Is there a self-hosted alternative to Substack?

Ghost.org has membership features and email integration.

Could use the substation theme: https://substation.rdnthemes.com

You could use WordPress and some plugins (e.g. WooCommerce + Memberships + Subscriptions) to do it.

Disclosure: I work for Automattic, the parent company of WordPress.com and WooCommerce.

Not that I know beyond the stack I mentioned in my article. Ghost is another one that comes to mind.
