Mythbusting deliverability and engagement

Yesterday I published an article talking about an engagement webinar hosted by the EEC and DMA. I made a couple predictions about what would be said.

  1. ISPs do monitor engagement, even if they do it differently than senders thought.
  2. Engagement is important for inbox delivery at some ISPs.
  3. Different ISPs have different ways of making inbox decisions.
  4. Engagement will matter more in the future.

And, yes, all those things were said. The ISPs told us quite a bit about what they look for when making delivery decisions.
ISPs monitor engagement, measured by what users do with the mail. Do they delete it without opening it? Do they move it from the bulk folder to the inbox? Do they whitelist the sender?
ISPs also measure inactive accounts. Some use the mail to inactive accounts as a metric in their delivery decisions. Some don’t. AOL deletes accounts that haven’t logged in for 180 days. (Personal note: logging into AIM counts as a login and they don’t delete your account if you use AIM.)
Some ISPs use engagement as part of their overall reputation metrics. Other ISPs don’t. Outlook, for instance, doesn’t use engagement other than to make decisions about an individual email and the recipient. At Gmail, however, the individual user actions bubble up and affect the overall delivery of a mail.
This is really one of the first times it’s been so clear to me how different the specifics of filtering are at the different ISPs. I mean, I always knew that they all had their special secret sauce. Recent client experiences have also taught me that what works to get mail back into the inbox at one ISP doesn’t always work for another ISP. Hotmail/Outlook (sorry, I am old school enough I haven’t mentally branded them “outlook.com” yet) treats bounces (user unknowns) as a major factor. Other ISPs use spam trap accounts as a major factor in their decisions.
And, while it was never explicitly said, engagement is not going away as a factor in delivery decisions. Filters and algorithms may change, but senders are going to have to focus more and more on sending the emails people really want to receive in order to get to the inbox.

Campaign Monitor has an interview with Gmail looking at how to get mail to the Gmail inbox. It’s a great article and I think everyone should go read it.
One of the most important things it talks about is how complex filters are.

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.

Delivery and engagement

Tomorrow is the webinar Mythbusters: Deliverability vs. Engagement. This webinar brings together the ISP speakers from EEC15, plus Matt from Comcast, to expand on their comments. There’s been some confusion about the impact of engagement on delivery and whether or not senders should care about recipient engagement.
My opinion on the matter is well known: recipient engagement drives delivery to the inbox at some providers. I expect tomorrow we’ll hear a couple things from the ISPs.
