How long does it take to change reputation at Gmail?

Today I was chatting with a potential client who is in the middle of a frustrating warmup at Gmail. They’re doing absolutely the right things, it’s just taking longer than anyone wants. That’s kinda how it is with Gmail, while their algorithm can adapt quickly to changes. Sometimes, like when you’re warming up or trying to change a bad reputation, it can take 3 – 4 weeks to see any direct progress.This is a screenshot of IP reputation on Google Postmaster Tools. The sender made some significant changes in mail sending on some of their IP addresses starting in mid to late December. You can see, that the tools noticed and the reputation of those IPs bad to good fairly rapidly. It took a few more weeks of consistent sending for those two IPs to switch to yellow. And it took around another month for the reputation to flip to high.
Because this company is doing all the right things, and they’re seeing (as they describe it) some small amounts of improvement, I told them to give it another couple weeks. If they weren’t happy with their progress I could help them. But, frankly, until we can tell if this is something other than a normal warmup there isn’t much else to do.
When I got off the phone I felt very much like a doctor telling a patient to take two aspirin and call me in the morning. But, honestly, sometimes that is the right answer. Give it time.

August 2017: The month in email

Hello! Hope all are keeping safe through Harvey, Irma, Katia and the aftermath. I know many people that have been affected and are currently out of their homes. I am proud to see so many of my fellow deliverability folks are helping our displaced colleagues with resources, places to stay and money to replace damaged property.
Here’s a mid-month late wrapup of our August blog posts. Our favorite part of August? The total eclipse, which was absolutely amazing. Let me show you some pictures.





Ok, back to email.
We’re proud of the enormous milestone we marked this month: ten years of near-daily posts to our Word to the Wise blog. Thanks for all of your attention and feedback over the past decade!
In other industry news, I pointed to some interesting findings from the Litmus report on the State of Email Deliverability, which is always a terrific resource.
I also wrote about the evolution of filters at web-based email providers, and noted that Gmail’s different approach may well be because it entered the market later than other providers.
In spam, spoofing, and other abuse-related news, I posted about how easy it is for someone to spoof a sender’s identity, even without any technical hacks. This recent incident with several members of the US presidential administration should remind us all to be more careful with making sure we pay attention to where messages come from. How else can you tell that someone might not be wholly legitimate and above-board? I talked about some of what I look at when I get a call from a prospective customer as well as some of the delightful conversations I’ve had with spammers over the years.
In the security arena, Steve noted the ongoing shift to TLS and Google’s announcement that they will label text and email form fields on pages without TLS as “NOT SECURE”. What is TLS, you ask? Steve answers all your questions in a comprehensive post about Transport Layer Security and Certificate Authority Authorization records.
Also worth reading, and not just for the picture of Paddington Bear: Steve’s extremely detailed post about local-part semantics, the chunk of information before the at sign in an email address. How do you choose your email addresses (assuming they are not assigned to you at work or school…)? An email address is an identity, both culturally and for security purposes.
In subscription best practices — or the lack thereof — Steve talked about what happens when someone doesn’t quite complete a user registration. Should you send them a reminder to finish their registration? Of course! Should you keep sending those reminders for 16 months after they’ve stopped engaging with you? THE SURPRISING ANSWER! (Ok, you know us. It wasn’t that surprising.)

Improving Gmail Delivery

Lately I’m hearing a lot of people talk about delivery problems at Gmail. I’ve written quite a bit about Gmail (Another way Gmail is different, Gmail filtering in a nutshell, Poor delivery at Gmail but no where else, Insight into Gmail filtering) over the last year and a half or so. But those articles all focus on different parts of Gmail delivery and it’s probably time for a summary type post.

Filtering by gestalt

One of those $5.00 words I learned in the lab was gestalt. We were studying fetal alcohol syndrome (FAS) and, at the time, there were no consistent measurements or numbers that would drive a diagnosis of FAS. Diagnosis was by gestalt – that is by the patient looking like someone who had FAS.
It’s a funny word to say, it’s a funny word to hear. But it’s a useful term to describe the future of spam filtering. And I think we need to get used to thinking about filtering acting on more than just the individual parts of an email.

Filtering is not just IP reputation or domain reputation. It’s about the whole message. It’s mail from this IP with this authentication containing these URLs.  Earlier this year, I wrote an article about Gmail filtering. The quote demonstrates the sum of the parts, but I didn’t really call it out at the time.
