If I were making more than 1 million through Substack I would probably move from Substack.

Sure, but can't Mailerlite or whoever do equally well at a fraction of the price? The one reason I'd stay is probably if it genuinely boosts growth through app visibility and simplifying onboarding and stuff like that.

Email deliverability is really hard and you get some network effects with their app. I am usually a roll your own type of girl but here I’m genuinely not so sure…..

Probably set up my own site (or hire someone to do it if I didn't know how) and use a cheaper service for payments and email delivery. Since their cut grows with revenue I guess it would make sense to move at some point as you grow.
