Capture
Give every important send a probe address
Each probe gives you a dedicated address that collects campaign samples without changing how the real campaign is sent.
Telemetry
Track quality drift across launches
Keep the probe in CC or BCC so quality changes show up over time instead of only during a one-off preflight test.
Collaboration
Share one evidence trail across teams
Use the same run history and health scores when engineering, QA, and marketing need to triage launch issues fast.
