Mail client optimized for self-hosted email across multiple domains

Reintroducing - an open-source, Gmail-Discord hybrid email inbox for your Resend domains. I've used Resend for every project I have made in the last 2 years. But every time someone replied to any email I sent, that reply went into a webhook payload and then basically disappeared. So I built the client half. 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
