I was looking for an open-source WYSIWYG email editor for my SaaS, https://courselit.app. I searched the interwebs long and hard, only to find crippled email editors that wouldn't work without a subscription. Since my SaaS is open source, I couldn’t use a paid email editor.

There were a few good options, like Postcard, Editor.js, etc., but none that I could easily integrate into my SaaS and customize. So, I built a new open-source project from scratch.

CourseLit's email editor is extensible—i.e., you can build your own blocks. It’s built on top of react.email for exporting the HTML template. Hence, the output HTML is well-tested and works out of the box in most email clients.

I’ve just readied a very minimal project, and there are only basic blocks available for now, but I’ll be adding many more blocks in the forthcoming days. If you have a feature request, please leave a comment or reach out to me on X at https://x.com/rajatsx.
