Launching Enhancing Brain Newsletter: Feedback on Educational Approach

Hey all, I just moved from WordPress to Beehiiv and launched my newsletter Enhancing Brain. It focuses on brain health, brain training, improving memory, focus etc. I’ve got 1k monthly visitors to my site from search engines, and 23.5k followers on Instagram (https://www.instagram.com/enhancingbrain/), also 304.5k monthly views on Pinterest https://www.pinterest.com/enhancingbraincom/. Most popular newsletters I’ve seen curate real-time news about what's happening now, but mine is more educational, helping with memory issues, focus, brain fog etc. Would love any feedback or thoughts on this approach?
