Wordpress plugins for multiple category-specific newsletters

Title probably isn't clear - what I'm searching it's a plugin for opt-in and for letting users sign in to newsletters, but letting them sign in also to a specific category - let's say a website is divided into programming and web design, I make a taxonomy with programming category and web design category and in the first category I put a form for letting them subscribe only to a programming newsletter, and same for the second category.
Don't know what to search honestly, hope someone knows better than me.
