# boolean_smtp_health_check_result

> Fires after the scheduled health check has probed one connection and recorded the outcome on it.

Action · Tier A · Since 1.0.0

Fires for healthy and unhealthy connections alike, so a monitoring integration can track every check; the plugin's own alert channels only react to failures.
