Sauna works your Postmark: it triages what needs you, drafts replies in your voice, and runs the recurring sends — you review and approve before anything goes out.

Connect
Connect it with an API key from the library, or ask Sauna in chat and paste the key into the form it opens. Add more than one account if you need to.
Postmark is one of thousands of apps in Sauna's library. Anything not in the library, you add yourself with an API key or an MCP server — right from chat.
In context
Once Postmark is connected, Sauna reads and acts on it from plain language — across the web app, Slack, email, iMessage, and Superhuman — and waits for your approval before it writes anything.
