How to Monitor Domain Health After Launching Google Workspace

Launch day is not the finish line. Domains decay when DNS drifts, vendors get added silently, or complaint rates creep up. A light monitoring routine prevents surprise spam-folder disasters.

Weekly checks (15 minutes)

• Google Postmaster Tools — spam rate and domain reputation trends.
• DMARC aggregate summary — new unauthorized sources?
• Bounce and complaint rates from your CRM/helpdesk.
• DNS diff — did anyone change MX/SPF without review?

Monthly checks

• DKIM still authenticating in Admin Console.
• Unused users suspended.
• App Passwords revoked for tools you no longer use.
• DMARC policy still appropriate (raise enforcement if reports are clean).

Red flags

• Sudden spike in DMARC fails from a single IP range.
• MX pointing back to an old host.
• Users forwarding everything to personal Gmail (security + deliverability smell).
