A question. Does sending through Substack affect this? Obviously the list health is on me, but if you're not using a custom domain but the name.substack.com, is Substack doing this new level of authentication? Is that the benefit of the Substack domain versus the custom?

Second question. If you reduce your list by 50%, are you not potentially doubling your your chance of reaching 0.03% sooner?
Unlikely, it's about removing the waste not the quality.
