Postcard is now open source

In 2022, I launched Postcard as a personal website + newsletter. I had deleted social media, and wanted a way to stay in touch with friends via email. It powers my personal website, philipithomas.com, where I've published monthly "What I'm up to" every month since. Postcard's launch was well-received and thousands of people signed up. Today, many people continue to use and maintain their Postcard sites. Revenue is modest - I make dozens of dollars per month on it. But, I'm happy to maintain it because I believe dependable tools matter. Today, I still maintain Postcard and the hosted service runs on a Mac Mini on my desk.
