Google Postmaster Tools v2: Reputation Scores Are Gone — What to Track Instead

Short answer: Google retired the old reputation dashboards. Postmaster Tools v2 (rolled out through mid-2026) replaced the High/Medium/Low/Bad domain and IP reputation charts with plain-language "deliverability verdicts", absolute spam-rate percentages, and subdomain-level reporting.

What changed for senders

• No more reputation score to watch. The verdicts are simpler but coarser — many teams lost the early-warning gradient they used to catch decay before spam-foldering.
• Spam rate is now absolute and the compliance threshold remains what matters: stay under 0.1%, never sustain 0.3%+.
• Subdomain-level reporting finally matches how outbound teams actually send (marketing on one subdomain, product mail on another, outreach on lookalikes).

Rebuilding your monitoring stack after v2

1. Keep Postmaster for what only Google can tell you: spam rate and delivery errors per (sub)domain.
2. Move the early-warning function to signals you control: authentication health (SPF validity and lookup count, DKIM keys, DMARC policy), blacklist status, and record drift — these degrade before spam rates spike, and they're observable continuously rather than in Google's delayed daily windows.
3. Watch per-subdomain: v2's subdomain view means misconfigured lookalike domains are now visible to Google — make sure they're visible to you first.

That second layer is what Aurelius does: continuous SPF/DKIM/DMARC/blacklist checks with alerts on regression — the gradient signal Postmaster v2 stopped giving you. Grade any domain free with the domain grader.
