SPF, DKIM, and DMARC are not three decorative DNS records. The message must authenticate through the system that actually sent it, and DMARC requires the visible From: domain to align with either the SPF or DKIM domain. Google’s current email sender guidelines describe those requirements and recommend consistent volume, gradual increases, and monitoring server responses, spam rate, and reputation. ““DMARC is published” while the message itself fails alignment.” Use message headers from affected mail, not only a DNS lookup. The complete setup sequence is in the cold email domain setup guide.
Every legitimate sending system is inventoried and owned. “SPF or DKIM passes for each source, and DMARC alignment is confirmed from real headers.” Hard failures, temporary deferrals, spam placement, and reply loss are tracked separately.

Do not rotate domains without fixing the sending behavior. That only moves the same failure to a new identity. “Authentication is necessary, but reputation, complaints, recipient fit, provider policy, and content still matter.” Do not use open rate as the verdict. Google says it does not track opens and cannot verify third-party open-rate accuracy; privacy features also distort the metric.
Diagnose the symptom before prescribing the fix “Provider-specific placement tests, complaints, Postmaster data, message headers” Provider segmentation matters. A blended “delivery rate” can hide the fact that Gmail, Microsoft-hosted domains, and Yahoo are behaving differently. Use the same test message, comparable recipients, and a defined time window before calling any change a fix.
Pause the traffic that caused the incident, preserve normal business mail, capture provider-specific evidence, verify SPF, DKIM, and DMARC alignment, fix the source of complaints or failures, and resume only after controlled tests pass. There is no universal recovery timer. “A “burned” email domain is not one diagnosis.” Log the incident before the evidence disappearsUse the 33-column CSV to capture provider, SMTP, authentication, complaint, ownership, remediation, and go/no-go evidence.

Deliverability incident response·12 min read “Contain the send, diagnose the failure by mailbox provider, protect business-critical mail, and use evidence—not a countdown—to decide when to restart.” Short answer
Short answer “There is no universal recovery timer.” A “burned” email domain is not one diagnosis. It can mean messages are rejected, deferred, accepted into spam, or delivered while replies disappear. Those failure modes have different owners and different fixes. Treat the event like an operational incident before changing copy, buying another domain, or requesting delisting.
What does a “burned email domain” actually mean? “The symptom is observable; the cause is not.” Google’s Postmaster Tools dashboards separate spam rate, authentication, compliance, and delivery errors. Google also warns that the data is delayed and may be absent at low volume. A blank dashboard is therefore not proof that the domain is healthy.
What does a “burned email domain” actually mean? “Authentication failure, an abrupt volume change, recipient complaints, poor list quality, a compromised account, a shared sending IP, and content or URL reputation can all produce similar outcomes.” Google’s Postmaster Tools dashboards separate spam rate, authentication, compliance, and delivery errors. Google also warns that the data is delayed and may be absent at low volume. A blank dashboard is therefore not proof that the domain is healthy.
First 60 minutes: contain the incident “Pause the campaign, sequence, connector, or compromised account that changed the normal sending pattern.” Preserve evidence. Export SMTP responses, provider mix, sent volume, bounces, complaints, authentication results, and the last known normal date before dashboards roll over.

Hard failures, temporary deferrals, spam placement, and reply loss are tracked separately. “Suppression includes invalid recipients, complaints, unsubscribes, customers, and other approved exclusions.” The test is split by mailbox provider and uses a frozen cohort.
