:
Add the questioner’s name or question title to the subject for easy distinction,
Send in HTML format (with style, site logo),
Send notifications only to certain admins or moderators instead of all users.
I have searched in the Anspress code but do not know which file to start from to override templates, or is there a plugin that supports this?
I hope anyone who has done this before can share instructions or experiences.
Thank you very much!
