Dead Addresses

Vodafone New Zealand: sorta shutting down

Vodafone NZ is shutting down mail handling for the following domains as of today, Nov 30, 2017.

Verizon changes but no time line

Yesterday there was a lot of talk about Verizon moving out of email and transitioning all their customers over to the AOL backend. The source was a page in the Verizon help center about transitioning an email address. There is no date on the page, so it’s unclear when this is going to happen or when it started.
I posted about Verizon beginning this transition back in May of 2016: Changes coming to Verizon email. The wording on the AOL page I link to is very similar to the wording on the page that was passed around yesterday.
Without a date it’s hard to really provide any advice, other than to maintain your list hygiene (you do have list hygiene programs, right?) and remove addresses that hard bounce. Quite honestly, I don’t think this will really have any effect on delivery. It doesn’t appear these changes are happening all at once, and Verizon customers have the option to keep their verizon.net address. They’re just going to have to access it differently.
For companies that use an email address as a primary key for logins or accounts, it’s probably a good time to contact customers with a verizon.net address and ask them to update their address. That’s a good idea most of the time, but when we know changes are happening at a domain level, it’s a requirement.

Yahoo trying to cope with misdirected email

Techcrunch says Yahoo is announcing a new “this is not me” button for email sent to recovered addresses.

Yahoo retiring user IDs: why you shouldn't worry

A couple weeks ago, Yahoo announced that they were retiring abandoned user IDs. This has been causing quite a bit of concern among email marketers because they’re not sure how this is going to affect email delivery. This is a valid concern, but more recent information suggests that Yahoo! isn’t actually retiring abandoned email addresses.
You have to remember, there are Yahoo! userIDs that are unconnected to email addresses. People have been able to register all sorts of Yahoo! accounts without activating an associated email account: Flickr accounts, Yahoo groups accounts, Yahoo sports accounts, Yahoo news accounts, etc,. Last week, a Yahoo spokesperson told the press that only 7% of the inactive accounts had associated email addresses.
Turning that around, 93% of the accounts currently being deactivated and returned to the user pool have never accepted an email. Those addresses will have hard bounced every time a sender tried to send mail to that address.
What about the other 7%? The other 7% will have been inactive for at least a year. That’s a year’s worth of mail that had the opportunity to hard bounce with a 550 “user unknown.”
If you’re still concerned about recycled Yahoo userIDs then take action.

Reputation: part 2

Yesterday, I posted about reputation as a combination of measurable statistics, like bounce rates and complaint rates and spamtrap hits. But some mailers who meet those reputation numbers are still seeing some delivery problems. When they ask places, like AOL, why their mail is being put into the bulk folder or blocked they are told that the issue is their reputation. This leads to confusion on the part of those senders because, to them, their reputation is fine. Their numbers are exactly where they were a few weeks ago when their delivery was fine.
What appears to have changed is how reputation is being calculated. AOL has actually been hinting for a while that they are looking at reputation, and even published a best practices document back in April. Based on what people are saying some of that change has started to become sender visible.
We know that AOL and other ISPs look at engagement, and that they can actually measure engagement a lot more accurately than sender can. Senders rely on clicks and image loading to determine if a user opened an email. ISPs, particularly those who manage the email interface, can measure the user actively opening the email.
We also know that ISPs measure clicks. Not just “this is spam” or “this is not spam” clicks in the interface, but they know when a link in an email has been clicked as well.
I expect that both these measures are now a more formal and important part of the AOL reputation magic.
In addition to the clicks, I would speculate that AOL is now also looking at the number of dead addresses on a list. It is even possible they are doing something tricky like looking at the number of people who have a particular from address in their address book.
All ISPs know what percentage of a list is delivered to inactive accounts. After a long enough period of time of inactivity, mail to those accounts will be rejected. However for some period of time the accounts will be accepting mail. Sending a lot of mail to a lot of dead accounts is a sign of a mailer who is not paying attention to recipient engagement.
All ISPs with bulk folders have to know how many people have the from address in their address book. Otherwise, the mail would get delivered incorrectly. In this way, ISPs can monitor the “generic” recipient’s view of the email. Think of it as a similar to hitting the “this is not spam” button preemptively.
This change in reputation at the ISPs is going to force senders to change how they think of reputation, too. No longer is reputation all about complaints, it is about sending engaging and relevant email. The ISPs are now measuring engagement. They are measuring relevancy. They are measuring better than many senders are.
Senders cannot continue to accrete addresses on lists and continue sending email into the empty hole of an abandoned account while not taking a hit on their reputation. That empty hole is starting to hurt reputation much more than it helps reputation.
