I’m repeating the presentation I gave at M3AAWG in London for the Certified Senders Alliance.It’s all about how to send an email by hand, and how knowing the mechanics of how an email is sent can help us diagnose email delivery issues.We’re starting in about five hours from when I post this.Register at
Everyone has their own way of troubleshooting problems. I thought I would list out the steps I take when I’m trying to troubleshoot them. Clarify the problem. As a consultant, folks come to me asking me to help them solve their delivery problems. My first step is to get them to clarify what symptoms they’re seeing. Something happened to make them contact me, and that’s where we...
There’s an ongoing discussion, one I normally avoid, regarding how much impact an ESP has on deliverability. Overall, my opinion is that as long as you have a half way decent ESP they have no impact on deliverability. Then I started writing an email and realised that my thoughts are more complex than that. Here are some excerpts from the email, because in other circumstances I would have...
A few weeks ago we took a drive down I5 to attend a service at Bakersfield National Cemetery. Amid the acres and acres of almond farms there were patches of black from recent grassfires. Typical but boring California landscape. Wildfires are a hugely destructive but continual threat in California. Growing up on the east coast, I never really understood wildfires. How can acres and acres and...
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...
I had a number of very good talks with folks at the Email Innovations Summit earlier this week. I’m still digesting it all. It’s clear that getting to the inbox isn’t a solved problem. Around a decade ago I figured that the explosion of complaint feedback loops would make my job obsolete. That more data would mean anyone could manage delivery. That’s not the case for a...
One of the things that regularly happens at email conferences is a bunch of representatives from various ISPs and sometimes deliverability companies get up on stage and entertain questions from the audience about how to get email to the inbox. I’ve sat in many of these sessions – on both sides of the stage. The questions are completely predictable. Almost invariably, someone asks if...
More and more I’m moving away from consulting on technical setup issues as the solution to delivery problems. Delivery is not about the technical perfection of a message. Spammers get the technical right all the time. No, instead, delivery is about sending messages the user wants. While looking for something on the blog I found an old post from 2011 that’s still relevant today. In...
We’re officially halfway through 2016, and looking forward to a slightly less hectic month around here. I hope you’re enjoying your summer (or winter, for those of you in the Southern Hemisphere). Our first June blog post marked the fifteen year anniversary of the very first anti-spam conference, SpamCon. As I noted, many of the people at that conference are still working in the...
Mention an email is spam to some senders and watch them dance around trying to explain all the ways they aren’t spammers. At some point, calling an email spam seems to have gone from a statement of fact into some sort of moral judgement on the sender. But calling an email spam is not a moral judgement. It’s just a statement of what a particular recipient thinks of an email. There are...
