Sending you can audit
How you know it is working.
Messaging mistakes are expensive and public. These controls exist so a flow never fires against a profile that should not have received it.
Per-profile inspection
Trace any event to the profile it resolved to, and see why.Deduplication
One order produces one event, so a single purchase cannot trigger the same flow twice.Bot and fraud filtering
Automated traffic never becomes a profile, so list quality and deliverability are not paying for it.
