Sounds like you're over-thinking it to me. Since I realised I have subscribers, I decided to send a Medium newsletter - e.g. a round up of the week's stories in a single post. I untick the 'send to subscribers' option in my individual stories, so they don't get bombarded by up to three stories a day. Then they get a periodic round up or my recent stories. So they don't get bombarded, but they do get a newsletter. There's no reason to take it off Medium at all. Obviously I leave the 'send to subscribers' box ticked for that one.
