Over the last ~2 years I cultivated a small list of newsletters. First I'd just find several regarding a particular niche and sign up to them - auto-sorting into a particular email folder for each topic. Then I'd filter them by seeing how many seem too generic (i.e. not at the level of depth I'm interested in, or by their format (content within the newsletter or linking out of it - though both are useful), and so on. Now I receive ~9 per day M-F with little repetition between them and I find it more than sufficient.
