Field notes
Letter Kit uses Markdown rather than a drag-and-drop builder, then renders each issue for email delivery and a permanent public page with an RSS feed. Its prepaid model allocates 10,000 emails for $10, expires unused credit monthly, and refuses a send that would exceed the balance. The homepage also says required unsubscribe headers, a postal address, and working unsubscribe links are enforced during rendering rather than left to individual templates.
