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?

Don't take my subscribers away!

Tom Sather has a good summary of the problems with inactive email addresses and why data hygiene is critical to maintain high deliverability. These recommendations are some of the most difficult to convince people to implement.
Some of my clients even show me numbers that show that a recipient that hadn’t opened or read and email in 18 months, suddenly made a multi-hundred dollar purchase. Another client had clear numbers that showed even recipients that didn’t open for an entire year were responsible for 10% of revenue.
They tell me I can’t expect them to let their customers go. These are significant amounts of money and they won’t let any potential revenue go without a fight.
I understand this, I really do. The bottom line numbers do make it tough to argue that inactive subscribers should be removed. Particularly when the best we can offer is vague statements about how delivery may be affected by sending mail to unengaged users.
I don’t think many senders realize that when they talk about unengaged users they are actually talking about two distinct groups of recipients.
The first group is that group of users that actively receive email, but who aren’t opening or reading emails from particular senders. This could be because of their personal filters, or because the mail is going to the bulk folder or even simply because they don’t load images by default. This is the pool that most senders think of when they’re arguing against removing unengaged users.
The second group is that group of users that never logs in ever. They have abandoned the email address and never check it. I wrote a series of posts on Zombie Emails (Part 1, 2, 3) last September, finishing with suggestions on how to fight zombie email addresses.
Unlike senders ISPs can trivially separate the abandoned accounts from the recipients who just don’t load images. Sending to a significant percentage of zombie accounts makes you look like a spammer. Not just because spammers send mail to really old address lists, but a number of spammers pad their lists with zombie accounts in order to hide their complaint rates. The ISPs caught onto this trick pretty quickly and also discovered this was a good metric to use as part of their filtering.
I know it’s difficult to face the end of any relationship. But an email subscription isn’t forever and if you try to make it forever then you may face delivery problems with your new subscribers.

The perfect email

Email is a fluid and ever changing landscape of things to do and not do.
Over the years my clients have frequently asked me to look at their technical setup and make sure that how they send mail complies with best practices. Previously, this was a good way to improve delivery. Spamware was pretty sloppy and blocking for somewhat minor technical problems was a great way to block a lot of spam.
More recently filter maintainers have been able to look at more than simple technical issues. They can identify how a recipient interacts with the mail. They can look at broad patterns, including scanning the webpages an email links to.
In short, email filters are very sophisticated and really do measure “wanted” versus “unwanted” down to the individual subscriber levels.
I will happily do technology audits for clients. But getting the technology right isn’t sufficient to get good delivery. What you really need to consider is: am I sending email that the recipient wants? You can absolutely get away with sloppy technology and have great inbox delivery as long as you are actually sending mail your recipients want to receive.
The perfect email is no longer measured in how perfectly correct the technology is. The perfect email is now measured by how perfect it is for the recipient.

When the inbox isn't the inbox

There was a discussion today on the OI list about email filtering that brought up something I usually don’t mention in delivery discussions. Most email marketers treat the inbox as the holy grail of delivery. Everything about delivery is focused on getting to the magical inbox.
I think, though, that inbox is often just shorthand for “not landing in the bulk or spam folders.”
For some recipients, particularly those of us who get lots of mail, sometimes it’s better to land in a folder rather than the inbox. I have a folder set up, where most of my commercial mail goes. It’s labeled “commercial.” I check it once or twice a day.
This is beneficial to me and to the senders. Why? Because when I check that folder I’m ready to actually look at my commercial mail. I’m looking for those offers.
For someone like me, who does most of their work in their inbox, commercial interruptions are a problem. Commercial mail that ends up in my inbox, which can happen if I’ve been lazy about filters, interrupts me and usually doesn’t get read. But when it’s in my commercial folder? Well, then I can look at it, visit websites and make purchases.
So just remember, it’s not that you want mail in the inbox as much as you want mail somewhere that the recipient will notice it.
