Another good tactic is to find newsletters that cover the type of content you are creating, reach out to them, and say that you created something that might be good for their newsletter. To do this, I recommend using Google to find popular newsletters on substack and revue. Do a search like such as...site:substack.com [your content topic]. Contact the editors. Getting good content out their is the best way to build backlinks IMO.
My pleasure. Cooperpress.com has an awesome suite of newsletters, too, and their editors are pretty responsive. However, they only cover technical content related to webops.
