Buttondown for Open source projects

Keep your open source project's users in the loop with Buttondown's simple and powerful email newsletter and subscription service.

Keep watchers and stakeholders in the loop with a simple, powerful email and subscription service. (And of course we offer RSS out of the box.)

Some things that make Buttondown particularly great for open source projects:

  • We're huge fans of Open Source, and pledge to consistently donate 10% of profits back to the open source solutions that power our software.
  • We run in the open as much as possible, always looking to open-source whatever non-core IP we can.
  • We offer non-tracking email newsletters, so you can be sure that your users' privacy is respected.
  • If your open source project is a registered non-profit, we offer a 50% discount on all plans (proof of registry must be emailed to concierge@buttondown.com).
  • We have a robust API that you can use to integrate Buttondown into your existing workflows.

Plus many more powerful features that benefit open source newsletters!

Overall, I'm a big fan of Buttondown and would highly recommend it to anyone looking for a great newsletter tool that doesn't get in the way.
