Buttondown
Newsletter platform with a markdown-first composer.
Buttondown is an email newsletter service whose composer is built around markdown: you draft issues in plain markdown with a live preview, and Buttondown converts them into clean, well-rendered emails.
It handles subscriber management, archives, paid subscriptions, and analytics, while staying deliberately minimal. Writers who already keep drafts in markdown can paste them in unchanged, which makes it a favorite for developer and indie newsletters.
