If you’re a long time user of Google’s sender reputation dashboard known as Google Postmaster Tools (what is that?), you may have already seen the warning: As of October 31, the legacy version of Google Postmaster Tools (V1) is being retired, a banner warned us across the top of our GPT dashboard.
Well, that October 31 date was October 31, 2025 – at this point, many months ago. For a time, Google had put that retirement on pause, as a kind consideration for email senders and deliverability consultants who found the reputation metrics found (only) in GPT V1 to be useful.
That pause has been lifted; GPT V1 is now being phased out. If you can still access GPT V1, expect that access to go away soon. Many folks are reporting that they only have access to GPT V2 now. I think it is reasonable to assume that Google is retiring V1 access in a way that requires them to run through a list of domains and users over time. Meaning, a script is probably running, right now, working its way down through the list of domains that have access to GPT V1, and shutting down that access. Thus, some folks may still have access to GPT V1 today, but many do not, and long term, it is expected that everyone is going to lose access to GPT V1.
Google Postmaster Tools GPT V2 is the future, and that future is now.
Surely to sadden deliverability consultants everywhere, GPT V2 does not contain the reputation indicators that V1 had. GPT V1 had IP reputation and domain reputation metrics: showing that your sender reputation was bad, low, medium, or high. While I don’t fault Google for having legitimate reasons to want to sunset this data, it found it insanely handy as feedback on reputation repair efforts. To show, over time, that reputation was being improved; that whatever remediation process we were guiding the client through was moving things in the right direction.
GPT V2 does contain excellent compliance status information, and a new deliverability analysis section, where Google provides actionable insight based on how Gmail users perceive messages from your email domain, if there's enough data available to provide guidance. Good senders will hope to see "Users signal they want to get your email messages" in this section, in GPT V2.
