Do you have a "Powered by Substack" somewhere in your free/paid newsletters?

Our product is also exposed to our customers' customers, so this has been a huge growth driver for us. Similar story for Statuspage, Intercom, etc.

Just as a link in the footer. Substack is also in the domain name, though. Thanks for the advice!

So every newsletter is sent through the same domain? Aren't you afraid of one newsletter affecting the reputación of another one?
