Who
I needed inbound Resend mail to wake an OpenClaw agent on my machines. Local gateway path, readable UI, no SaaS inbox product.
For operators wiring Resend receiving boxes into a local agent gateway with a readable UI.
What
I built resendld, public michaelmonetized/resend-listening-daemon. HEAD 4fbec17. 46 commits. Version 0.0.0-rc.0.
src/daemon/listen.ts polls https://api.resend.com/emails/receiving every 5 seconds with pure fetch() (no Resend CLI). List has no body. Each new id hits /emails/receiving/{id}, strips HTML if text empty, writes markdown under ~/.openclaw/workspace/mail/, mirrors to Convex, then POSTs OpenClaw https://localhost:18789/hooks/agent (TLS self-signed allowed). 404/401 falls back to openclaw cron add --system-event.
Web: TanStack Start 1.82.1 + Convex inbox/detail/boxes/reply at https://resendld.localhost behind Caddy. install.sh (640 LOC) targets macOS launchd + Arch systemd.
Afternoon of Mar 23 is mostly PATH hell against resend-cli across machines: try API, revert to CLI, then land pure fetch at 28041eac. Tip #9 resolves openclaw cross-platform; ack path in gateway.ts still hardcodes /Users/michael/.bun/bin/openclaw.
Where
Code: github.com/michaelmonetized/resend-listening-daemon, public. No public deploy.
cd ~/Projects/resend-listening-daemon
bash install.sh # or --dry-run / --force / --uninstall
# edit ~/.config/resendld/boxes.json
resendld start # daemon + Convex + web :3000 + Caddy
# opens https://resendld.localhost
When
2026-03-23. Phase 0, Telegram/Convex, ~20 PATH/CLI commits, /hooks/agent, pure fetch 28041eac.
2026-03-24. Install/docs macOS+Arch (#3).
2026-03-25. HTML body fallback + web startup.
2026-03-26. TanStack Start pin to 1.82.1 (#8).
2026-03-27. Openclaw path (#9), HEAD 4fbec17. Queue pushed_at 2026-03-27T23:11:34Z.
Why
An agent that cannot receive email instructions is half-deaf. Poll Resend yourself, store locally, wake the gateway. Skip waiting on a webhook you do not control.
Engagement Q: Keep the 5s poll + seen-ids file, or move the tip to Resend webhooks into the same /hooks/agent path?
