Engagement drives deliverability

Return Path released an white paper today offering the Secrets of Successful Senders. I don’t think any of my readers will be surprised that it boils down to identity, reputation, and engagement. Return Path treats these as separate things and I understand why they do. I think however, that the identity and reputation are supporting players to the overarching issue of engagement.

When I’m dealing with clients and troubleshooting deliverability problems and offering solutions, I focus on the root cause. To me the root cause is almost always a data problem. Either there’s a problem with data collection or there’s a problem with data maintenance. These problems result in mail going to people who don’t really want or care about it.
Yes, identity is important. But, realistically, anyone mailing through a decent ESP has SPF and DKIM in place, at least on some level. There may be better ways to authenticate, but the boxes are checked.
Yes, reputation is important. But here’s the thing, reputation just means that the ISP knows how users are going to react to an email. Reputation isn’t some nebulous concept made up by ISPs. It’s an actual measurement. It quantifies the history of an IP or a domain or a mail stream and says we know that this IP sends wanted mail. We know that this domain sends mail our users ignore. It’s a history. Past performance does indicate future results.
Identity says who a sender is. Reputation tells us that sender’s history of sending. Those are the two factors that enable ISPs to make delivery decisions. Mail comes in and the ISP looks at it. They use identity to determine what reputation to assign to a mail. Reputation drives delivery, whether into the inbox or the bulk folder.

Dueling data

One of the things I miss about being in science is the regular discussions (sometimes heated) about data and experimental results. To be fair, I get some of that when talking about email stuff with Steve. We each have some strong view points and aren’t afraid to share them with each other and with other people. In fact, one of the things we hear most when meeting folks for the first time is, “I love it when you two disagree with each other on that mailing list!” Both of us have engineering and science backgrounds, so we can argue in that vein.

One of the challenges of seemingly contradictory data is figuring out why it seems to disagree. Of course, in science the first step is always to look at your experimental design and data collection. Did I do the experiment right? (Do it again. Always do it again.) Did I record the data correctly? Is the design right? So what did I do differently from what you did? For instance, at one of my labs we discovered that mixing a reagent in plastic tubes created a different outcome from mixing the reagent in glass vials. So many variables that you don’t even think of being variables that affect the outcome of an experiment.
