Engagelab Email runs on your own machine — the client starts it, so there is no endpoint to ping. 14 installs a week from npm. Last commit 21 Sep 2026.
Send, receive, monitor and reply to email from AI agents with threaded inbox context.
Today is the operative word: we check Engagelab Email every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
