+1. Custom domains are (less than) table stakes in my book.

I took this approach in the e-commerce space a decade ago, and assumed that no serious merchant would ever dream of paying for an e-commerce solution that required them to link to a subdomain on another company's domain to take orders.

I was wrong. In fact, a lot of merchants saw the third-party domain as a status thing. There were thousands of merchants in one tribe and thousands in another. They are still doing it today, including at levels of commerce that prove that I was not just off, but that I totally misread the market.

An argument against custom domains being a "premium" feature, then? If you don't have a paid plan, then you have to bring your own domain. Paying gets you the *.example.com status symbol. Makes sense — a custom domain usually requires technical expertise and some amount of inconvenience for users (not unlike a services company that publishes their source code to GitHub, which you can always set up and maintain for yourself, but if you want to use the company's hosted services, then you have to pay). Another part of the value proposition would be, "You're gonna have to spend money one way or another — either to a registrar or to us — so why not let it be us?"

Not just a status symbol. Small merchants know that customers need to trust who they are paying. When customers see *.commercebrand.com they feel way better than when they are asked to enter their credit card on, say, a sushi restaurant's domain. Hell, so do I.

It depends on how much trust they put behind the domain name and operating company. People trust amazon which trickles down to sellers on it.

People trust few domain extensions more than others even though many of them are similarly priced and available. It's all about who else is using the same extension. .com? Used by most companies. .news ? no one? not trust worthy then.

It's somewhat fascinating to me that the bigger the company, the more trust people put in their verification of actors employed on the platform. Intuitively, I would think the more actors in a company - the less trustworthy or verified the actors would be.

Yes, it is refreshingly open compared to the walled gardens it seems like everyone else is trying to make.

I say, give it a few years :)

If they take away the custom domain option, that's quite a canary. So useful in either case.

Medium did it and it wasn't received well. I hope Substack learns from their Mistake.

They already did. This is the return of an existing feature.

Agree. $50 is totally reasonable for a custom domain and free email sending. You'd pay that in 2-3 months using hosted Ghost, Mailchimp, ConvertKit, Wordpress, etc.
