Email sender reputation incident triage for GTM teams
Triage an email sender reputation incident with pause authority, preserved evidence, isolated audiences, owned remediation, and a cautious restart decision.
Email sender reputation incident triage
Email sender reputation incident triage begins by limiting further harm while the team establishes what changed. A named operator needs authority to pause affected sends without waiting for a broad campaign meeting.
Open one incident record with the first observed signal, affected sender, domains, campaigns, audiences, and times. Separate observations from guesses so the technical owner can test plausible causes.
Pause the affected stream
Stop the narrowest set of scheduled or automated messages linked to the signal. Protect transactional or support mail from an unnecessary broad shutdown unless evidence shows it is involved.
Record what was paused and by whom. Confirm that connected tools cannot restart the stream through another workflow while the review is active.
Preserve delivery evidence
Save provider events, bounce categories, complaint signals, authentication results, content version, sending volume, and audience source for the affected period. Use the provider’s original labels instead of rewriting them.
Compare the incident window with a normal period using the same definitions. Do not claim a cause because two changes happened near each other.
Inspect audience and controls
Review how recipients entered the audience, which suppressions applied, and whether inactive or unverified records were included. Check that unsubscribe and complaint handling reached every connected sender.
Trace recent changes to domains, authentication, automation, templates, and list imports. Assign each suspected fault to the owner who can verify it.
Plan a limited restart
The technical and marketing owners should agree on the condition for restart. Begin with an approved audience and message whose permission and operational purpose are clear.
Monitor provider events during the limited send and keep the wider stream paused until the evidence supports expansion. Document the decision even when the result is to remain stopped.
Close with prevention work
Close the incident after affected workflows, suppressions, and ownership are verified. Link every corrective action to a person and due date instead of ending with a general reminder to be careful.
Review repeated signals on a cadence and retire unsafe import or automation paths. Preserve the incident record so a future operator can distinguish a recurring pattern from a new failure.

Frequently asked questions
Should every email stream stop during an incident?
Pause the affected stream first and broaden the hold only when evidence shows other senders or message types are involved.
When can sending restart?
Named technical and marketing owners should approve a limited audience test and review its evidence before wider sending resumes.
