Creating a Customer Newsletter to Boost Engagement and Expertise

📧 I recently started a weekly customer newsletter for our existing customers that solely focuses on providing industry related insights and expertise, not talking about our products at all. The goal is to keep us in the mindshare of existing customers for expansion opportunities by positioning us as trusted experts in the industry. The engagement has been solid and consistent, and now I'm thinking about targeting prospective customers with the same newsletter/content with the same goal: position us as experts to work with. I have some baseline ideas on how to get prospective customers to sign up for the newsletter and am curious to see what others are doing in this area. Is anybody doing this currently that can share their approach on how to get prospective customers to sign up for the newsletter and where/how to share the sign up form? Thanks!
