Email deliverability audit and rescue

Use this skill when emails hit spam, open rates drop, a domain or IP gets blocklisted, or a sender wants a deliverability audit before scaling volume. Triggers: "why are we going to spam", "audit my email setup", "open rates dropped", "we got blocklisted", "warm up this domain", "check my deliverability". Produces a severity-ranked audit or a root-cause diagnosis with a recovery plan and the thresholds to monitor.
