How to Write a News Letter

i've been trying to start a blug since like 20 16. I think i read austin cleon's show your work and i was like, right, i'm going to start a personal blug. And that year i published like three block posts just because i felt as if i was shouting into the void. But with the email news letter, as soon as i got some people on the list, i kind of felt this, in a way, this responsibility - which is probably me kind of self aggrandizing it a bit. It's fearing out how to make it sustainable.
