Back from MAAWG

Had an all too short trip to M3AAWG. It was great to see old friends and meet new folks. I have lots to talk about and a poll to get into the field once I get caught up on client work.

While I’m deep in the depths of my inbox, I thought I’d share a bit of insight into the question of new domain vs. subdomain that often comes up.

I can’t stress this enough. subdomain.example.com can/should/will inherit things like reputation and history and other good (or badness) from example.com, where as somethingnew-example.com starts at ground zero and looks suspect/phishy/killit with fire to anti-abuse eyes. I can’t tell you how badly my kill it with fire instinct was twitching when I saw the Equifax breach domain name. Guy who Writes the Filters at an ISP you Know.

Equifax’s domain choice was so bad their own customer support folks were sending concerned consumers to the Wrong Domain. DNS is a hierarchy. Use it!
Subdomain. Always subdomain. ALWAYS. A different ISP rep said much the same recently – subdomains inherit some reputation from the parent domain.

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.

February 2017: The Month In Email

Happy March!

As always, I blogged about best practices with subscriptions, and shared a great example of subscription transparency that I received from The Guardian. I also wrote about what happens to the small pool of people who fail to complete a confirmed opt-in (or double opt-in) subscription process. While there are many reasons that someone might not complete that process, ultimately that person has not given permission to receive email, and marketers need to respect that. I revisited an older post on permission which is still entirely relevant.
Speaking of relevance, I wrote about seed lists, which can be useful, but — like all monitoring tools — should not be treated as infallible, just as part of a larger set of information we use to assess deliverability. Spamtraps are also valuable in that larger set of tools, and I looked at some of the myths and truths about how ISPs use them. I also shared some thoughts from an industry veteran on Gmail filtering.
On the topic of industry veterans, myths and truths, I looked at the “little bit right, little bit wrong” set of opinions in the world of email. It’s interesting to see the kinds of proclamations people make and how those line up against what we see in the world.
We attended M3AAWG, which is always a wonderful opportunity for us to catch up with smart people and look at the larger email ecosystem and how important our work on messaging infrastructure and policy really is. I was glad to see the 2017 Mary Litynski Award go to Mick Moran of Interpol for his tireless work fighting abuse and the exploitation of children online. I also wrote about how people keep wanting to quote ISP representatives on policy issues, and the origin of “Barry” as ISP spokesperson (we should really add “Betty” too…)
Steve took a turn as our guest columnist for “Ask Laura” this month with a terrific post on why ESPs need so many IP addresses. As always, we’d love to get more questions on all things email — please get in touch!
