What it does
Buttondown is a newsletter service for writers and publishing teams. It offers an editor, personalization, automations, analytics, integrations and an application programming interface (API) for custom integrations. A free account covers the first 100 subscribers.
The core Buttondown workflow is a publication: write in rich text or Markdown, send from a custom domain and keep editions in hosted archives. That combination suits a writer publishing a technical digest who wants readable email and a web archive without building a separate publishing application. The first 100 subscribers are free.
Its modular billing is worth understanding before designing a larger workflow. Tagging and segmentation, analytics, RSS-to-email, paid subscriptions, automations and teams appear as separate add-ons. A writer sending manually needs a different combination from a publication that imports a feed and triggers sequences. The base sending assumption is no more than one email per day to the whole list; more frequent sending needs a separate usage discussion. For example, a weekly Markdown digest can use the base editor and hosted archive, while a feed-driven publication also needs the RSS-to-email add-on.
Create an account through Sign up to start a publication. Tagging, analytics and RSS-to-email each add USD $9 per month; automations add USD $29 per month. The Teams add-on costs USD $79 per month without a separate charge per collaborator.
