A number of people have mentioned over the last couple weeks that they’re seeing a spike in Yahoo rejecting mail with
554 delivery error: dd Requested mail action aborted
Discussions on various mailing lists indicate these messages are related to inactive accounts. Addresses that bounce at Yahoo with these codes should be handled as inactive addresses and removed from future mailings.
Today it was revealed that Yahoo has been scanning people’s email for the federal government.
Read MoreA few years ago I wrote a series of blog posts about zombie email addresses. Zombie addresses are those that someone owned and used and interacted with, but for whatever reason stopped logging into and checking. This series started with the time before the zombies, and moved on to the zombie uprising. Then discussed how they don’t eat brains, but they do love to take a bite out of deliverability. Smart marketers, however, can defeat zombies by the judicious application of the double tap.
Since that series of blog posts a few things have changed. The biggest thing is that the webmail providers are being much more aggressive about disabling email reception at addresses where folks don’t log in. I have a few addresses on different providers I use for testing purposes. I have to remember, though, that I need to log into them before sending test messages. If I don’t, they generally bounce.
This doesn’t completely remove the challenge of zombie addresses but it does make it easier for regular senders to purge their lists of zombies just through their normal bounce handling. No double-taps needed.
We’ve returned from London, where I spoke at the Email Innovations Summit and enjoyed a bit of vacation. My wrap-up post also mentions an article I wrote for the Only Influencers site, which looks at questions I get asked frequently: “Why does spam make it to the inbox and our legitimate marketing email doesn’t? Should we just copy their tactics?”
In industry news, Yahoo caught our attention for two surprising moves: disabling forwarding and — much more disturbing — creating software for intelligence agencies to search customer email.
Some legal updates this month: The Second Court of Appeals upheld an earlier ruling that companies are in fact liable for the activities of their affiliates, including spam and fraudulent claims. This is important, as we often see spammers and cybercriminals use affiliates to distance themselves from these activities. We also saw another fine assessed for a violation of CASL, and noted with appreciation the transparency and thoughtful process that the Canadian Radio-television and Telecommunications Commission (CRTC) demonstrates in explaining their actions.
Another excellent report is the one created by the Exploratorium to explain their recent experience with being phished. It’s a good piece to share with your organization, in that it reminds us that these cybercriminals are exploiting not just our technology but our trust-based connections to our friends and colleagues. It’s important to raise awareness about social engineering as a part of information security. And speaking of email security, we were delighted to note that André Leduc received the 2016 J.D. Falk award this month at M3AAWG for his excellent work on this topic. It’s a fitting legacy to our friend, J.D., who died five years ago this month. We miss him.
Finally, we’d be remiss in observing Halloween without a post about zombies. Feel free to read it aloud in your spookiest voice.
