Setup checklist#
- ☐ Add your sending domain and verify with a TXT record.
- ☐ Send consistently for a few days so data appears.
- ☐ Check spam rate daily; stay under 0.1% and never above 0.3%.
- ☐ Investigate any day domain reputation drops from High.
- ☐ Correlate authentication failures with new sending sources.
Audit checklist#
- ☐ Confirm you are not: verifying the root domain but sending from an unverified subdomain.
- ☐ Confirm you are not: reading reputation as a single day rather than a trend.
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
Frequently asked questions#
Why is Postmaster Tools empty?
Volume is too low for Gmail to report, the domain is not verified, or you are looking at the wrong domain (From versus DKIM d=).
