I'm going to answer for op here and point out the product exponentially self-advertises. As more people send emails using the app, even if there isn't a "Sent with Button-down" it's easy to find out the email-sender so customer's receiving the email think to themselves, I could do that, and use that nice product!

Interestingly, this is exactly how I found about Buttondown, which I've been using for years to send my own newsletter. It also helped that it was priced way more sensibly than many alternatives, in a way that grows linearly with the number of subscribers (which is also how, theoretically, ads returns from a newsletter can grow): my then provider would meet me with a massive cliff-edge, going from $0 to about $30/month, if I recall correctly. It's a common behaviour – lock in first, then charge A LOT :)

Which makes me wonder – maybe a simple, overlooked way, to start side hustles is to replicate a service, but offer better pricing that works for niche/bootstrapped contributors, as opposed to creating niche versions of the service?
