I think it really depends on the content. I have a software product that manages all kinds of data. To raise awareness, I also have a newsletter that I send out a couple times a month. In the newsletter, I try to educate people about data issues and how computers process data. I try to make it interesting to people who might never even try out my software (https://didgets.substack.com/ https://didgets.substack.com/). While the purpose of the newsletter is to get people interested in looking at my product, I try not to push it too much. I don't enjoy newsletters that are nothing more than a sales pitch.
