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

“Forward any thread and Sauna drafts a reply in my voice on the same thread.”
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.
SendGrid 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 SendGrid 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.

Yes. Unlike most tools, Sauna lets you link as many SendGrid accounts as you need — each with its own reconnect and remove controls.
Sauna reads only what you connect, and acts only after you approve. Your workspace and its memory are yours, not training data.
