I nearly cut my free plan retention out of fear. I measured first, and the change did nothing. Backstory first, because that's the honest order. I pay for OpenAI, Anthropic and Cursor. Every one has its own dashboard, none of them agree with each other, and none agree with the invoice. What I actually wanted was boring: what did this feature cost last month, and which customers are expensive to serve.

You paste your Resend API key, inboxes imports your full history, and you get an actual inbox for every domain - threading, full-text search with from: / has:attachment operators, undo send, scheduled send, snooze, rules, shared aliases, roles. Discord-style sidebar, Cmd+1-9 to switch domains. Gmail shortcuts (because why not). Agents get to work alongside you in your inboxes too (but not too much). There's an MCP server for Claude Code, Codex, opencode etc. Your agent can read, search, and write drafts, but 'only' with your direction. Draft-first by default so it's opt-in only on actual replies/sends from the agent (has to be toggled in the app). $5/mo per o
