DMARC is the newest of the authentication protocols. It compares the domain in the From: address to the domains authenticated by SPF and DKIM. If either SPF or DKIM pass and they are in the same organizational domain as the domain in the From: address then the email is authenticated with DMARC. I wrote A Brief DMARC primer back in 2014 – when Yahoo deployed p=reject late on a Friday and...
A common complaint about the advice or answers any deliverability person gives is that the generic answer to questions is: It Depends. This is frustrating for a lot of folks because they think they’re asking a simple question and so, clearly, there should be one, simple, clear answer. The problem is that there is almost never one answer in deliverability and details do matter. Let’s...
Deliverability matters because we are the conscience of our companies. We are the ones who tell our companies, and particularly the marketing team, no. We’re the ones looking out for the health of our company reputation, the recipient’s inbox and the email ecosystem as a whole. What is deliverability? On the surface, deliverability is the job that ensures email makes it to the inbox...
Welcome to deliverability week. I want to especially thank Al for doing a lot of work behind the scenes herding this group of cats. He’s an invaluable asset to the community. The topic today is why deliverability matters to me. Until I started writing this, I hadn’t really thought about it much. Like most folks, I kinda fell into deliverability. I still describe myself as a scientist...

I apparently gave chess.com an email address in 2007 – probably due to a client engagement? I don’t know. I unsubscribed from their mail at some point as there has only been one email from them between 2010 and 2021. Maybe this time they’ll actually unsubscribe me.
History Return Path was a major driver for the establishment of Feedback Loops (FBLs) back in the mid to late 2000s. They worked with a number of ISPs to help them set up FBLs and managed the signup and validation step for them. In return for providing this service to senders and receivers, they used this data as part of their certification process and their deliverability consulting. Return Path...
One of the most common refrains I hear from folks with delivery problems is that the filters must have changed because their mail suddenly started to go to the bulk folder. A few years ago, I posted about how even when there is no change in the sender’s behavior, reputation can slowly erode until mail suddenly goes to the Gmail bulk folder. Much of that still applies – although the...
There is an ever increasing amount of spam I am getting from various companies asking for links here on WttW. The Answer is No. We do not have paid links. We do not have sponsored posts. Any links on the site are done at our whim and because we have something to say about your company. The only place we offer links is on the ESPs and Purchased Lists post. And, I gotta tell you, if you buy my...
These last few years have been something, huh? Something had to give and, in my case, that something was blogging. There were a number of reasons I stopped writing here, many of them personal, some of them more global. I will admit, I was (and still am a little) burned out as it seemed I was saying and writing the same things I’d been saying and writing for more than a decade. Taking time...
