> <i>To use custom domains, you’ll be charged a one-time $50 fee per publication.</i><p>I wonder why they're doing this. Substack is already taking 10% of revenue which is huge.<p>I think a better model would have been to offer it for free to paid newsletters so it's considered a premium feature and it can't be abused by their users not generating any revenue.
This is great news since it decreases the lockin / leverage that Substack has over individual writers on the platform. It's a creator-friendly choice and I respect that Substack is putting their money where their mouth is in that respect!
Honest question: Is it actually hard to implement (securely) custom domains? In the long term I want to offer custom domains for my product (which does not exist yet).
