What statistics highlight the impact of Brian D Smith’s Substack newsletter on his audience?

I don’t have platform-level stats from Substack (like exact subscriber count, open rates, or growth curves) pulled into this chat, and I don’t want to make numbers up. Substack keeps most of that data private to the creator dashboard.

A few impact indicators I can point to instead:

• The Substack is integrated with my YouTube channel, podcast, and website as a primary community hub
• I actively invite readers to comment, reply, and join coaching, groups, and consults through it, and it’s become a key way people first connect with me

If you’d like, I can walk you through what metrics Substack provides creators (opens, click-throughs, paid vs free, etc.) and how those typically reflect audience impact?
