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.

Gmail survey rough analysis

I closed the Google Postmaster Tools (GPT) survey earlier today. I received 160 responses, mostly from the link published here on the blog and in the M3AAWG Senders group.
I’ll be putting a full analysis together over the next couple weeks, but thought I’d give everyone a quick preview / data dump based on the analysis and graphs SurveyMonkey makes available in their analysis.
Of 160 respondents, 154 are currently using GPT. Some of the folks who said they didn’t have a GPT account also said they logged into it at least once a day, so clearly I have some data cleanup to do.
57% of respondents monitored customer domains. 79% monitored their own domains.
45% of respondents logged in at least once a day to check. Around 40% of respondents check IP and/or domain reputation daily. Around 25% of respondents use the authentication, encryption and delivery errors pages for troubleshooting.
10% said the pages were very easy to understand. 46% said they’re “somewhat easy” to understand.
The improvements suggestions are text based, but SurveyMonkey helpfully puts them together into a word cloud. It’s about what I expected. But I’ll dig into that data. 
10% of respondents said they had built tools to scrape the page. 50% said they hadn’t but would like to.
In terms of the problems they have with the 82% of people said they want to be able to create alerts, 60% said they want to add the data to dashboards or reporting tools.

97% of respondents who currently have a Google Postmater Tools account said they are interested in an API for the data. I’m sure the 4 who aren’t interested won’t care if there is one.
47% of respondents said if there was an API they’d have tools using it by the end of 2017. 73% said they’d have tools built by end of Q1 2018.
33% of respondents send more than 10 million emails per day.
75% of respondents work for private companies.
70% of respondents work for ESPs. 10% work for retailers or brands sending through their own infrastructure.
That’s my initial pass through the data. I’ll put together something a bit more coherent and some more useful analysis in the coming week and publish it. I am already seeing some interesting correlations I can do to get useful info out.
Thank you to everyone who participated! This is interesting data that I will be passing along to Google. Rough mental calculation indicates that respondents are responsible for multiple billions of emails a day.
Thanks!

What does good IP Reputation get you?

Today I was discussing some mailing list posts with an ESP colleague. He was telling me some interesting numbers he’d collected from different IP pools they maintain. He was testing routing mail through IPs based on subscription process and routing based on engagement metrics. The data showed that inboxing rates were similar across the test groups. As he put it, “IP reputation didn’t have much impact on inbox delivery.”

I’m not surprised. I’ve been talking for a while about how IP reputation is less important in reaching the inbox. In fact, it was almost 5 years ago now that I wrote The Death of IP Based Reputation. I updated it in 2015 with Deliverability and IP Reputation. Overall, IP reputation is a much smaller piece of reaching the inbox now than it has been in the past. I’ve talked about the reasons for this in the above posts. The short version is:

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.
