Blackboxes and unknown effects

In my previous career I studied the effect of alcohol on developing embryos. It’s a bit weird I ended up in that field because embryological development always seemed to complex to me. And it was and is complicated. In a lot of ways, though, it was good training for deliverability. We dealt with a lot of processes that seem, on the surface, straightforward.
Fertilization happens, then you get a flat group of cells, those cells fold up into the neural tube, cells migrate around, things happen, limbs form, organs form and 21 days later you have a fluffy little chick.
The details in all those steps, though. They’re a bit more complicated, looking something like this:
There are lots of different things going on inside the embryo to take it from a single cell up to a complex multicellular being. Genes turn on, genes turn off at different times in development, often driven by overlapping concentration gradients. Genes turn each other and themselves on and off. It’s complex, though, and there are things that happen that we don’t quite understand and have to black box. “If I add this protein, or take this gene and that gene away… what happens?”
A lot of that is like what email reputation is these days. There isn’t one factor in reputation, there are hundreds or thousands. They interact with each other, sometimes turning up reputation, sometimes turning down reputation. We figure this out by poking at the black box and seeing what happens. Unlike development, though, delivery rules are not fixed. They are changing along the way.
It’s not simple to explain delivery and how all the moving parts interact with each other. We don’t always know that doing A will lead to X. Because A -> X is not a straight line and there are other things that impact that line. Those other things also impact A, X and each other.
Delivery is a tangled web. On the surface it seems simple, but when you start peeling back the layers you discover the jumble of factors that all interact with each other. It’s what makes this a challenging field for all of us.

thirty.years.com

Thirty years ago this Sunday, symbolics.com was registered – the first .com domain. It was followed, within a few months, by bbn.com, think.com, mcc.com and dec.com.
Symbolics made lisp machines – symbolics.com is now owned by a domain speculator.
BBN is a technology R&D company who’ve worked on everything. If I had to pick one thing they were involved with it’d be the Internet Message Processor – the router used on the very first Internet nodes. They are still around, as a division of Raytheon.
Think.com made some amazing massively parallel computers. Their hardware group was bought out by Sun, who were bought out by Oracle and think.com now redirects to a broken error page at oracle.com.
Mcc.com were the first – and for a while, the largest – computing research and development consortium in the US. They did groundbreaking work on everything from silicon to AI. Their domain is now a generic parked page owned by a domain speculator.
Dec.com were Digital Equipment Corporation – creators of the PDP, VAX, Alpha and StrongARM processors, amongst many other things. They were a huge company when I worked for them designing Alpha CPUs in the mid 90s, then they were acquired by Compaq, then HP, then split up. Their domain is now a personal website.
It took nearly three years to reach 100 registered .com domains and nearly 10 years to reach 9,000.
As of this morning there are 116,621,517 domains registered in .com, from (64 zeros).com to (64 letter z).com, out of a possible total of more than two googol – so there’s still a domain there for you.
221,848 of those domains in .com mention “mail”.

It depends… no more

The two most hated words in deliverability. Many people ask general questions about deliverability and most experts, including myself, answer, “It depends.”
There are a lot of problems with this answer. The biggest problem is that it’s led to the impression that there are no real answers about deliverability. That because we can’t answer hypothetical questions we are really just making the answers up.

The reason we use “it depends” is because the minute details matter when it comes to deliverability. Wether or not something will hurt or help deliverability depends on the specific implementation. Who’s doing the sending? What is their authentication setup? What IP are they using? How were the addresses collected? What is their frequency? What MTA is used? Are they linking to outside sites? Are they linking to outside services? Where are images hosted? The relevant questions go on and on and on.
I am going to stop saying it depends when answering generic deliverability questions. Instead I will be using the phrase “details matter.” Details do matter. Details are everything. Details drive deliverability.
Details Matter
The importance of details is why many deliverability people hedge their answers. The details do matter.
I will do my best to stop answering It Depends to deliverability questions. Instead, I’ll be answering with question and pointing out the details matter.

2016 Mary Litynski Award

The Mary Litynski Award is presented by M3AAWG to people who have done extensive work outside the public eye over a significant period of time. At the Dublin conference the award was presented to Rodney Joffe. A lot of other people will talk about Rodney’s accomplishments, including his role in the founding of Genuity, his work with the DMA in the early days of spam, his efforts against SMS spam and his efforts to secure the Internet infrastructure. But I have a much more personal perspective.
Rodney was seminal in changing my life and career path. Back in 1999, Rodney asked Steve to look into some DNS creativity he was testing. A few months later, Rodney invited Steve to join a new company he was founding based on that DNS creativity. We moved out the the Bay area and Steve started working for UltraDNS in early 2000.
Moving out to the Bay Area triggered my career shift into anti-spam and anti-abuse. I started working at MAPS (now Trend Micro) in their experimental consulting service division. We were the “carrot” end of the equation, where our job was to help companies minimize the abuse coming out of their networks.
After MAPS went through a round of layoffs in 2001, Rodney started recommending me as an email consultant to some of his connections in the marketing world. This work was a success and directly led to the founding of Word to the Wise and everything that flows from that.
M3AAWG has published a video where Rodney discusses his role in the history of spam and some of the other things he’s done to fight junk advertising (both fax and SMS spam). He sued junk faxers in small claims court. He was instrumental in getting SMS spam covered under the TCPA. He wrote the first global opt-out list supported by both the DMA and the ISPs and proved that global opt-out would never work. He literally pulled the plug on spamming customers.
Rodney says he’s “Not smart, just the guy who carries the bags of money and helps the smart people get things done.” I certainly don’t believe that is true. He has done things on the global scale to make the Internet a safer place for end users. But my appreciation is much more personal. I will forever be grateful to him for starting us on this path and the help and advice he gave us so many years ago.
