What to do when something breaks.
Planned Step-by-step procedures for the failure modes that actually happen in production email. None published yet. The 10 below are the priorities. Each runbook will include diagnosis, mitigation, and prevention.
The first ten, by severity.
Sev-3DMARC alignment is failing on a third-party senderSev-2Inbox placement dropped below 90Sev-2Your sending IP appears on a blocklistSev-2Gmail Postmaster Tools shows a complaint spikeSev-1DKIM rotation broke in-flight messagesSev-3Webhook subscription auto-paused after 25 failuresSev-3Mailbox connection token expired without refreshSev-3DMARC RUA reports stopped arrivingSev-1Hard-bounce rate crossed the 5% thresholdSev-2Reply classifier returning low-confidence on all replies
In the meantime: until runbooks ship we handle these by hand. Email info@emaildigit.com when something goes sideways and we'll walk you through the fix. There is no published response time, because none is measured yet.
