Late last night folks started mentioning they were seeing data trickled into Google Postmaster tools. This morning, some of the domains for some of my clients are showing data.
Things aren’t fully back to normal, some of my clients are still showing no data for the last week. But things are getting back to normal and it looks like we will have older data.
It’s been a bit of a problematic week for Google. In the last few days they’ve had a number of outages or problems across different services. There was a major outage of Google Calendar. All email, including some spam, was delivering to the primary tab instead of the correct tab. Additionally, Google postmaster tools hasn’t been updated in over a week.

We did register, but don’t send enough mail to get any data back from Google. However, the nice folks at SendGrid were kind enough to share their experiences with me and show me what the site looked like with real data, when I spoke at their recent customer meeting.
Who can register?
Anyone can register for Google Postmaster tools. All you need is the domain authenticated by DKIM (the d= value) or by SPF (the Return Path value).
Who can see data?
Google is only sharing data with trusted domains and only if a minimum volume is sent from those domains. They don’t describe what a trusted domain is, but I expect the criteria include a domain with some history (no brand new domains) and a reasonable track record (some or all of the mail is good).
For ESPs who want to monitor all the mail they send, every mail needs to be signed with a common d= domain. Individual customers that want their own d= can do so. These customers can register for their own access to just their mail.
ESPs that want to do this need to sign with the common key first, and then with the customer’s more selective key.
How does it work?
Google collects data from DKIM and/or SPF authenticated mail, aggregates it and presents it to a Google user that has authenticated the domain.
How do I authenticate?
Not necessarily more but more information about the current Google Postmaster Tools (GPT) outage. I’ve been reliably informed by folks inside Google that they’re aware of the outage and are working on it.
