How to monitor and improve sender reputation with Google Postmaster Tools

Postmaster Tools is the closest thing to a Gmail reputation console. Pairing its telemetry with Mailqor keeps both outbound campaigns and internal trust aligned.

Getting access

• Verify domain ownership by publishing the TXT record from Gmail Postmaster Tools.
• Grant marketing, product, and security stakeholders read access.

Key dashboards to watch

• Spam rate: keep it below 0.1%. Investigate spikes by reviewing segmented campaigns.
• Domain & IP reputation: watch for drops from High → Medium; they foreshadow throttling.
• Feedback loop: ensure automatic suppression when users hit "Report spam".
• TLS & encryption: confirm 100% compliance to avoid deliverability penalties.

Turning insights into action

• Align segments with Postmaster metrics. If marketing sees a spike, Mailqor can warn employees to distrust impersonations.
• Use DMARC reports plus Postmaster data to identify lookalike domains fueling complaints.
• Share weekly digests so leadership sees trendlines, not just incidents.

Mailqor tie-in

• When Postmaster shows rising spam complaints, add those campaigns to Mailqor's watchlist so internal recipients know to verify.
• Use badges to prove legitimate internal announcements are safe, reducing false spam reports.

Conclusion: reputation is a shared responsibility

Marketing, security, and IT must collaborate. Postmaster Tools show external trust, while Mailqor ensures employees trust inbound email. Together they keep Gmail deliverability strong.

FAQ

What if I only send transactional mail?
