Setup checklist#
- ☐ Check your IPs and domains against major blocklists weekly.
- ☐ Identify the cause: compromised account, list purchase, spam trap hits, or a misconfigured forwarder.
- ☐ Fix the root cause and document what changed.
- ☐ Submit a delisting request through the blocklist's process with evidence of remediation.
- ☐ Monitor for relisting for 30 days.
Audit checklist#
- ☐ Confirm you are not: requesting delisting before fixing the cause; repeat listings become harder to remove.
- ☐ Confirm you are not: ignoring minor blocklists that some corporate gateways still use.
Ongoing monitoring#
- ☐ Weekly: review provider dashboards (Postmaster Tools, SNDS) and bounce logs
- ☐ Monthly: re-run the setup verification after any vendor or DNS change
- ☐ Quarterly: full audit against this checklist
