About each tool
Buttondown
Minimal newsletter tool for people who just want to write in markdown and hit send
Buttondown is the newsletter tool for people who think ConvertKit has too many features. Write in markdown, send to your list, done. No drag-and-drop editors, no complex automation flows, no features you will never use.
Built and run solo by Justin Duke. The $9/month starting price is the cheapest in the newsletter space. The tradeoff is obvious: if you want referral programs, A/B testing, or complex automation, you need a different tool. If you just want to write and send a newsletter without the tooling getting in the way, Buttondown is refreshingly simple.
