No failures → no email.\n\n### Setup (~4 minutes)\n1. **n8n API credential** on both n8n nodes (n8n → Settings → *n8n API* → create key; base URL = your instance URL).\n2. **SMTP credential** on **Send digest email**.\n3. **Config node:** set the from/to addresses (and the digest window, if you want something other than 24h).\n4. Save & **activate**.\n\n### Good to know\n- Scans the last 100 executions; very busy instance → raise the limit in *Get recent executions*.\n- Prefer a \"still alive\" email even on clean days? In *Build digest*, replace `return []` with a heartbeat item.\n\n---\n🩺 Want this without the plumbing — plus instant alerts the moment things break, volume-anomaly detection and Make.com support? **WentQuiet** → https://wentquiet.com?ref=n8n-template.
