More Google issues

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.

I’ve been reliably informed by other folks in the industry that they have been told that there is an announcement coming about Google Postmaster Tools.

That’s not a great amount of information, but it’s what we have. As of this morning I checked the few dozen domains my clients use and none of them have data. I have seen other people mention that they are starting to see trickles of data over the last 24 hours.

There has been rampant speculation that this is the launch of an API, but no one who knows is talking. The folks who are talking are saying they don’t think this is an API. But we can always hope.

Google Suspicious Link Warnings

A number of folks in the sender space are reporting intermittent “This link may be suspicious” warnings on their emails. I first heard about it a few weeks ago from some clients. One wasn’t sure what was going on, the other found a bunch of malware uploaded into their customer accounts.

What’s up with gmail?

Increasingly over the last few months I’ve been seeing questions from folks struggling with reputation at Gmail and inbox delivery. It seems like everything exploded in the beginning for 2019 and everything changed. I’ve been avoiding blaming it all on TensorFlow, but maybe the addition of the new ML engine really did fundamentally change how things were working at gmail.

Google Postmaster Tools

Earlier this month Google announced a new set of tools for senders at their Postmaster Tools site. To get into the site you need to login to Google, but they also have a handy support page that doesn’t require a login for folks who want to see what the page is about.
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?
