It would be nice…

It’d be nice to have a tool to uncover the zombie email addys, but until then, read this from @wise_laura: http://bit.ly/jxjZ9M Kelly Lorenz

There’s currently not a programmatic way to make those determinations, but this is where the relationship between senders and receivers comes in. All you have to do is ask recipients what they want. I know, I know, most marketers have a low opinion of the ability or desire of their recipients to respond to an email. And there are some actual challenges to getting a recipient’s attention when they’ve tuned out a particular sender or type of email.
Separating out zombie addresses from real addresses is a challenge. But it’s part of maintaining a healthy email marketing program. When I’m working with clients who are mailing old lists we first talk about their product and their goals. Then we look at what information they have for recipients. My goal is to separate out those addresses we know are good from those we know are bad from those we don’t know. It’s the ones in the don’t know category that we focus on.
I don’t recommend just deleting the addresses that are non-responsive. One of the reasons is that I read mail with images off by default and so I often look like one of those non-responsive recipients even when I’m actively reading and receiving mail. Instead, I like to look at what other data the customer has about a recipient to help classify them. Of course, there are often a subset of users we cannot identify if they’re zombies or not. For these addresses we plan a re-engagement campaign.
Clients who have gone through this process have seen an improvement in delivery and an improvement in responses and ROI.
Until and unless ISPs start rejecting mail for zombie accounts it’s the best chance senders have to separate the barely there from the not there at all.

Setting expectations at the point of sale

In my consulting, I emphasize that senders must set recipient expectations correctly. Receiver sites spend a lot of time listening to their users and design filters to let wanted and expected mail through. Senders that treat recipients as partners in their success usually have much better email delivery than those senders that treat recipients as targets or marks.
Over the years I’ve heard just about every excuse as to why a particular client can’t set expectations well. One of the most common is that no one does it. My experience this weekend at a PetSmart indicates otherwise.
As I was checking out I showed my loyalty card to the cashier. He ran it through the machine and then started talking about the program.
Cashier: Did you give us your email address when you signed up for the program?
Me: I’m not sure, probably not. I get a lot of email already.
Cashier: Well, if you do give us an email address associated with the card every purchase will trigger coupons sent to your email address. These aren’t random, they’re based on your purchase. So if you purchase cat stuff we won’t send you coupons for horse supplies.
I have to admit, I was impressed. PetSmart has email address processes that I recommend to clients on a regular basis. No, they’re not a client so I can’t directly take credit. But whoever runs their email program knows recipients are an important part of email delivery. They’re investing time and training into making sure their floor staff communicate what the email address will be used for, what the emails will offer and how often they’ll arrive.
It’s certainly possible PetSmart has the occasional email delivery problem despite this, but I expect they’re as close to 100% inbox delivery as anyone else out there.

Zombie email: Part 2

In zombie email: part 1 I talked about how email addresses were tightly tied to internet access in the very early years of the internet. We didn’t have to worry about zombie email addresses because when an account was shut down, or ignored for a long time then mail would start bouncing and a sender could stop sending to that account.
There were two major changes to email accounts in the early 2000’s that led to the rise of zombie emails.
People started decoupling their internet access from their email addresses. Free addresses were easy to get and could be checked from everywhere. No longer did they have to dial in to get email, they could access it from outside the office and outside the home. Mobile devices, including the first generation of smart phones and laptops, helped drive people to use email addresses that they could access from any network. The easy access to free mail accounts and the permanence led people to adopt those addresses as their primary address.
When people changed addresses, for whatever reason, they didn’t have to stop paying. There was no way to tell the free ISPs to stop accepting mail for that address. Free mail providers would let addresses linger for months or years after the user had stopped logging in. Sometimes those addresses would fill up and start bouncing email, but they were not often turned off by the ISPs.
The lack of purging of abandoned addresses was the start of dead addresses accumulating on mailing lists. But there weren’t that many addresses in this state, and eventually they would fill up with mail. When they were full the ISP would stop accepting new mail for that account, and the address would bounce off a mailing list.
Everything changed with the entrance of Gmail onto the scene. When Gmail launched in 2004 they were providing a whole GB of storage for email accounts a totally unheard of storage capacity. Within a year they were providing multiple gigabytes of storage. Other freemail systems followed Gmail’s lead and now all free accounts have nearly unlimited storage. Plus, any mail in the spam folder was purged after a few weeks and bulk mail doesn’t count against the users’ storage quota. Now, an abandoned email account will almost never fill up thus senders can’t use over quota bounces to identify abandoned accounts.
Now we’re stuck in a situation where SMTP replies can’t be used to identify that there is no one home inside a particular email account. Senders can’t distinguish between a quiet subscriber and an abandoned address. ISPs, however, can and are using zombie addresses as a measure of a senders reputation.
On Monday we’ll talk about why and how zombie addresses can affect delivery. (Zombie emails: part 3)
Tuesday, we’ll talk about strategies to protect your list from being taken over by zombies. (Zombie Apocalypse)
