Email won't do, you want to e.g fix typos after publishing. I also think that there's something powerful in "all posts in one file" strategy. You might revise drafts more often, read older posts again to expand on them etc. I'm going to try that
So on the server, write the emails to a single file in Dropbox. Like .mbox with markdown level 1 instead of headers. Default input by email, revisions or alternate new via dropbox.
