What is an open?

I was having a discussion today with a few industry colleagues about engagement and open rates. It was a good discussion and inspired a couple blog posts. Engagement totally matters, Engagement affects deliverability, and ISPs should be the last of your concerns.
I think they’ve covered the engagement issue pretty well, but what I wanted to talk about was metrics, specifically opens. Open is a fairly simple word, and it’s used in email all the time. Recipients open email. Mailbox providers measure that open. Senders measure that open.
It’s critical to remember, though, that open rates as measured by free mailbox provider and open rates tracked by a sender are not really the same thing. They’re measured in very different ways, and there is not a 1:1 mapping between the two measurements.

  • Free mailbox providers actually track that the message was opened. They can see the status change from “unread” to “read.”
  • ESPs track when a recipient loads an image.

ESPs can’t track the status of a message inside the recipient’s mailbox. And free mailbox providers don’t need to track image loads.
So even though both groups claim they are tracking opens, how they’re tracking gives different data to the people measuring the information. Gmail sees me open mail all the time. Most of my clients never see me open an email in my gmail account.
Free mailbox providers and senders are using the exact same word (Open) to describe different things (rendering an image vs. actually opening the mail). I think these things are different enough to say that an open as measured by a free mailbox provider and an open measured by the sender are not the same at all.
The crux of it is that even though mailbox providers use the metric of “open” to look at engagement and even though senders use the metric of “open” to look at engagement, they’re actually looking at two totally different things.

One letter off…

I’m working on a blog post about the new Gmail tabbed inbox and the messages Gmail is inserting into the promotions tab. The messages aren’t showing up on most of my accounts, so I logged into an infrequently used account of mine. Ads are there, I got my screenshots and some data about the behaviour of the messages. So far so good.
I also discovered that at least two other women are using my address. One of them apparently ordered a bunch of wedding stuff from David’s Bridal shop using my email address. I hope Kirstie got her special order in time.
The other case is more interesting. I found dozens of emails in my inbox from what appeared to be friends including me in their email forward chain.
The Comic Sans. The FW:FW:FW:FW:FW subject lines. The horribly drawn cartoons. The inspirational messages. The prayer requests. The invites to bridge night. The followup demands that I reply to their invites for bridge night. The sad emails that I didn’t go to bridge night. There were emails from grandchildren. Questions about where I’d been and if I moved. Prayer chains. The messages go on and on.
Looking back through my inbox, this has been going on since sometime late in 2012. (Told you this was an infrequently used account). I looked and looked and I think I figured out what happened. A woman named Helen appears to to have an email address one letter off from mine (string@ vs stringsstring@) and one of her church friends tried to reply to her and dropped the ‘s’ from the email address. Once she did that, everyone else just kept hitting “reply all” and are including me in their forward chain.
It’s not commercial, it’s not spam. It’s just a bunch of people mistyping an email address and sending mail to someone they don’t know. I’m kinda glad it was a bunch of church ladies rather than Carlos Danger sending … well… Carlos Danger type messages.
People get email addresses wrong sometimes. It happens (ask me about the time I almost got my mailserver blocked because I mistyped an address while sending mail to a blocklist maintainer and hit a trap address by mistake…). The problem is that it can overwhelm an uninvolved person’s mailbox, even when it’s not commercial. Sure, if I was logging in to this account more often I’d probably have shut it down, but if they were paying attention they would have realized Helen is never replying to anything they send.
I kinda feel the same about commercial mailers that send me mail over and over and over again. I never open it, I never reply to it, I never respond to it. I wonder if there is actually anyone actually sending the mail, or if there’s just a lonely mailserver bricked up in a wall somewhere continually sending out spam.
Don’t be the bricked up server in the wall. Pay attention to what your recipients are doing.

Facts about engagement

It is reality that ISPs look at the population of recipients that a mail stream is going to.
It is reality that they evaluate the activity of that population.
It is reality that ISPs treat senders that are sending to a significant number of email addresses that have not been logged into or accessed recently negatively.
If you’re having delivery problems, looking at the recipients and their activity is part of troubleshooting the issue and identifying a path back to the inbox.
You can use web and purchase data as a measurement of engagement IF you have, at some point, directly linked the email address and the user.
If you don’t have something that demonstrates a direct link between the person and the address, then it’s a crapshoot as to whether or not that email address belongs to who you think it belongs to.
Happy Friday everyone. It’s been a week.

Images at Yahoo

For a while, Yahoo was giving preferential “images always on” treatment to Return Path Certified senders. The tricky part of this was the senders had to register a DKIM selector key with Yahoo. I had a lot of (somewhat rude) things to say about this particular design decision.
Over the last few months, a number of senders have complained about being unable to update their selector keys with Yahoo. (Insert more rude comments about how broken it is to use the selector as a part of reputation.) Around the same time, a few of us have noticed that Yahoo seems to be turning on a lot of images by default. A few of the ESP delivery folks collaborated with me on checking into this. They could confirm that images were on by default for some of their customers without certification and without selector key registration.
Earlier this week, Return Path sent out an email to users that said that Yahoo would no longer be turning images on by default for Return Path Certified IPs.
