Overview
Buttondown is an email newsletter service that Justin Duke started as a side project to replace TinyLetter. It is now a small, customer-funded and profitable company. Writing happens in a Markdown editor with live preview, plus an optional rich-text Fancy Mode. Each newsletter gets a hosted public archive and embeddable signup forms, and can send from a custom domain. Publishers can also sell paid subscriptions through Stripe, with name-your-price options. Buttondown takes no cut of that revenue, so only Stripe fees apply. Developers get a documented REST API, signed webhooks, an official CLI, RSS-to-email, and full CSV export on every plan. Pricing is modular. The first 100 active subscribers are free. After that, a base price scales with your active subscriber count: about 9 USD per month near 1,000 subscribers and about 29 USD near 5,000, with roughly 17 percent off for annual billing. Features are added in three bundles. The 9 USD bundle adds tagging, segmentation, paid subscriptions, surveys, analytics and RSS-to-email. The 29 USD bundle adds automations, sponsorships, multiple newsletters and a custom archive domain. The 79 USD bundle adds teams and whitelabeling. Registered nonprofits get 50 percent off the subscriber price. Integrations include Zapier, Stripe and Memberful, and the vendor says it has over 40 integrations in total. Buttondown fits independent writers, open-source projects, and technical teams who value data ownership and fast, personal support. Its main limitation is that it is not a marketing automation suite. It has no native A/B testing, no drag-and-drop email builder, and no ecommerce flows. Its automations are linear, its analytics are light and opt-in, and it has no SOC 2 certification.

Pros & Cons
Pros

- A 50 percent nonprofit discount applies to subscriber pricing.

Cons

- There is no drag-and-drop email builder, and reviewers say design options are limited for non-coders.
- Analytics are light and opt-in, and users cannot add their own third-party tracking scripts.
- Key features such as tagging, automations and teams cost extra, so real costs can sit well above the 9 USD headline.
