Mailbox reputation recovery: correct the cause before resuming

Define the decision

Reputation is not a switch the application can reset. A recovery attempt should address the cause that produced complaints, rejection or poor placement. Reconnecting credentials or replacing a display name does not establish recovery.

Work through the procedure

1. Pause the affected stream and preserve provider responses.
2. Review authentication, audience sources, complaints and missed exclusions.
3. Correct the identified cause and test the relevant path with controlled recipients.
4. Resume only a reviewed cohort with explicit stop conditions and accountable monitoring.

Worked example

The following is a synthetic example for this procedure, not a customer result or performance benchmark.

Cause found: opt-outs in a disconnected inbox were not reviewed
Correction: restore receiving access and process outstanding requests
Restart gate: suppression verified across active enrollments
Monitoring: new failures and requests handled before expansion

Read the result

The example ties recovery to a concrete failure. Where the cause remains unknown, state that uncertainty and seek provider evidence rather than claiming an arbitrary rest period will repair the mailbox.

Check before moving on

1. Preserve historical suppression through reconnects or migrations.
2. Compare the same provider and sending path after the correction.

Limits and next action

Do not promise recovery within a fixed number of days. Domain changes or new mailboxes should not be used to continue contacting recipients who already objected.
