## What Buttondown is

Buttondown is software for creating and sending email newsletters. It is built for creators and businesses that run newsletters, including those offering paid subscriptions. Pricing is based on total subscriber count rather than the number of newsletters, with no additional overhead for paid subscribers.

Users can offer monthly, annual, multiple-tier and pay-what-you-like subscriptions. Buttondown supports subscriber sequences, tagged-subscriber flows and email timing automations. It can turn a blog’s RSS feed into a mailing list, publish newsletters as RSS, and send newsletters from the user’s own email account. A REST API, command-line interface and integrations allow newsletters to be managed programmatically or alongside other apps.

Pricing: Users are charged based on their total subscriber count rather than the number of newsletters, and Buttondown does not charge additional overhead for paid subscribers.
