> sending low-open-rate This is a great theory. I'm subscribed to a bunch of Substacks, and most send fewer but longer posts which I always open and read. While others treat their Substack like a Twitter feed and send out lots of short posts a day which I hardly ever open. Alex Berenson has already sent me 3 mails today, and the day isn't over yet...but there are other lesser known people who send far more. And some of those others are crypto/forex/finance writers who by the nature of their content, spam filters may view more suspiciously.
