Deliverability Incident Response
Things break. When they do, you need a playbook — not panic. This skill is the triage decision tree.
The five incident types
| Symptom | Most likely cause | First action | Fix time |
|---|---|---|---|
| Reply rate dropped sharply | Deliverability — emails in spam | Run spam placement test | 1-14 days |
| Bounce rate spiked >3% | Bad list OR domain reputation | Check bounce types | 1-3 days |
| Domain blacklisted | Shared IP bad actor OR your domain got flagged | Check blacklists, rotate if needed | 7-30 days |
| Inbox blocked in warmup | Warmup network flagged sending patterns | Pause, investigate, maybe replace | 1-7 days |
| Gmail marking as promotional | Content triggers (links, images, HTML) | Simplify content | 1-3 days |
