Free template: Website Uptime Checker with Email Alert
========================================================

What this is: an n8n workflow (uptime-checker.json) that checks a website every 10 minutes and
emails you only when it stops returning a normal response.

How to use it:
1. In n8n, go to Workflows -> Import from File -> choose uptime-checker.json.
2. Open "Check Site" and replace the URL with the site you want to monitor.
3. Open "Send Down Alert" and set your real From/To addresses and SMTP credential.
4. Adjust "Every 10 Minutes" if you want a different check interval.
5. Activate the workflow.

What we actually checked before publishing this: the workflow's structure, node configuration
and every expression were validated against n8n's own schema and expression checker (0 errors).
We did NOT run it end-to-end against a live site and a live mailbox, so treat this as a verified
starting point, not a guarantee it needs zero adjustment for your setup.
