Google Postmaster bad IP reputation

There are widespread reports this morning (9/11/17) that Google postmaster tools is showing bad IP reputation for IPs starting on 9/9. This issue is affecting just about everyone. Looking through my client’s postmaster pages, I’m seeing red for IP reputation on every client. Even my clients with generally good reputation are seeing bad reputation since 9/9. 

This looks like a reporting or a display error on the part of Google. Many people who are reporting the bad IP reputation are not seeing any significant change in Gmail deliverability.
Looking through client data it appears that domain reputation reporting stopped on 9/8. I am seeing FBL reports for 9/9 and 9/10, for some but not all clients.
My current read on the situation is that something broke internally with the Gmail postmaster reporting. This does not currently appear to be affecting delivery of mail. (If anyone sees differently, drop me an email or tweet me @wise_laura).
I know folks are making sure Google knows. I know that some Gmail folks were directly notified and another Google person is active on Mailop. And we have confirmation that they are aware and are working on fixing it. I will let you know if I hear of a fix timeline.
EDIT: It’s been fixed. Google even fixed the older data. Same client, screenshot from this morning.

July 2017: The month in email

August is here, and as usual, we’re discussing spam, permissions, bots, filters, delivery challenges, and best practices.

One of the things we see over and over again, both with marketers and with companies that send us email, is that permission is rarely binary — companies want a fair amount of wiggle room, or “implied permission” to send. There are plenty of examples of how companies try to dance around clear permissions, such as this opt form from a company we used to do business with. But there are lots of questions here: can you legitimately mail to addresses you haven’t interacted with in 5 years? 10 years? What’s the best way to re-engage, if at all?
We frequently get questions about how to address deliverability challenges, and I wrote up a post about some of the steps we take as we help our clients with this. These are short-term fixes; for long-term success, the most effective strategy is sending email that people want and expect. Engagement is always at the core of a sustainable email program.
We’ve also discussed the rise of B2B spam, and the ways in which marketing technologies contribute to the problem. B2B marketers struggle to use social and email channels appropriately to reach customers and prospects, but still need to be thoughtful about how they do it. I also wrote about some of the ways that marketing automation plugins facilitate spam and how companies should step up to address the problem. Here’s an example of what happens when the automation plugins go awry.
I wrote a few posts about domain management and the implications for security and fraud. The first was about how cousin domain names can set users up for phishing and fraud, and the second was a useful checklist for looking at your company’s domain management. We also looked at abuse across online communities, which is an increasing problem and one we’re very committed to fighting.
I also highlighted a few best practices this month: guidelines for choosing a new ESP and active buttons in the subject line for Gmail.
And finally, we celebrated the 80th birthday of the original SPAM. If you’re a regular reader of this blog, you probably already know why unwanted email is called SPAM, but just in case, here’s a refresher….

Sharing access to Google Postmaster Tools

As a delivery consultant, I always ask clients to share their Google postmaster reports with me. As Gmail is one of the bigger delivery challenges for a lot of senders, having access to the postmaster tools helps tease out issues. I had some issues earlier this week getting access to tools and so brought up a conversation on one of the delivery lists. The nice folks there helped me get it solved.
A few hours later someone asked me how do I get access and I thought that was a brilliant idea for a blog post today.

Another way Gmail is different

I was answering a question on Mailop earlier today and had one of those moments of clarity. I finally managed to articulate one of the things I’ve known about Gmail, but never been able to explain. See, Gmail has never really put a lot of their filtering on the SMTP transaction and IP reputation. Other ISPs do a lot of the heavy lifting with IP filters. But not Gmail.
While I was writing the answer I realized something. Gmail was a late entrant into the email space. AOL, Hotmail, Yahoo, even the cable companies, were providing email services in the 90s. When spam started to be a problem, they started with IP based blocking. As technology got better and content filtering became viable, improvements were layered on top of IP based blocking.

Gmail didn’t enter the mailbox market until the 2000’s. When they did, they had money, lots of hardware, and internal expertise to do content filtering. They didn’t start with IP based filtering, so their base is actually content filtering. Sure, there were some times when they’d push some mail away from the MTAs, but most of their filtering was done after the SMTP transaction. The short version of this is I never really pay any attention to IP reputation when dealing with Gmail. It’s just another factor. Unless you’re blocked and if you get blocked by Gmail, wow, you really screwed up.
Gmail does, of course, do some IP based blocking. But in my experience IP filters are really only turned against really egregious spam, phishing and malicious mail. Most email marketers reading my blog won’t ever see IP filters at Gmail because their mail is not that bad.
Other companies aren’t going to throw away filters that are working, so the base of their filters are IPs. But Google never had that base to work from. Their base is content filters, with some IP rep layered on top of that.
That’s a big reason Gmail filters are different from other filters.
