Email (Automations, etc) triggered by category

Hi! Do you ever plan to offer more capabilities for the newsletter emails (campaigns, recurring newsletters, etc.) ? For example, if I have Group A and I only want them to see posts from specific categories, events, or custom meta, there is currently no option to set this up to trigger based on anything other than a core meta in general and a restrictive timeframe. See screenshots.

I want to choose a post category, or job category, or any other meta so that the email is only triggered if new content from that meta is posted. Group A may not want to receive the same newsletter content as group B. Does that make sense?

Maybe I am looking at this wrong or just missing some info. Please advise. Thanks.
