More on Yahoo and Engagement

A friend of the blog contacted me earlier today and pointed out that the news that Dan posted about Yahoo and engagement that I blogged about last week was actually reported by George Bilbrey in a Mediapost article on August 1.

We’d contacted Yahoo about a number of sender issues since seeing inbox placement rates drop by roughly 3% this summer, and poor user response was cited as a cause of bulking. More recently, the company warned that as it improves its ability to analyze behavior to determine what users want delivered to their inboxes, some senders — even responsible mailers — may face deliverability challenges. When Engagement Began to Matter

My apologies to the fine folks at Return Path, especially Christine and Melinda who did all the hard work, for missing their initial report on this.

Engagement based delivery makes testing tricky

Yesterday I wrote about how important recipients are to achieving good delivery. The short version of yesterday’s post is that delivery is all about engagement, and how the ISPs were really focusing on engagement and proving custom user experiences.
This is great, for the user. Take the common example where a commercial list has some highly engaged recipients and a bunch of recipients that can take or leave the mail. The ISP delivers the newsletter into the inbox of the highly engaged recipients and leaves it in the bulk folder of less engaged recipients.
With user focused delivery people get the mail they are interested in where they can read it and interact it. People who have demonstrated a lack of interest for a topic or a sender don’t see that mail.
This can get complicated for those of us trying to troubleshoot deliver problems, though. I have a couple mail accounts I use for testing at various ISPs. Even though I do very little to try and personalize the account I am seeing behaviour that leads me to wonder if ISP personalizing the inbox experience is going to make it that much more difficult to troubleshoot delivery issues.
I have to wonder, too, where this leaves delivery monitoring services in the future. If delivery is personalized, how can you know that the delivery monitoring addresses are representative any longer? Is there even a “representative” mailbox any longer?

Bounces, complaints and metrics

In the email delivery space there are a lot of numbers we talk about including bounce rates, complaint rates, acceptance rates and inbox delivery rates. These are all good numbers to tell us about a particular campaign or mailing list. Usually these metrics all track together. Low bounce rates and low complaint rates correlate with high delivery rates and high inbox placement.
