Set up Buttondown newsletter

Project Broadsheet integrates with Buttondown, a privacy-respecting newsletter service, through a single configuration field. No tracking pixels, no link surveillance.

Integrations Updated April 17, 2026 v1.0.0

Buttondown is an independent newsletter service that does not use open-tracking pixels or click-tracking by default, and offers straightforward flat-rate pricing rather than per-subscriber tiers. Project Broadsheet treats Buttondown as the default newsletter destination; enabling it requires one field in site.json.

Create an account

Sign up at https://buttondown.email. The free tier covers up to 100 subscribers, which is enough room to get started. Paid plans begin around $9/month for 1,000 subscribers.

Configure Project Broadsheet

Open src/_data/site.json and set the Buttondown username:

"buttondown": {
  "username": "your-buttondown-username"
}

On the next build, every newsletter signup form on the site will point at your Buttondown instance. No other changes are required.

Where the signup form appears

  • The site footer, in the Newsletter column.
  • The blog index page.
  • Any custom page that includes the newsletter partial: {% include "partials/newsletter.njk" %}.
