I’m considering closing the Mastodon accounts for my apps in an effort to simplify my digital life a bit. I’d move any announcements over to a blog with RSS, and mirror the announcements through some kind of a newsletter.

Are there any newsletter services out there that let you opt-in to certain “categories”? Imagine if a user wanted to get updates regarding one app but not the other, or they want to explicitly hear about both. Does such a service exist?
