What Replaces the Reputation Dashboards in Google Postmaster Tools?

What Google says

Google's page on the deprecation of the old Postmaster Tools interface says (checked September 2026):

• "Thanks to helpful sender feedback, we're postponing the deprecation of the legacy Postmaster Tools web interface." The old interface stays available for now.

• "All the dashboards in old Postmaster Tools are available in v2, with the exception of the Domain and IP Reputation dashboards, which will be retired."

• The new v2 API "will encompass all existing v1 functionality, except Domain and IP reputation," and the v1 API "will be retired."

• The page gives no date for retiring the old interface ("Stay tuned for more information on timing"), the reputation dashboards or the v1 API.

Google's reasons: reputation data "is not easily actionable for most senders," changes in sender behavior "are slow to reflect," and the dashboard "can be misleading as reputation is only one of many factors affecting deliverability." Google says a new dashboard will replace it.

So the postponement covers only the legacy interface: the reputation dashboards and the v1 API are still going away, with no published date. Plan your monitoring without them.

What to use instead

The Postmaster Tools dashboards page lists what v2 shows:

The delivery error reasons Google lists include "Rate limit exceeded", "Suspected spam", "Email content is possibly spammy", "Sending IP has a low reputation", "Sending domain has a low reputation", "Domain is in one or more public RBLs", "IP is in one or more public RBLs" and "Bad or missing PTR record". When the reason says low IP or domain reputation, you have the answer the old grade used to give, tied to real rejected mail.

The Postmaster Tools API returns the same kind of data, including spam rate, delivery errors and compliance status.

Limits for cold email

• Personal Gmail only. Google says "Data in Postmaster Tools only applies to messages sent to personal Gmail accounts" (see Set up Postmaster Tools). Cold email to Google Workspace business addresses does not show up.

• Volume thresholds. Dashboards "might not include all data on days when your outgoing email volume is low." Cold email domains that each send small volumes often show nothing.

• Not real time. Data is typically updated within 24 hours.

What to watch instead

For cold email, the signals that cover Workspace recipients are your own:

1. Bounce and deferral texts from your sending logs. See 550 5.7.1 and 421 4.7.28.

2. Warmup inbox and spam rate per mailbox, split by provider.

3. Placement tests with a neutral control email.

4. Replies and auto-replies per mailbox and per domain.

What we recommend at Outreach2day

Each mailbox shows its warmup inbox, spam and bounce rate, and placement tests show which Google and Outlook seed inboxes received your email. Use those alongside Postmaster Tools, and still fix the causes it points to. For the public side of the same picture, the domain reputation check reads a domain's blocklists, SPF, DKIM, DMARC and age in one report.
