Your warmup tool says it is working but your inbox placement disagrees. The monthly audit process that catches the gap

I trust data more than dashboards.
Warmup tools show you activity. Emails sent, replies received, network health scores. These numbers look reassuring and tell you almost nothing about whether your inbox is actually landing in primary.
The only way to know if warmup is working is to run an inbox placement test in GlockApps. Not once when you set up the inbox. Monthly, ongoing, as a check against what the warmup dashboard claims.
The audit process I run on all my PuzzleInbox Google Workspace inboxes every 30 days.
First: run a GlockApps test from every active inbox. I send to their seed list, which includes Gmail, Outlook, Yahoo, and corporate mailboxes. The report shows exactly where each email landed: primary, spam, promotions, missing. Target: 85 percent inbox placement minimum. Anything below 80 percent needs investigation before you touch a cold list.
Second: compare the placement score to the warmup dashboard. If the dashboard says inbox health is strong and GlockApps says 62 percent inbox placement, the warmup is not working the way the tool represents it. This has happened to me twice. Both times the fix was switching warmup providers.
Third: check the warmup-to-cold ratio. For every cold email I send from an inbox, I want at least 30 to 40 percent of that inbox's daily volume to be warmup traffic. If I send 20 cold emails per day, I want 6 to 8 warmup emails running in parallel. This signals to Google that the inbox has normal, varied email activity, not just outbound blasting.
Fourth: check for blacklist listings on MXToolbox every 30 days. Warmup does not protect you if a domain gets listed. You need to catch blacklist listings fast because the longer a domain sits on a list, the harder the delisting process becomes.
The warmup tool is not the safety net. This audit process is.
GlockApps tests run about 10 dollars each. I spend 50 to 70 dollars a month testing inbox placement across all my domains. That expense has saved me from running campaigns on degraded inboxes at least four times in the last year. Test your inboxes. Do not trust the dashboard alone.
