How do unengaged recipients hurt delivery?

In the comments Ulrik asks: “How can unengaged recipients hurt delivery if they aren’t complaining? What feedback mechanism is there to hurt the the delivery rate besides that?”
There are a number of things that ISPs are monitoring besides complaint rates, although they are being cautious about revealing what and how they are measuring things. I expect that ISPs are measuring things like:

  • How many users read a particular mail?
  • How many users click through on a particular mail?
  • How many users have the senders from: address in their address book?
  • How many users receiving the mail have abandoned their accounts or not logged in for months?
  • How many users never open a particular mail?

Some of these values senders can measure as well. Senders know, for instance, how many users click through on a mail. They know that some people do open the mail, and they know that some people don’t open the mail. The numbers on opens are not always completely accurate, as to measure opens the recipient must load HTML images. But images are not rendered by default in a number of email clients, and some ISPs don’t show images unless the recipient agrees, or the sender is in the recipient’s address book or the sender is certified by a 3rd party.
Senders don’t have any way of knowing, however, if an email account has been abandoned. That’s something that only the ISPs know. Because of the tools that senders have, there is no difference between an account that doesn’t load images and doesn’t click on any links and one that has been abandoned. Both of these cases will hurt a sender’s reputation, but the abandoned account will hurt more. The ISP figures that if you’re sending mail for months and months to recipients who don’t even log in, that you’re not engaging readers and sending mail recipients want.
What can senders do?

  • Senders with websites requiring a login can disable email to that user. The users account can be  and notify users that they will need to resubscribe to the email list when the user next logs in at the site.
  • Senders that do not have registration can send re-engagement campaigns to recipients who have not clicked or opened a mail. Users that do not interact with the mail are dropped from the list.

Yes, you will lose names off your list. But those are people who aren’t interested enough in your mail to read it or click on anything for months and months. What value is that name bringing to your business? Does that value outweigh the reputation hit that continuing to mail non-responsive addresses brings?

The legitimate email marketer

I cannot tell you how many times over the last 10 years I’ve been talking to someone with a problem and had them tell me “but I’m a legitimate email marketer.” Most of them have at least one serious problem, from upstreams that are ready to terminate them for spamming through widespread blocking. In fact, the practices of most companies who proclaim “we’re legitimate email marketers” are so bad that the phrase has entered the lexicon as a sign that the company is attempting to surf the gray area between commercial email and spam as close to the spam side of that territory as possible.
What do I mean by that? I mean that the address collection practices and the mailing processes used by self-proclaimed legitimate email marketers are sloppy. They don’t really care about individual recipients, they just care about the numbers. They buy addresses, they use affiliates, they dip whole limbs in the co-reg pool; all told their subscription practices are very sloppy. Because they didn’t scrape or harvest the email address, they feel justified in claiming the recipient asked for it and that they are legitimate.
They don’t really care that they’re mailing people who don’t want their mail and really never asked to receive it. What kinds of practices am I talking about?
Buying co-reg lists. “But the customer signed up, made a purchase, took an online quiz and the privacy policy says their address can be shared.” The recipient doesn’t care that they agreed to have their email address handed out to all and sundry, they don’t want that mail.
Arguing with subscribers. “But all those people who labeled my mail as spam actually subscribed!!!” Any time a mailer has to argue with a subscriber about the validity of the subscription, there is a problem with the subscription process. If the sender and the receiver disagree on whether there was really an opt-in, the senders are rarely given the benefit of the doubt.
Using affiliates to hide their involvement in spam. A number of companies use advertising agencies that outsource acquisition mailings that end up being sent by spammers. These acquisition mailings are sent by the same spammers sending enlargement spam. The advertiser gets all the benefits of spam without any of the consequences.
Knowing that their signup forms are abused but failing to stop the abuse. A few years back I was talking with a large political mailer. They were insisting they were legitimate email marketers but were finding a lot of mail blocked. I mentioned that they were a large target for people forging addresses in their signup form. I explained that mailing people who never asked for mail was probably the source of their delivery problems. They admitted they were probably mailing people who never signed up, but weren’t going to do anything about it as it was good for their bottom line to have so many subscribers.
Self described legitimate email marketers do the bare minimum possible to meet standards. They talk the talk to convince their customers they’re legitimate:

The coming changes

Yesterday I talked about how I’m hearing warnings of a coming paradigm shift in the email industry. While these changes will affect all sender, ESPs in particular are going to need to change how they interact with both ISPs and their customers.
Currently, ESPs are able to act as “routine conveyers.” The traffic going across their network is generated by their customers and the ESP only handles technical issues. Responsible ESPs do enforce standards on their customers and expect mailings to meet certain targets. They monitor complaints and unknown users, they monitor blocks and reputation. If customers get out of line, then the ESP steps in and forces their customer to improve their practices. If the customer refuses, then the ESP disconnects them.
Currently standards for email are mostly dictated by the ISPs. Many ESPs take the stance that if any mail that is not blocked by the ISPs then it is acceptable. But just because a certain customer isn’t blocked doesn’t mean they’re sending mail that is wanted by the recipients.
It seems this reactive approach to customer policing may no longer be enough. In fact, one of the large spam filter providers has recently offered their customers the ability to block mail from all ESPs with a single click. This may become a more common response if the ESPs don’t start proactively policing their networks.
Why is this happening? ISPs and filtering companies are seeing increasing percentages of spam coming out of ESP netspace. Current processes for policing customers are extremely reactive and there are many ESPs that are allowing their customers to send measurable percentages of spam. This situation is untenable for the filtering companies or the ISPs and they’re sending out warnings that the ESPs need to stop letting so much spam leave their networks.
Unsurprisingly, there are many members of the ESP community that don’t like this and think the ISPs are overreacting and being overly mean. They do not think the ISPs or filtering companies should be blocking all an ESPs customers just because some of the customers are sending unwanted mail. Paraphrased, some of the things I’ve heard include:

AOL EWL: low complaints no longer enough

This morning AOL announced some changes to their Enhanced White List. Given I’ve not talked very much about the AOL EWL in the past, this is as good a time as any to talk about it.
The AOL Enhanced Whitelist is for those senders that have very good practices. Senders on the EWL not only get their mail delivered to the inbox, but also have links and images enabled by default. Placement on the EWL is done solely on the basis of mail performance and only the best senders get on the list.
The new announcement this morning says that AOL will take more into account than just complaints. Previously, senders with the lowest complaint rates qualified for the EWL. Now, senders must also have a good reputation in addition to the low complaint rates. Good reputation is a measure of user engagement with a particular sender.
This change only reinforces what I and many other delivery experts have been saying: The secret to good delivery is to send mail recipients want. ISPs are making delivery decisions based on those measurements. Send mail that recipients want, and there are few delivery problems.
For a long time good delivery was tied closely to complaint rates, so senders focused on complaints. Spammers focused on complaints too, thus managing to actually get some of their spam delivered. ISPs noticed and started looking at other ways to distinguish wanted mail from spam. One of the better ways to separate spam from wanted mail is to look at user engagement. And the ISPs are measuring engagement and using that measurement as part of their decision making process. Send so much mail users don’t read it, and your reputation goes down followed by your delivery rates.
